Wiki PA billing 20610 Denied by Medicare

[laurenortho]

Hello! Our PA has ALWAYS been paid for the injections she's done in office prior to 01/01/2015. CPT 20610 with ultrasound guidance can now be billed as 20611. However, BOTH codes are being denied as not medically necessary. I called Medicare and they said it has to do with how we're "coding" the type of service. I am making sure we're adhering to the LCD guidelines so what am I doing wrong??? Can the PA truly NEVER do an injection and get paid ever again!?!?!
