1What Is the A435 OHIP Code?
The A435 billing code under OHIP is charged for limited consultations in the field of internal medicine. It is intended for situations that require a focused, quick assessment, such as interpreting a singular abnormal test result, evaluating whether a particular medication can be continued, or providing an abbreviated preoperative opinion for a patient in otherwise good health.
This code, billed at CAD 123.10, offers a practical solution for managing narrow referrals that do not necessitate an exhaustive evaluation. However, it is essential to distinguish when a comprehensive assessment is indeed required, as consultations that extend beyond a limited scope should fall under a different billing code such as A135.
This code is often overlooked when the referral seems initially narrow but ultimately requires a complete assessment, in which case the more detailed A135 consultation code is appropriate. Using the correct code ensures accurate billing and aligns with OHIP guidelines, optimizing both patient care and clinic administration.

| A136 | Repeat consultation | Subject to the same frequency limits as A435 | Used for ongoing follow-ups presenting similar diagnostic needs. |

3Eligibility Requirements
Eligibility for billing the A435 code requires adherence to specific guidelines:
- The limited consultation must be billed only once per two consecutive 12-month periods for the same patient, physician, and diagnosis.
- Alternatively, it can be billed once every 12 months for cases involving a different, clearly defined diagnosis.
- Importantly, any major pre-operative visit previously billed precludes a subsequent A120 assessment on the same day.
Moreover, A435 consultations can be delivered virtually via video, billed as A435A. Telephone consultations, however, do not qualify under this code.
4What Your Clinical Note Must Show
Ensure comprehensive records of the consultation include the following:
- Date and time of consultation
- Patient’s presenting issue or question
- Relevant clinical observations
- Decisions or recommendations made
- Why a limited consultation was appropriate
5Weak vs. Strong Note Examples
The strong note succeeds by providing specific clinical observations and citing clear clinical decisions, demonstrating why a limited assessment was sufficient, whereas the weak note lacks detail and reasoning.
Patient seen for a quick consultation. Advised on medication usage.
Consultation carried out to interpret recent lab results showing elevated liver enzymes.
Assessed patient's current medication and confirmed continuance is safe.
- Patient presented with elevated ALT levels.
- Reviewed current medication list.
- Recommended continued medication with follow-up monitoring plan.
