C447 – Subsequent visit - sixth to thirteenth week inclusive
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A subsequent visit is a routine assessment in hospital following the hospital admission assessment. C447 is specifically for subsequent visits rendered from the sixth to the thirteenth week of hospitalization, inclusive. This service includes all the - common and specific elements of an assessment, such as reviewing the patient's chart, a direct physical encounter, providing advice, and making arrangements for ongoing care. The service is limited to a maximum of three visits per patient per week.
When to Use
- Use C447 for routine hospital follow-up visits occurring between the 6th and 13th week of a patient's continuous hospitalization.
- Use this code when the patient has exceeded the timeframes for earlier subsequent visit codes like C442, but has not yet reached the 14th week threshold for C449.
Common Pitfalls
- Billing more than three visits per week for a single patient, which will trigger automatic claim rejections.
- Failing to account for the actual hospital admission date when calculating the week count, leading to incorrect code selection between C442, C447, and C449.
- Attempting to bill C447 alongside C121 for an intercurrent illness; C121 is intended for acute, separate issues and cannot be combined with standard subsequent visit codes.
Billing Tips
- Always append the E083 premium if you are the Most Responsible Physician (MRP) and meet the remuneration criteria to increase the base fee by 30%.
- If the patient is in an ICU or CCU, remember to add the C101 flat-rate premium to the C447 claim to maximize the visit value.

When a hospital in-patient is referred from one physician to another physician, the date the second physician assessed the patient for the first time is considered the 'admission date' for the purposes of determining the appropriate subsequent visit fee code.
When a hospital in-patient is transferred from one physician to another physician, subsequent visits by the second physician are calculated based on the actual admission date of the patient.
