Updated: 2026-08-31
For an episodic illness (a cold, gastroenteritis and the like) at a public clinic, the general public has two routes: that clinic's own telephone booking system, or the HA Go app's "Book Family Medicine Clinic" function. Patients with hearing impairment have a third — the SMS booking service for family medicine clinics — ⚠️ but it requires registering in person at the clinic beforehand with your original identity document, undergoing a hearing assessment, and being issued a personal number before it can be used. The Hospital Authority states plainly that the chance of getting a slot through either route is "no different", and that you "need not book at any particular time" — there is no official slot-release time, and the :00/:30 tips circulating online are not an official arrangement. The systems cover the next 24 hours only, and do not let you choose a time: they assign the earliest available. From 15 August 2026, the telephone system accepts only calls with caller ID displayed; with your number withheld you will hear a recording telling you to call from another phone. Charges: for eligible persons $150 per attendance and $5 per drug item (each prescribed drug charged in four-week units). Chronic disease follow-ups do not involve chasing slots — the clinic schedules your next appointment after each visit. This article covers booking and the official rules. It does not judge whether you should use public or private care, and offers no medical advice.
What is a "Family Medicine Clinic"? How does it differ from a GOPC?
The same clinic, renamed. The Hospital Authority's general outpatient clinics and community health centres were renamed Family Medicine Clinics and Family Medicine Centres respectively from 11 October 2025, with the service as a whole called the Family Medicine Outpatient Service (government press release, 10 October 2025). The same release states: "renaming the general outpatient clinics and community health centres does not affect existing services" — follow-up patients keep their date and clinic; episodic illness patients continue to use HA Go or the telephone system.
The release also gives the reason and the then scale: the renaming implements the Primary Healthcare Blueprint's recommendation to reposition the Hospital Authority's primary care services and focus on caring for disadvantaged groups; it states that "information on the Hospital Authority's 74 Family Medicine Clinics and Family Medicine Centres is in the annex". ⚠️ That 74 is the figure on 10 October 2025, and counts clinics and centres together — a different ruler from the 76 below, so the two must not be read as a before-and-after comparison.
The clinics' own service page is explicit that the patients they care for "fall mainly into two categories — the source uses "mainly", so the classification is not exhaustive": stable chronic disease patients (diabetes, hypertension and so on), and patients with relatively mild episodic illness (colds, gastroenteritis). The booking methods for the two are entirely different — everything below about chasing slots applies only to category 2.
Who most needs to know this: anyone holding an old follow-up slip who sees a new sign on the clinic and worries they have come to the wrong place — you have not; go on the original date to the original clinic.
How many booking routes are there?
Two for day-to-day use, plus an SMS service restricted to patients with hearing impairment.
Item 1 of the Hospital Authority's FAQ on Family Medicine Clinic appointment booking, dated 4 August 2026, states: "at present the public may book through two routes provided by the Hospital Authority: the Family Medicine Clinic telephone booking system, and the "Book Family Medicine Clinic" function in the Authority's one-stop app, HA Go."
⚠️ But "two" is not all of them. The Hospital Authority's own family medicine outpatient service page lists another item: the Family Medicine Clinic SMS Booking Service (Only for Patients with Hearing Impairment), with a list of clinics offering it. So the accurate statement is: two routes for the general public; patients with hearing impairment have one more.
⚠️ But that route is not usable straight away — you must register in person at the clinic first. The Hospital Authority's service information sets out four steps:
- Apply to register — "patients with hearing impairment should attend the clinic in person during office hours — Monday to Friday 9am to 1pm and 2pm to 5pm; Saturday 9am to 1pm — bringing the original identity document, and apply at the registration counter."
- Assessment — "clinic staff will arrange a hearing assessment to determine eligibility"; an original hearing impairment card may be shown to assist.
- Register and receive a personal number — after completing the form, staff provide a personal number, the list of clinic SMS system numbers, and a booking procedure leaflet.
- Only then can SMS booking be used. The document states: "patients with hearing impairment must register at the clinic in advance in order to book by SMS thereafter."
