1What Is the A525 OHIP Code?
In the field of clinical immunology and allergy, the A525 billing code represents a Limited Consultation. This service involves a brief evaluation to address a specific, well-defined clinical question. A typical scenario includes confirming or removing a drug allergy label, determining the necessity for a specific food challenge, or interpreting isolated skin test results.
This code is appropriate when the consultation requires limited interaction and focuses on a singular diagnostic question, distinct from a comprehensive review or full allergic history-taking. It's essential that the consultation is limited in scope to qualify for billing under A525; more extensive evaluations should utilize the standard consultation code, like A625.
Commonly, this billing opportunity is missed when physicians inadvertently conduct a broader review than necessary, missing the A525 criteria. Ensuring the query is narrow and specific aids in correct billing.

3Eligibility Requirements
A525 is eligible for billing in Ontario under specific conditions. It may be conducted through virtual means, though it is eligible only as a video consultation, not by phone. Furthermore, its usage is limited to once per two consecutive 12-month periods for the same patient, physician, and diagnosis. If a clearly defined and unrelated diagnosis exists, it can be billed once every 12 months.
For hospital in-patient services, use the equivalent code C525. It's vital to adhere strictly to these conditions to ensure compliance and correct billing reimbursement. Always consult the latest OHIP Schedule of Benefits for any updates or changes.
4What Your Clinical Note Must Show
Ensure the following documents are thoroughly prepared and maintained for each A525 billing:
- Patient's medical record showing the specific question addressed.
- Documented evidence of the consultation's outcome related to the inquiry.
- Details of any virtual consultations (video-only) conducted.
5Weak vs. Strong Note Examples
The strong note succeeds because it precisely identifies the referral question, outlines evaluation steps, and clarifies the consultation's outcome. The weak note lacks detail and fails to document a specific issue.
Patient seen for allergy check. Provided general advice and reassurance.
Consult conducted to assess penicillin allergy.
Reviewed patient's historical reaction details.
Confirmed low likelihood of true allergy upon evaluation, advised on subsequent steps including safe re-exposure protocol.
- Specific symptoms discussed: rash, timing of reaction.
- Decision: allergen challenge not indicated; referral for skin testing where required.
