1What Is the A845 OHIP Code?
The A845 billing code pertains to a limited consultation within the field of medical oncology, focusing on concise assessments for targeted clinical questions. This may involve addressing whether minor findings necessitate oncology follow-up or assessing if a survivor's new symptom is related to past cancer treatment.
This code provides an efficient consultation pathway for patients with narrowly focused issues. It is particularly beneficial in settings where a complete oncological assessment is not warranted, allowing specialists to give informed opinions swiftly.
A common pitfall with A845 is using it inappropriately for cases needing a comprehensive assessment, where A445 would be more appropriate. Ensuring the right code match helps in aligning patient needs with service depth, preventing billing errors.

3Eligibility Requirements
A845 services are eligible for billing under OHIP when they meet specific criteria:
- Frequency Limits: One service per two consecutive 12-month periods for the same patient, physician, and diagnosis; and eligible once every 12 months for unrelated diagnoses.
- Virtual Care: Eligible for video consultations only, billed as A845A, in line with Appendix J for virtual care exclusivity. Telephone consultations are not permissible under this code.
- Inpatient Services: When rendered to a hospital in-patient, the equivalent service is coded as C845.
4What Your Clinical Note Must Show
Detailed documentation is essential to justify the use of A845.
- Clearly state the focused clinical question addressed.
- Include details of the assessment, aligning it with a narrow scope.
- Ensure documentation differentiates when a full consultation (A445) is needed.
5Weak vs. Strong Note Examples
The strong note succeeds by thoroughly documenting the clinical rationale and outcome, clearly demonstrating the limited scope of the consultation, whereas the weak note lacks detail and specificity.
Patient assessed for follow-up. No full assessment required. Limited consultation provided.
Patient referred for potential oncology follow-up regarding persistent fatigue post-treatment.
Focused assessment ruled out recurrence of lymphoma as the cause.
- Assessment indicated symptoms likely treatment side-effects, not recurrence.
- No further oncology follow-up needed; primary care monitoring recommended.
