R309 – Bone - Metatarsal head
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This surgical procedure involves the excision of a metatarsal head from the foot. The service is eligible for payment to the surgeon (suffix A), surgical assistant (suffix B), and anaesthetist (suffix C). The assistant's service has 6 base units, and the anaesthetist's service has 6 base units, both with additional time units calculated based on the duration of the procedure. For each additional metatarsal head excised during the same operation, billing code E587 should be added.
When to Use
- Use R309 for the primary excision of a single metatarsal head, typically for conditions like severe hallux valgus or intractable metatarsalgia.
- Use R309 as the base code when performing multiple metatarsal head excisions, with subsequent excisions billed using E587.
Common Pitfalls
- Billing R309 multiple times for multiple metatarsal heads instead of using the primary R309 plus the E587 add-on code.
- Failing to document the specific metatarsal heads excised, which is necessary to justify the use of E587 for subsequent procedures.
Billing Tips
- Ensure the primary procedure is billed as R309 and all additional metatarsal head excisions performed in the same session are billed as E587 to avoid claim rejection.
