Surgical excision of the patella, to include fascial repair. This procedure is listed under the Musculoskeletal System Surgical Procedures section for the knee. The service is eligible for billing by the surgeon (suffix A), surgical assistant (suffix B), and anaesthetist (suffix C). The basic units for a surgical assistant are 6, and for an anaesthetist are 7.

When to Use

Use R312 for the formal surgical excision of the patella when the procedure includes the necessary fascial repair.
Select R312 when performing a total patellectomy, as the code explicitly incorporates the required fascial reconstruction into the procedural fee.

Common Pitfalls

Do not bill R312 in conjunction with other knee arthrotomy or patellar stabilization codes unless a distinct, unrelated procedure is performed at a different site, as R312 is considered a comprehensive procedure.
Avoid billing a hospital admission assessment or subsequent hospital visits on the same day as the surgery, as these are considered included in the surgical fee unless the visit qualifies as the major pre-operative assessment.

Billing Tips

Ensure the operative report clearly details the extent of the fascial repair to support the use of R312, as this is a specific component of the code definition.
If performing bilateral patellectomies, bill the major procedure at 100% and the second procedure at 85% of the fee, ensuring the surgical assistant and anaesthetic units are calculated based on the major procedure only.
