Recall Exam Dental Codes in Canada: Which Code, How Often, and What to Tell the Patient

The dental recall exam code used across Canada is 01202, listed in the national code set as Examination and Diagnosis, Limited, Oral, Previous Patient (recall). It covers an examination of hard and soft tissues, including a check of occlusion and appliances. How often a plan reimburses that code and how often a patient clinically needs the visit are two different questions, settled by two different authorities.

Front desks get caught between those two answers every day. The hygienist books the patient back at an interval the dentist set, the plan pays on an interval somebody else set, and the patient hears a number from each. The codes themselves are not complicated. Knowing which one matches the appointment that actually happened, and what the plan will do with it, is the part that takes practice.

Which Dental Recall Exam Code to Use

Canadian claims are coded with the Uniform System of Coding and List of Services, the terminological standard published annually by the Canadian Dental Association. The College of Dental Surgeons of Saskatchewan describes its two main uses as the production of fee guides and the exchange of information with insurance companies, and notes that the standard only removes ambiguity if the codes are used consistently by all users at all times.

Examinations sit in the 01000 diagnostic range, and they divide into complete examinations and limited examinations. The descriptors below are quoted from the 2024 edition of the standard as published by the Nova Scotia Dental Association. The association publishes a new edition each year, so check the current one before relying on any descriptor in a dispute.

The distinction that matters most is between 01202 and the complete examination codes. A recall examination looks at hard and soft tissues and checks occlusion and appliances. It does not include the specific tests and analysis that the complete oral examination descriptor calls for, which is why it carries a different code and a different fee. A clinic that is still settling its vocabulary for all of this will find the groundwork in what dental recall actually means.

Why the Wrong Examination Code Gets Billed

Most miscoding is not an attempt to inflate a claim. It is a default left in the software, or a habit carried over from a previous office. The regulator is nonetheless clear about the test to apply. The Saskatchewan college states that the most important criterion for identifying which code to use is factual accuracy, and that any misalignment between the service provided and the fully specified descriptor of a code means the code cannot be used. Where more than one descriptor accurately matches, the best match must be used.

That college names the complete examination codes specifically, observing that with codes 01101 to 01103 the full criteria set out for those codes is often not fulfilled. In other words, the common error runs in the direction of the higher code: a routine returning visit billed as a complete examination because the complete examination is what the chart template defaults to. The same guidance records that submitting a claim reporting incorrect procedure codes is inappropriate billing and unethical practice under the college code of ethics.

Three habits prevent most of it:

1. Code the appointment that happened, not the appointment that was booked. A recall slot where the dentist ended up doing a full workup is a complete examination. A complete examination slot where the dentist did a routine check is 01202.
2. Keep emergency and specific examinations out of the recall slot. Both descriptors say in terms that they are not to be used as a substitute for the limited examination codes.
3. Do not code from the fee, and do not code from the plan. The claim describes what was done. What the plan pays for it is decided afterwards, by the plan.

One further habit is worth naming, because it causes trouble long after the claim is paid. The code is not the chart note. The Saskatchewan guidance states plainly that the descriptors of service provided in the standard are not detailed enough to meet the record keeping requirements of provincial dental regulators, and that using those codes for record keeping purposes is not recommended. A chart entry reading 01202 records what was billed, not what was found, and it will not support the clinician if the visit is ever examined. The clinical findings belong in the note, in full, and the code belongs on the claim.

The point also cuts the other way during an audit. Where the note describes a routine check of hard and soft tissues and the claim carries a complete examination code, the mismatch is visible in the record the clinic created itself. Coding accurately and charting properly are the same piece of work approached from two ends, and the office that does one well usually finds the other easier to defend.

Clinics that find the same code queried repeatedly should read the pattern rather than re-submit, and the common causes are catalogued in this guide to why government plan claims get denied.

How Often a Recall Exam Is Covered

There is no single Canadian answer, because frequency is a plan rule rather than a coding rule. The code set says what a service is. Each plan decides separately how often it will pay for it. Two federal plans illustrate how far apart those rules sit.

The Canadian Dental Care Plan dental benefits guide, effective 1 April 2026, lists the recall examination at one in any 12 months and states that clients are eligible for up to three examinations in any 12 month period. Two details in that guide catch clinics out. Frequency limitations run on rolling periods rather than calendar years, so the clock starts at the last service rather than in January. And an emergency or specific examination billed alongside recall services counts as a recall examination, which means an unscheduled visit can consume the routine entitlement.

The federal Public Service Dental Care Plan sets different numbers for the same clinical service: a recall oral examination once every nine months, or once every six months for eligible children, and a complete oral examination once every three years. A patient who moves between those two plans keeps the same mouth and inherits a different schedule.

Neither figure can be assumed for a private plan, and the public coverage pages do not publish the detail. The plan’s own coverage page confirms that services beyond established frequency limits require preauthorisation and sends readers to the benefit grids for the limits themselves. The practical consequence for a front desk is that the interval has to be checked per patient, not remembered per plan. Offices working through the government programme for the first time will find the rest of the workflow in this guide to managing recall for government plan patients.

