One of our physicians has billed a hospital consult (99255) with prolonged service codes (99356 and 99357). He also billed, several days later, a follow-up visit (99233) with prolonged E/M codes (99358 and 99359). Upon request, we sent documentation of the time and the services were denied. Medicare says they are bundled codes. We then sent the pages from the CPT showing that they are add-on codes, to be used in addition to the primary codes. Medicare is still insisting they are bundled and denying payment. Is anyone else dealing with this and have you had successful resolution?