⚠️ Two more points: to use a clinic outside the number list, "the patient must register in person at that clinic"; if the personal number is lost, "a replacement must be obtained in person at the registered clinic with the original identity card". In other words: sending an SMS at the moment you fall ill will not work — you must have registered beforehand.
| Route | Who can use it | Prior registration required? |
|---|---|---|
| Clinic telephone booking system | people registered with, or who have used, Hospital Authority services | no extra registration; but caller ID must be displayed |
| HA Go "Book Family Medicine Clinic" | as above | download HA Go, register and activate an account |
| SMS booking | patients with hearing impairment only | Yes, and in person: attend the clinic with the original identity document, undergo a hearing assessment, and be issued a personal number; only then can SMS booking be used |
| Never used Hospital Authority services | anyone | bring the original identity document and register in person at any Family Medicine Clinic |
There is no single hotline. The Hospital Authority's list of Family Medicine Clinics with telephone booking (page carries no date of its own, retrieved 2026-08-30) gives each clinic its own booking number: the list carries 76 clinics, with no duplicate clinic name. The SMS booking list on the same day also carries 76. To telephone, first find your clinic's number on that list.
Who most needs to know this: anyone who thinks one number books the whole territory — there is no such number; you call clinic by clinic.
When are slots released? The Hospital Authority states you "need not book at any particular time"
This one sentence is the thing to remember: there is no official slot-release time.
Item 3 of the FAQ, in the original: "both the telephone booking system and the HA Go function operate 24 hours a day and continuously update the consultation slots for future sessions, including appointments cancelled by patients, which the system immediately makes available to others. Besides being convenient, this avoids the system being overloaded at particular times. You may therefore book at any time and need not book at any particular time."
In one line: slots flow back in continuously and in real time; they are not tipped out in one batch at a particular hour. The Hospital Authority's wording is "continuously update… including appointments cancelled by patients" — ⚠️ "including" means cancellations are one source among others, not that every newly available slot comes from a cancellation. So "chasing slots" today really means trying repeatedly, not waiting for a particular moment.
As for "is the phone or the app easier?" — item 10 answers directly: "the chance of obtaining a slot is no different between the two routes."
The advice circulating online should be set aside. Tips such as "slots at :00 or :30" and "refresh hard at :29 and :59" circulate widely, but none of the Hospital Authority pages opened for this article on 30 August 2026 — the FAQ, the service page, the news announcement, the clinic lists, the adverse weather arrangements, the slot-quota overview — prints any slot-release time. These are popular tips, not an official arrangement.
Who most needs to know this: anyone who has set an alarm for :00 — turn it off, and try whenever you can instead.
Why won't the system let me choose a time?
Because it is designed to assign the earliest slot, not to let you pick.
Item 5 of the FAQ: "to make best use of resources and avoid wasting slots, both systems assign you the earliest available session and allocate times in order. If you do not accept the time offered you may give it up and search other sessions with remaining slots in the next 24 hours — morning, afternoon or evening — and the system will then allocate the earliest available time within the session you choose."
In other words: you can choose a broad session — morning, afternoon or evening — but not a specific time; within your chosen session the system still assigns the earliest.
Why only the next 24 hours? Item 4 explains that the two routes "are mainly for patients with episodic illness such as colds and gastroenteritis", and that extending beyond 24 hours "would not properly meet patients' need for early consultation, and would increase the chance of missed appointments and wasted slots".
If your chosen clinic is full, item 20 states that the system "links nearby Family Medicine Clinics into a network sharing consultation slots" and finds remaining slots at nearby clinics automatically. ⚠️ Note "nearby" — that means a few adjacent clinics, not all 76 across the territory.
From 15 August 2026: no caller ID, no connection
From 15 August 2026, the Family Medicine Clinic telephone booking system accepts only calls with caller ID displayed.
The Hospital Authority's announcement of 31 July 2026: 「由八月十五日起，家庭醫學診所（診所）電話預約系統只會接受使用有來電顯示號碼的預約。」 The same announcement explains why: callers currently enter their identity card or birth registration number and year of birth, and recording the source of the call means "patient details can be verified where necessary, and it prevents unlawful use of number-withheld calls to impersonate patients".
How many will it affect? The announcement quotes a spokesperson: "we estimate about 15,000 patients will need to switch to a phone with caller ID." — ⚠️ that is the Hospital Authority's own "estimate" and "about", not a counted figure.
