1What Is the W536 OHIP Code?
The W536 billing code in OHIP pertains to repeat consultations specifically within the realm of ophthalmology. This code is billed when a patient, initially assessed by another physician, presents the same problem and requires a second opinion or reassessment by the original consulting ophthalmologist.
Typical scenarios in ophthalmology include managing chronic conditions such as cataracts, glaucoma, or diabetic eye disease. Particularly in settings like long-term care, where patients may experience changes in vision or behavior, the W536 code allows physicians to provide follow-up care without unnecessary hospital visits.
This code is often overlooked due to the necessity of meeting specific referral requirements, including acquiring a new written request. Ensuring these administrative demands are met is crucial to avoid adjustments to lesser assessment fees.

3Eligibility Requirements
To be eligible for billing under the W536 code:
- A repeat consultation must be for the same presenting problem as the initial consultation following intervention by a different physician.
- There must be a new written request from the referring physician, nurse practitioner, or dental surgeon, which should be kept in the consulting physician's medical record. This is necessary unless the consultation occurs within a setting where common medical records are maintained, such as hospitals or multi-specialty clinics.
- Repeat consultations are not restricted by general consultation frequency limits but must meet all consultation criteria. If these requirements are unmet, the claim defaults to the fee for a general or specific assessment.
4What Your Clinical Note Must Show
This document must be retained in the patient's record within the consulting physician's medical records, except in certain shared records settings.
- Signed by the referring physician, nurse practitioner, or dental surgeon
- Attached to the patient's record
- Must demonstrate a new clinical query justifying the repeat consultation
5Weak vs. Strong Note Examples
The strong note succeeds by providing a clear clinical picture, mentioning the referring physician, and specifying the new clinical concern needing attention, whereas the weak note lacks detailed context and justification.
