Description
Comprehensive geriatric consult limit reached - paid as geriatric consultation

Explanation

Updated October 26, 2026

OHIP paid this comprehensive geriatric consultation at the regular geriatric consultation fee: the limit of one per 2 years was reached.

What it means

Code C8 means a comprehensive geriatric consultation (A775) or extended comprehensive geriatric consultation (A770) was paid at the lower geriatric consultation fee because the maximum has been reached.

Each is payable only if the same consultant hasn't given that service to the same patient in the previous 2 years. Both need start and stop times in the chart (A118).

Common causes

  • You already billed A775 or A770 for this patient in the previous 2 years

How to fix it

  1. Check when you last billed A775 or A770 for this patient.
  2. If it was more than 2 years ago, or by a different consultant, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details such as your chart notes.
  3. Otherwise, the lower payment is correct.

Don't resubmit if

  • You billed the same service for this patient within the past 2 years.
