CPT code 21465: Open treatment of mandibular condylar fracture

Key takeaways

CPT code 21465 covers open treatment of a mandibular condylar fracture, whatever fixation the surgeon uses.

There is no closed-treatment code specific to the condyle, so closed care is reported with 21450 or 21451.

Medicare pays the same amount in a facility and an office, because CMS marks non-facility pricing NA for this code.

Condylar-process diagnoses now need laterality, so S02.611A or S02.612A replaces the retired S02.61XA.

Practice management software like Pabau keeps operative documentation, modifiers, and global periods in one record.

CPT code 21465 reports the open treatment of a mandibular condylar fracture. It sits in the Musculoskeletal System chapter of the AMA’s CPT code set, in the Head range that runs from 21000 to 21499.

The code covers surgical access to the fracture, reduction of the condylar segment, and any plates or screws the surgeon places along the way. Fixation hardware is part of that work rather than a separate charge. What defines the code is the incision, not the hardware.

Open treatment vs. closed treatment: Choosing the right code

There is no closed-treatment code specific to the condyle. Plenty of coding round-ups cite 21460 as the closed counterpart to 21465, but 21460 is not a CPT code and never has been. Closed care of a condylar fracture is reported with the general mandibular codes, 21450 or 21451.

The operative note has to name the surgical approach to support 21465. Preauricular, retromandibular, and transparotid are the three you will see most often. A note that describes manipulation and arch bars does not support an open code, however displaced the condyle was on imaging.

That distinction decides the payment as much as the code choice does. Reconstructive teams that run structured operative templates in a plastic surgery EMR tend to clear this bar without extra effort.

The approach becomes a required field rather than something the surgeon has to remember to dictate.

2026 Medicare payment for CPT code 21465

Medicare pays about $723.80 for CPT code 21465 in 2026, before locality adjustment. The figure is the same in a hospital, an ambulatory surgical center, and an office. CMS marks the non-facility practice expense “NA” for this code, so there is no separate office rate to chase.

2026 is the first year with two conversion factors. Qualifying participants in an advanced alternative payment model are paid at $33.5675, and everyone else at $33.4009.

The difference is small on a single case, but it compounds across a busy trauma service. Our guide to Medicare billing covers how that split works across the rest of the fee schedule.

Commercial and managed care payers set their own rates against contract terms, so treat these figures as the Medicare baseline. You can confirm your own locality with the CMS Physician Fee Schedule lookup tool.

RVU breakdown for 21465

CPT code 21465 carries 21.67 total RVUs in 2026, of which 12.79 are work. The facility and non-facility columns are identical, because CMS does not price this code in an office setting. The values below come from the CMS physician fee schedule relative value files.

An “NA” in the non-facility column is a pricing instruction, not a missing value. CMS uses it for procedures it does not expect to see performed in an office. The facility figure then applies wherever the case is billed. Treat any source that shows a higher office rate for 21465 as inverted.

CMS republishes these values every January, and the work RVU has drifted down over recent cycles. It stood at 13.12 in 2024 and 12.79 in 2026. Pull the current file before you build a productivity target around it.

Modifiers and CMS payment indicators

CMS attaches payment policy indicators to every code, and they settle most modifier arguments before they start. For 21465 the bilateral, co-surgeon, and assistant indicators are all permissive, while team surgery is not.

The multiple procedure indicator is 2, so standard reduction rules apply when 21465 is billed alongside another facial repair in the same session. Tracking which modifier belongs on which case is where surgical teams lose money. Pabau’s claims management software keeps that detail attached to the treatment record instead of a side spreadsheet.

ICD-10 diagnosis codes that support medical necessity

Condylar-process fractures need a laterality code. S02.611A covers the right side and S02.612A the left, both for an initial encounter with a closed fracture. Use S02.610A only where the operative record genuinely does not state a side.

Two codes that still circulate widely are no longer valid. S02.61XA, S02.61XB, and S02.61XD were retired on September 30, 2016, when the condylar subcategory gained laterality.

S02.60XA went the same way, and its replacement is S02.609A. You can check any of these against the current ICD-10-CM code files.

