R610 – Trans. Metacarpal 2nd to 5th Ray
OHIP Radiology Code — Hand and Wrist · Schedule of Benefits
This service code represents the transmetacarpal amputation of the second through fifth rays of the hand. It is a surgical procedure listed in the Hand and Wrist section of Musculoskeletal System Surgical Procedures on page of the Schedule of Benefits.
When to Use
- Use R610 for a formal transmetacarpal amputation involving the 2nd through 5th rays of the hand, typically following severe crush injury or gangrene.
- Select this code when the surgical procedure involves the removal of multiple metacarpals (2-5) as a single operative event, rather than billing individual ray amputations separately.
Common Pitfalls
- Do not bill an assistant using suffix B; if an assistant is required, you must use M400B and secure prior authorization from a medical consultant.
- Avoid billing R610 in conjunction with other ray amputation codes (such as R606 or R608) for the same hand, as this constitutes unbundling and will lead to claim rejection.
Billing Tips
- Ensure the anaesthesia unit count (7 units) is correctly referenced if you are seeking assistant payment via M400B, as this is the basis for the assistant's fee calculation.
- If the procedure is performed on a patient under 16 years of age, remember to apply the appropriate age-based premium (10% to 30%) to the base fee of $279.35.
