Genicular Nerve Injection

Question:

What is the correct code (s) to report when the physician injects the superomedial and superolateral branches of the genicular nerve for knee pain with a steroid?

Answer:

The correct code to report for this service is 64454 (Injection (s), anesthetic agent (s) and/or steroid; genicular nerve branches including imaging guidance, when performed) with modifier 52 (Reduced Services). If all 3 nerve branches of the genicular nerve (superolateral, superomedial, and inferomedial) are not injected the service is reported with modifier 52. CPT code 64454 should not be used to report a piriformis injection. Piriformis muscle injection(s) should be reported using CPT code 20552, Injection(s); single or multiple trigger point(s), 1 or 2 muscle(s).