Condylar and subcondylar are separate subcategories, and radiology reports use the terms loosely. If the imaging says subcondylar and the surgeon repaired the condyle, resolve it in the chart before the claim goes out. Query the surgeon rather than picking the code that matches the procedure.

Related mandibular and facial fracture codes

Mandibular fracture codes split along two axes: open versus closed, and whether interdental fixation was used. Picking the wrong sibling is a common audit trigger in oral and maxillofacial surgery, so it helps to see the family side by side.

Facial trauma rarely arrives one fracture at a time. A condylar repair often sits on the same operative note as work on the orbit or the midface. That brings 21407 and 21365 into the same claim.

Frontal sinus involvement adds 21343 to the picture. Sequence the highest-valued code first and let the multiple procedure rules reduce the rest, rather than leaving the payer to guess at the primary procedure.

Groups that also bill musculoskeletal repairs in a sports medicine practice will recognize the same sequencing logic.

Billing guidelines and documentation requirements

Accurate billing for 21465 starts in the operating room. What the surgeon dictates on the day decides whether the claim survives a review months later.

• Name the approach. Record whether the access was preauricular, retromandibular, or transparotid, along with the degree of displacement and the reduction technique. Note the type and number of fixation devices if any were placed.
• Say why, if there was no fixation. Open treatment stands on its own without hardware. A note that shows an open approach and no fixation still supports the code, provided the surgeon explains the clinical reasoning.
• Match the place of service. Hospital outpatient is POS 22, inpatient is POS 21, and an ambulatory surgical center is POS 24. Because CMS does not price this code in an office, an office place of service on a 21465 claim invites a review.
• Check NCCI edits. Run the code pair through the National Correct Coding Initiative edits before billing adjacent facial procedures on the same claim.
• Respect the 90-day global period. Post-operative visits inside that window belong to the surgical fee. Only a new and unrelated problem is billed separately, and the note has to show it.

Global periods catch practices out most often when a patient transfers between surgeons mid-recovery. The same applies to other 90-day surgical codes such as 19316, where the post-operative split has to be agreed in writing before either party bills.

Enrollment details matter too, since a claim under the wrong billing arrangement is denied before anyone reads the operative note. Our guide to the Medicare provider number covers what has to be on file for a surgical group.

Teams still working from scanned paper carry the most risk here. An illegible dictation cannot show the surgical approach, and that single omission turns an open code into a denial.

Structured medical forms and typed operative records remove the argument entirely, and they also make HIPAA compliance easier to demonstrate at audit.

How Pabau keeps surgical documentation and billing in one place

Most surgical billing problems are handoff problems. Think about where the detail for a single condylar repair usually sits.

• The surgical approach is buried in a dictation
• The fixation detail is in the surgeon’s head until someone asks
• The modifier decision sits in the biller’s inbox
• The global period lives with whoever remembers the date

Each handoff is a chance for something to drop, and a dropped detail on this code costs about $724.

Practice management software like Pabau removes those handoffs by keeping the whole case in one client record. The appointment, the consent, the operative note, the photographs, and the invoice all sit against the same patient. The person coding the claim can see what the surgeon actually did.

That matters most on codes like 21465. One missing sentence about the approach is the difference between payment and a denial. Structured forms turn the approach into a field, and reporting shows which codes are being denied and why.

Pabau’s patient management software ties the clinical and financial sides of a case together. Its digital forms capture pre-operative assessments in a format a payer can follow.

Every Pabau subscription includes every feature, so a two-surgeon practice gets the same reporting and documentation tools as a multi-site group. The practice management software overview walks through how those pieces fit together for a surgical team.

Conclusion

If you take one thing from this page, make it the open-versus-closed test. There is no condyle-specific closed code, so the incision in the operative note is what earns 21465 and its 21.67 RVUs. Everything else follows from that sentence in the chart.

The trade-off worth remembering is that this code rewards documentation discipline rather than clinical complexity. A straightforward repair with a clear approach note gets paid. A difficult one with a vague note does not, and the appeal costs more than the difference.

Fix that at the point of dictation and the rest of the billing cycle gets quieter. Book a demo to see how Pabau keeps operative documentation, modifiers, and global periods together for oral and maxillofacial surgery teams.
