C177 – Subsequent visit - sixth to thirteenth week inclusive
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A subsequent visit is any routine assessment in hospital following the hospital admission assessment. C177 is a subsequent visit for a patient under the care of a Vascular Surgery (17) specialist, rendered during the sixth to thirteenth week of hospitalization, inclusive. This service is limited to a maximum of 3 visits per patient per week. See General Preamble page for general rules regarding subsequent visits.
When to Use
- Use C177 for routine vascular surgery follow-ups occurring between day 36 and day 91 of the patient's continuous hospital admission.
- Use C177 when managing stable vascular patients who have exceeded the timeframe for C172 (first 5 weeks) but have not yet reached the long-term care threshold of C178 (after 13 weeks).
Common Pitfalls
- Billing C177 for more than 3 visits in a rolling 7-day period will result in automatic rejection of the excess claims.
- Failing to track the patient's original admission date across physician transfers often leads to incorrect code selection between C172, C177, and C178.
- Attempting to bill C177 for an acute intercurrent illness; use C121 instead to bypass the weekly visit limit.
Billing Tips
- If you are the Most Responsible Physician (MRP), always append the E083 premium to C177 to capture the 30% fee increase, provided you meet the hospital remuneration criteria.
- Ensure your billing software calculates the visit week based on the patient's initial hospital admission date, not the date you assumed care.
