Billing tips
Document the specific type of skeletal fixation used (K-wires, mini-plates, external fixation device) with catalog numbers when applicable
Impact: Reduces denial risk by 65% compared to vague operative notes; skeletal fixation documentation is required to justify 21330 vs lower-paying 21325
Separately report any septoplasty (30520) or turbinate reduction performed during the same session if medically necessary and documented as distinct procedures
Impact: Can add $200-400 in additional reimbursement when properly documented with modifier 59, but requires clear medical necessity documentation
Bill on the date of service when procedure is performed, not the injury date, and ensure global period tracking begins correctly
Impact: 21330 carries a 90-day global period; incorrect dating can trigger automatic denials for related E/M services worth $75-200 each
For procedures requiring general anesthesia, verify anesthesia team bills separately using base units plus time rather than care team model
Impact: Prevents coordination of benefits issues that delay payment by 30-45 days on average
Appeal denials that downcode to 21325 (closed treatment) by submitting operative report highlighting incision locations and fixation hardware placement
Impact: Successful appeals recover $180-240 difference between 21325 and 21330 reimbursement rates
For Medicare patients, verify that skeletal fixation supplies are included in facility payment rather than billed separately under HCPCS codes
Impact: Prevents compliance risk from duplicate billing; facility supply charges are bundled into the $521.75 facility rate
