Cltx mndblr/max alv ridge fx
CPT code 21440 covers the treatment of a broken jaw or upper jaw bone (specifically the alveolar ridge, where teeth sit) using closed reduction techniques without surgery. This involves realigning the fractured bone segments and stabilizing them, typically with wiring or splinting.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Bill in the non-facility setting when performed in an office or ASC to capture the full $725.53 reimbursement versus $581.27 facility rate
Impact: Increases revenue by $144.26 per case (24.8% higher payment)
Document the specific anatomical location (mandible vs maxilla) and whether the fracture involves displacement requiring reduction, as this justifies 21440 over less complex codes
Impact: Prevents downcoding to lower-valued treatment codes that may pay $200-300 less
Separately bill for any imaging performed on the same day (panoramic radiographs, CT scans) with modifier 59 or XU if medically necessary and documented as distinct
Impact: Can add $50-250 in additional reimbursement depending on imaging modality
When interdental wiring or arch bars are applied, ensure documentation specifies this was integral to the fracture reduction, not a separate procedure
Impact: Prevents unbundling denials and rebilling delays averaging 30-45 days
Submit claims within 24-48 hours of service with complete operative notes attached for fracture cases to expedite payment and reduce review holds
Impact: Reduces payment turnaround time from 45-60 days to 14-21 days
For bilateral fractures, verify payer-specific modifier 50 policy; some payers require two line items with RT/LT instead of modifier 50
Impact: Ensures proper bilateral payment of approximately $1,088 versus single-side $725.53