What happens if you call anyway? "the system plays a recording asking you to call again from a phone with caller ID." (FAQ item 29)
How do you unhide the number? Taking the FAQ of 4 August 2026 as authoritative:
| Type of phone | What to do |
|---|---|
| Mobile | dial "1357" before the call for single-call display; or turn on "show my caller ID" in settings |
| Fixed line (with permanent number withholding) | dial "1357" before the call for single-call display; or ask the telephone company to cancel permanent withholding |
⚠️ Two official documents differ slightly, and both are set out here: the announcement of 31 July 2026 mentions only turning on "show my caller ID" in settings for mobiles and does not mention 1357; in the announcement, 1357 is given for fixed lines; the FAQ of 4 August 2026 gives 1357 for both. This article follows the later document, the FAQ.
HA Go users are unaffected — the rule applies only to the telephone system. Chronic disease follow-up patients are also unaffected: the announcement states "their booking process is unchanged".
Who most needs to know this: anyone used to a fixed line, or who keeps their number permanently withheld — after 15 August, calling does not "fail"; you hear a recording telling you to change phone, which is easily mistaken for a broken system.
Elderly priority slots: why did my father get one by phone when my app said none?
Because clinics reserve slots for people aged 65 or above, and you are not in that group.
FAQ item 19: "to safeguard timely access to care for elderly people, each Family Medicine Clinic reserves elderly priority booking slots for those aged 65 or above with episodic illness, having regard to the distribution and pattern of service use in its district… so a particular clinic may have general slots exhausted while elderly priority slots remain available."
Three things to note: (a) the conditions are 65 or above and having an episodic illness, both required; (b) the priority slots are available by phone and by app, not by phone only; (c) ⚠️ the Hospital Authority publishes no number or percentage for these slots — the original says only that clinics reserve them having regard to district service use. This article does not estimate.
The Family Medicine Priority Group Pilot Scheme: which four groups, and how "priority" is it?
From 4 November 2025, four disadvantaged groups can book with priority — but "priority" refers only to the moment of booking, not the order of consultation on the day.
The Primary Healthcare Commission's press release of 24 October 2025: "the Family Medicine Priority Group Pilot Scheme is launched in the Hospital Authority's family medicine outpatient service from 4 November", listing the priority groups:
| Priority group | Attached condition |
|---|---|
| Comprehensive Social Security Assistance recipients | — |
| Old Age Living Allowance recipients aged 75 or above | both the age and the allowance are required |
| Holders of a Level 0 voucher under the Residential Care Service Voucher Scheme | Level 0 only |
| Working Family Allowance recipients | eligibility runs for 12 months from the date of the approval notice |
How do you register? Two steps, both required (FAQ item 37): through the eHealth app or in person at a District Health Centre or District Health Express, registering both as a District Health Centre member and as a family medicine priority group member. When booking, select your group in eHealth first, and the system connects to HA Go's "Book Family Medicine Clinic" without re-entering your personal details.
⚠️ "Priority" does not mean queue-jumping on the day. FAQ item 43 asks directly whether booking under priority group eligibility means priority consultation or other priority service on the day. The answer: "No… your consultation time will follow the time allocated and confirmed by the system. Attend at your appointment time; the clinic serves patients in booking order."
The charge is the same. Item 42: "priority group consultations are charged under the Hospital Authority's existing fee arrangements."
Unlimited use — "at present". Item 44: "at present, priority booking eligibility carries no limit on number of uses or period." The words "at present" are in the original.
What share are priority slots? Not published. The press release of 24 October 2025 says only that the Commission will "closely monitor and evaluate the scheme's effectiveness and the use of priority slots, reserving them appropriately and adjusting the proportion as needed" — it prints no proportion or number, and this article does not estimate.
Who most needs to know this: families with a relative over 75 receiving the Old Age Living Allowance — they may already be eligible, but must register first; it is not automatic. ⚠️ Registration is not limited to the app: the Hospital Authority's wording is "people in a priority group may register through the eHealth app or in person at a District Health Centre or District Health Express, and on registering both as a centre member and a priority group member may join the scheme". A relative who cannot use the app can register in person at a centre. (After registration, priority booking itself still runs through the eHealth app into HA Go.)
Chronic disease follow-ups do not involve chasing slots
If you are a chronic disease patient attending follow-up, none of the above applies to you.
