There is some confusion in our office on whether to bill 77002 when performing bilateral injections in the knee 20610, we understand that MUE edits state to bill only once but Medicare is the one payor that has been paying for both.
3. CPT codes 76942, 77002, 77003, 77012, and 77021 describe radiologic guidance for needle placement by different modalities. CMS payment policy allows one unit of service for any of these codes at a single patient encounter regardless of the number of needle placements performed. The unit of service for these codes is the patient encounter, not number of lesions, number of aspirations, number of biopsies, number of injections, or number of localizations.
Above is from NCCI Policy manual.
