Otherwise, the admission assessment isn't payable.

Explanation

Updated October 26, 2026

OHIP didn't pay this admission assessment or re-assessment because a pre-operative or pre-dental assessment was done within the previous 30 days.

What it means

Code C7 means an admission assessment (C003A) or general re-assessment (C004A) was refused because it came within 30 days after a pre-dental or pre-operative assessment. The Ministry's message says no physician may claim it in that period.

The Schedule rule is worded for the same physician: A933, C933, C003 and C004 are not eligible for payment as the admission assessment for an elective surgery patient when that physician gave a pre-operative assessment within 30 days of admission (GP41).

Common causes
