1What Is the A635 OHIP Code?
The A635 billing code is used to capture consultations conducted by nuclear medicine specialists, typically in scenarios requiring detailed examination beyond imaging results, such as before or after a radionuclide study or therapy. Such consultations involve the nuclear medicine physician taking a detailed history and performing physical examination. These assessments are crucial for patient management when cases present complexity or require a specialized nuclear medicine opinion.
Consultations under A635 typically occur in an office or outpatient setting and help guide treatment plans or further patient management based on findings from both the consultation and any imaging data available. Physicians should be aware that missing the comprehensive assessment element or documentation requirements can lead to issues in claim approval.

3Eligibility Requirements
For a consultation to be eligible under the A635 code, certain specific criteria must be met:
- A consultation must be initiated following a written request from a referring physician, nurse practitioner, or dental surgeon, based on complexity, seriousness, or the request for another opinion.
- A copy of the written request must be retained in the consulting physician's records, unless using shared records in hospital settings.
- The written request must identify all parties involved, including the consultant and referring provider's names and billing numbers, and specify the services needed.
Furthermore, repeat consultations for the same diagnosis are limited to one service per two consecutive 12-month periods, with exceptions only for hospital or Emergency Department settings as detailed in the scheduling frequency guidelines.
4What Your Clinical Note Must Show
To ensure compliance and eligibility, practitioners must adhere to the following documentation stipulations:
- Retain a written consultation request, signed by the referring provider, except in shared medical record settings.
- Ensure the request identifies the consulting and referring providers, along with patient identification details.
- Specify relevant information and required services in the request.
- Record start and end times of the consultation on the patient’s medical record.
5Weak vs. Strong Note Examples
The strong note is successful because it includes specific details about the patient, the referring physician, and offers a thorough written report with recommendations, aligning with documentation requirements.