What Else Goes on the Recall Claim

Because the bundled packages were retired, a recall appointment is assembled from separate codes. A typical returning hygiene visit draws on several ranges at once:

• The examination: 01202.
• Scaling: 11111 for one unit of time, 11112 for two, and so on up to 11116 for six, with 11117 for a half unit.
• Polishing: 11101 for one unit, 11102 for two, 11107 for a half unit.
• Fluoride: 12113 for varnish, among the topical whole mouth options in the 12100 range.
• Radiographs: bitewings at 02141 for a single image through 02144 for four.

Two rules govern how those combine. Units of time in the standard are periods of 15 minutes or less, with a half unit being 7.5 minutes or less, so scaling units are a record of time spent rather than a judgement call. And the requirement is to use the smallest number of combined codes that still describes the service accurately, because codes represent services, and procedures normally included within a service should not be coded separately.

There is also a ceiling on the claim itself. A CDAnet notice dated 15 October 2026 reminds offices to submit up to seven procedure codes per transaction, and warns that splitting the extras into separate transactions can trigger additional carrier review and slower coverage decisions. A long recall visit with radiographs, several scaling units, polishing and fluoride can reach that ceiling.

What to Tell the Patient

The conversation goes wrong when the clinic lets the plan set the clinical interval out loud. Patients reasonably hear “your plan covers one a year” as “you need one a year”, and a patient who needs to be seen more often than that quietly stops coming.

The national position is explicit on who decides. The Canadian Dental Association position on frequency of dental care, approved in June 2005 and revised in July 2012, states that continuing care frequencies, in its words recall examinations, should be determined based on a risk assessment with respect to total oral health, including caries risk, periodontal health, cancer screening, growth and development, soft and hard tissue evaluation and the medical status of the individual patient. It adds that appropriate frequency of continuing care can only be determined by the dentist in partnership with the patient, and that barriers to access, including limits on care frequency, should be eliminated.

That gives the desk a clean separation to speak from. The interval is clinical and it belongs to the dentist and the patient. The frequency limit is financial and it belongs to the plan. Said in that order, the two numbers stop competing:

• Lead with the recommendation. “Dr Okafor has you on a six month interval because of the gum pocketing we have been watching.”
• Then place the plan beside it. “Your plan reimburses an examination once every 12 months, so one of the two visits this year will be partly out of pocket. Here is what that comes to.”
• Never quote an interval as coverage you have not checked. Rolling periods mean the date of the last service decides it, and the last service may have been at another office.
• Flag the emergency visit at the time. Where an unscheduled examination may count against the routine entitlement, the patient should hear it then, not at the next recall.

Clinics that want the wording ready in advance can adapt the openings in these recall call scripts for overdue patients, and the booking side of the same conversation is covered in the guide to filling the hygiene schedule.

Frequently Asked Questions

What is the dental recall exam code in Canada?

It is 01202. The Uniform System of Coding and List of Services describes it as Examination and Diagnosis, Limited, Oral, Previous Patient (recall), covering examination of hard and soft tissues including checking of occlusion and appliances, but not the specific tests and analysis required for a complete oral examination. It is the code for the routine returning visit rather than a first workup.

What is the difference between code 01201 and 01202?

Both are limited oral examinations with the same clinical scope. The difference is the patient, not the procedure: 01201 is the limited examination for a new patient and 01202 is the limited examination for a previous patient, which is the recall. Choosing between them is a question of whether the person has been seen at that practice before.

How often is a recall exam covered under the Canadian Dental Care Plan?

The plan’s dental benefits guide, effective 1 April 2026, lists the recall examination at one in any 12 months, within an overall limit of up to three examinations in any 12 month period. Frequency limitations run on rolling periods rather than calendar years, and an emergency or specific examination billed with recall services counts as a recall examination.

Can a complete oral examination be billed at every recall visit?

No. The complete examination codes carry their own criteria, covering history, charting, treatment planning and case presentation, and the College of Dental Surgeons of Saskatchewan notes that those criteria are often not fulfilled when codes 01101 to 01103 are used. Where the service does not match the full descriptor, the code cannot be used, and submitting an incorrect procedure code is treated as inappropriate billing.

Does a recall exam have to be six months apart?

No. The Canadian Dental Association position on frequency of dental care says continuing care frequencies should be set by a risk assessment of total oral health, and that the appropriate frequency can only be determined by the dentist in partnership with the patient. Six months is a convention, not a standard. A plan’s reimbursement interval is a separate rule that does not establish clinical need.

How many procedure codes can be sent on one CDAnet claim?

Offices are reminded to submit up to seven procedure codes per CDAnet transaction. Sending the remainder as a separate transaction can lead to additional carrier review and a slower coverage decision, so a long recall appointment is worth reviewing before submission rather than after a query comes back.

Key Takeaways

• 01202 is the dental recall exam code: Examination and Diagnosis, Limited, Oral, Previous Patient (recall). 01201 is the same examination for a new patient.
• Code the appointment that happened. The regulator’s test is factual accuracy, and any misalignment with the full descriptor means the code cannot be used.
• Frequency is a plan rule, not a coding rule. The Canadian Dental Care Plan allows one recall examination in any 12 months on a rolling period, the federal public service plan allows one every nine months, and private plans vary again.
• The bundled recall package codes were deactivated in 2003, so a recall visit is claimed as separate lines, with up to seven procedure codes per CDAnet transaction.
• Tell the patient the clinical interval first and the coverage limit second. The Canadian Dental Association puts the interval in the hands of the dentist and the patient.