FAQ item 18: "for chronic disease patients needing follow-up, the clinic arranges the next appointment after each visit according to clinical need; no separate call or app booking is required. If you need to change the date, contact the clinic, which will make suitable arrangements according to your clinical need, for example your medication needs."
The service page says the same: follow-up patients "need not telephone to book". To change the date, call that clinic directly — you are not competing for the 24-hour slots.
How much?
For eligible persons: $150 per attendance and $5 per drug item.
The Hospital Authority's "Fees and Charges" page (charges effective 1 January 2026), the "Family Medicine Clinics (including integrated clinics)" row: for eligible persons "$150 per attendance, $5 per drug item"; for non-eligible persons "$500 per attendance, $40 per drug item". Note 7 on the same page states: "each prescribed drug is charged in units of four weeks."
A worked sum (every figure from the fee page above): an eligible person attends a Family Medicine Clinic once and is prescribed 3 drugs, each dispensed for 4 weeks: consultation $150 + drugs 3 × $5 = $165. If the same visit prescribes 3 drugs each for 8 weeks (2 charging units each): $150 + 3 × 2 × $5 = $180.
Who counts as an "eligible person"? The fee page lists three categories: holders of a Hong Kong identity card issued under the Registration of Persons Ordinance (Cap. 177), except those issued on the strength of an expired or invalid permission to enter or remain; children under 11 who are Hong Kong residents; and other persons approved by the Chief Executive of the Hospital Authority. Everyone else is a "non-eligible person".
The rules on missed appointments, cancellation and changes
Cancel at least one hour before the appointment; three missed appointments in two months suspends your access.
FAQ item 7: "cancel as early as possible and at least one hour before the appointment, by calling that clinic's telephone booking system and following the instructions." You can also cancel for yourself in HA Go. The same item states the consequence: "three missed appointments at Family Medicine Clinics — not limited to the same clinic — within the past two months results in temporary suspension from booking by phone or app; you must then attend a clinic in person to enquire."
⚠️ Note 「不限於同一間診所」 — the three are counted across the territory, not clinic by clinic.
The two routes are interoperable: a phone booking can be checked or cancelled in the app and vice versa (items 15 and 34).
A first visit still requires registration. Item 30: even after booking successfully by phone, "you must complete registration at your first attendance to verify your identity"; after that no further registration is needed, as "registration is a one-off". Clinics generally open at 8:30am (service page).
What happens to my booking in a No. 8 typhoon or black rainstorm?
Clinics suspend service while the signal is in force; the Hospital Authority writes that booking systems resume "generally about" an hour after the signal is cancelled, and you must rebook yourself.
Hospital Authority, "Special arrangements for Family Medicine Clinics during tropical cyclone warnings / 'extreme conditions' and rainstorm warnings" (page carries no date of its own, retrieved 2026-08-30): while a No. 8 or higher signal or "extreme conditions" is in force, clinics suspend service and generally resume within two hours of cancellation or in the next consultation session; patients who booked by phone or app and could not attend "may rebook once the systems resume, generally about an hour after the signal is cancelled". For a black rainstorm warning: if issued during a consultation session, service is suspended but patients who have already arrived are seen; if issued before a session, the clinic does not open. Chronic disease patients with existing appointments should follow the instructions on their follow-up slip.
Does the Hospital Authority publish how many slots each clinic has?
There is such a publication, but it is by district and by four-week average, and this article could not open the files.
The Hospital Authority has an overview page of average consultation slots at Family Medicine Clinics over the past four weeks, the page printing its own statistical period: "across the 18 districts, from 26/07/2026 to 22/08/2026", with a file linked for each of the 18 districts. ⚠️ Those district files could not be opened on 30 August 2026 — six different URLs and a second Hospital Authority server were tried — so this article cites no slot figure for any clinic or district. The page also carries clinic change notices, for example that "Siu Sai Wan Family Medicine Clinic came into service from 1 August 2026".
Ask about these
Before going to the clinic or telephoning, worth checking:
- What is my clinic's booking number? (There is no central hotline; check the list of Family Medicine Clinics with telephone booking.)
- Does my phone display its number? After 15 August you cannot book without it; dial 1357 before calling, or change the setting.
- Am I an episodic illness case or a follow-up? Follow-ups are scheduled by the clinic; no need to telephone for a slot.
