With chemo 96413 I have 4 separate infusions 96367 (decadron, benadryl, zofran and iron), each documented 20 minutes to 1 hour. Since CPT code 96367 "revised" in 2012, Medicare now only allows payment on 3. Is there a new coding rule on this? Should I appeal this with Medicare? Should nursing staff adjust infusion times to bill 96375 instead?
