Billing tips

Document specifically that NO implant, mesh, or prosthetic material was used during the procedure
Impact: Prevents downcoding or denials; the distinction from 21408 (with implant) is critical for proper code selection and can mean difference of several hundred dollars in reimbursement
Clearly identify the specific orbital wall(s) treated (floor, medial wall, roof, lateral wall, or rim) in operative report
Impact: Supports medical necessity and prevents unbundling audits when multiple facial fractures are addressed; essential for modifier 59 justification
Include pre-operative and post-operative CT imaging reports with claim for complex cases or when modifier 22 is applied
Impact: Increases approval rate for modifier 22 claims by 35-40% and substantiates medical necessity for open approach versus closed reduction
Bill facility and non-facility settings at the same rate ($575.77) since both PE RVUs are identical for this code
Impact: No site-of-service differential for 21406; ensures consistent reimbursement expectations across settings
Use appropriate E/M code with modifier 25 on same date of service only if significant separately identifiable evaluation occurred
Impact: Typical pre-operative evaluation is bundled; only medically necessary distinct E/M services qualify, potentially adding $100-200 to claim
Verify global period (90 days) and avoid billing related services during postoperative window without appropriate modifiers
Impact: Prevents automatic denials for services within global period; unmodified claims for related care will be denied 100% of the time

Frequently asked questions

What is the Medicare reimbursement rate for CPT 21406 in 2025?

The 2025 Medicare national average reimbursement for CPT 21406 is $575.77 for both facility and non-facility settings. This is based on 17.8 total RVUs (7.42 work RVU, 9.01 PE RVU, 1.37 MP RVU) multiplied by the 2025 conversion factor of 32.3465.

What is the difference between CPT 21406 and 21408?

CPT 21406 is for open treatment of orbital fracture WITHOUT implant, while 21408 includes the placement of an implant, mesh, or prosthetic material. The presence or absence of implant material is the sole distinguishing factor and must be explicitly documented in the operative report.

Can CPT 21406 be billed bilaterally?

Yes, CPT 21406 can be billed with modifier 50 for bilateral orbital fracture repairs performed during the same operative session. Medicare reimburses bilateral procedures at 150% of the unilateral rate, resulting in $863.66 for bilateral repairs.

What RVU value does CPT 21406 carry?

CPT 21406 has a total RVU of 17.8, consisting of 7.42 work RVUs, 9.01 practice expense RVUs (same for facility and non-facility), and 1.37 malpractice RVUs according to the 2025 Medicare Physician Fee Schedule.

Does CPT 21406 have a global period?

Yes, CPT 21406 has a 90-day global surgical period. All routine postoperative care related to the orbital fracture repair during these 90 days is included in the reimbursement and cannot be separately billed without appropriate modifiers.

When should modifier 22 be used with CPT 21406?

Modifier 22 should be appended to CPT 21406 when the orbital fracture repair involves significantly greater complexity than typical, such as extensive comminution, difficult anatomical access, prolonged operative time, or unusual patient circumstances. Documentation must include comparison to typical procedure and justify the increased work.

Can CPT 21406 be billed with other facial fracture repair codes?

Yes, CPT 21406 can be billed with other facial fracture codes if separate distinct fractures are treated, but modifier 59 should be appended to indicate distinct procedural services. Documentation must clearly show different anatomical locations and separate surgical work to avoid bundling denials.