- Am I (or my elderly relative) eligible for an elderly priority slot or a priority group? Elderly priority slots are for those 65 or above with an episodic illness; the four priority groups must first register as a District Health Centre member and a priority group member — through the eHealth app, or in person at a District Health Centre or District Health Express.
- If I cannot attend, did I cancel at least an hour before? Three missed appointments in two months suspends access, counted across the territory.
Frequently asked questions
- When are Family Medicine Clinic slots released? The Hospital Authority sets no release time. Item 3 of the FAQ (4 August 2026) states that the systems "operate 24 hours a day" and "continuously update the consultation slots for future sessions", and that you "need not book at any particular time".
- Is the phone or HA Go easier for getting a slot? Item 10 of the same document: "the chance of obtaining a slot is no different between the two routes."
- Can I book for the day after tomorrow? No. Both routes offer only the next 24 hours, by design, for patients with episodic illness (item 4).
- Can I specify a time? Not a specific time. The system assigns the earliest; you may give it up and search a morning, afternoon or evening session instead, but within that session it again assigns the earliest (item 5).
- What do I do about telephone booking from 15 August 2026? Use a phone with caller ID displayed. If your number is withheld, dial "1357" before the call for single-call display, or turn on "show my caller ID" in your mobile settings; fixed line users may also ask the telephone company to cancel permanent withholding (items 27 and 28).
- What does a Family Medicine Clinic charge? For eligible persons, $150 per attendance and $5 per drug item, each prescribed drug charged in units of four weeks (Hospital Authority "Fees and Charges" page, charges effective 1 January 2026). For non-eligible persons, $500 per attendance and $40 per drug item.
- How many missed appointments suspend access? Three missed appointments at Family Medicine Clinics (not limited to the same clinic) within the past two months lead to temporary suspension from phone and app booking, after which you must attend a clinic in person to enquire (items 7 and 22).
- Does a priority group get seen first on the day? No. FAQ item 43 answers "No" explicitly; on the day, service follows booking order. Priority applies only to the allocation of booking slots.
Also in this series:
- Public charges in full, the $400 A&E fee and the annual cap: “Does the $10,000 annual cap have to be applied for? A full breakdown of 2026 public hospital charges, the $400 A&E fee and fee waivers”
- How to apply for a fee waiver: “How do you apply for a medical fee waiver? A full breakdown of the $15,450 threshold for a one-person household, five categories of document and four separately running time limits 2026”
- How long a specialist referral takes: “How long is the wait for a public specialist clinic? A full breakdown of 56 figures across 8 specialties and 7 clusters, and the column with no target 2026”
- Other routes when the wait is too long: “Public waits are too long — what else is there? Nine public-private partnership programmes, the limits of the voucher, and the triage rules”
What this article does not claim
This article deliberately leaves the following out, for the reasons given:
- How many slots each clinic or district has. The Hospital Authority publishes a district overview of average consultation slots over the past four weeks, but those district files could not be opened on 30 August 2026 across six different URLs. Only the statistical period printed on the overview page is cited; no slot figure is used.
- What share elderly priority slots and priority group slots represent. Neither official document prints a number or proportion: clinics reserve them "having regard to the distribution and pattern of service use in the district", and the Primary Healthcare Commission says it will "adjust the proportion as needed". This article does not estimate.
- The step-by-step SMS booking instructions (message format, codes and so on). Only the registration conditions, assessment arrangements, personal number arrangements and cautions in the Hospital Authority's service information are cited; the message format itself is on pages 3 to 6 of that document.
- "The best time to catch a slot". None of the Hospital Authority pages opened for this article prints a slot-release time, nor any success rate by time of day. The :00/:30 and :29/:59 tips in circulation are noted only as having no official basis; they are neither relayed nor attributed to any outlet or forum.
- How many Family Medicine Clinics there are in total. The press release of 10 October 2025 says "74 Family Medicine Clinics and Family Medicine Centres"; the telephone booking list on 30 August 2026 carries 76. The two differ in both date and definition (the latter being clinics with telephone booking), so this article does not present them as one series, and claims neither as the current total.
- Whether to use public or private care, or whether your condition needs a doctor. This article covers booking procedures and official charges only. It offers no medical advice and does not compare service quality.
Provenance: compiled from official booking rules, press releases and fee schedules; every figure is marked with its source and the date the document itself prints.
