Ask Dr. Z

I need some guidance on coding this case. My understanding was it is part of 20550/20551. I am being directed to use 27299 for the needling part.

"Under ultrasound guidance, a 20 gauge spinal needle was advanced into the left gluteus minimus tendon. Needling/tenotomy of the tendon was performed with simultaneous administration of 1% lidocaine solution. Subsequently a solution containing 1 mL (40mg/mL) Depo-Medrol and 4 mL 1% preservative-free lidocaine was injected into the greater trochanteric bursa. The needle was removed and hemostasis achieved."
