CPT code 21386 covers the surgical repair of broken bones around the eye socket (orbit) using an open approach, where the surgeon makes an incision to access and fix the fracture. This is typically performed after facial trauma such as car accidents or sports injuries that damage the delicate bones surrounding the eye.
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
Always append modifier LT or RT to specify laterality, as Medicare requires anatomic specificity for orbital procedures
Impact: Prevents automatic denials and resubmission delays that can postpone payment by 30-60 days
Document whether internal fixation (plates/screws) was used, as this justifies the open approach versus closed treatment and supports medical necessity
Impact: Strengthens defense against downcoding to lower-paying closed treatment codes (21401) which reimburse approximately 60% less
When billing with other facial fracture repairs, ensure 21386 is sequenced correctly based on RVU values to maximize reimbursement under multiple procedure payment reduction rules
Impact: Proper sequencing can preserve an additional $200-400 per case compared to improper ordering
Verify global period (90 days) and avoid billing related E/M services without modifier 24 during the postoperative window
Impact: Prevents denials of legitimate evaluation services valued at $100-200 per visit
For complex cases requiring modifier 22, submit operative report with claim showing operative time exceeding typical 90-120 minutes and specific anatomic challenges
Impact: Can increase reimbursement by $135-200 when properly documented and approved
Confirm pre-authorization requirements for commercial payers, as many require prior approval for orbital fracture repairs to avoid full claim denial
Impact: Prevents denials of the entire $681.22 (Medicare) to $1,500+ (commercial) reimbursement
