CPT code 25676: Open treatment of distal radioulnar dislocation

Key takeaways

CPT code 25676 describes open treatment of distal radioulnar dislocation, acute or chronic, through a surgical incision rather than external manipulation

The code is routinely confused with CPT 25660, which covers closed treatment of a radiocarpal or intercarpal dislocation at a different joint

CPT 25675 is the closed counterpart at the same joint, and the payment gap between the two widens in the facility setting

Because the descriptor covers chronic cases, the chart must state the injury date and any earlier treatment, which drives the ICD-10 seventh character

Practice management software like Pabau links procedure codes to the operative note, so coders can confirm the approach before the claim goes out

CPT code 25676 describes open treatment of distal radioulnar dislocation, acute or chronic. The AMA’s CPT code set places this code in the Musculoskeletal System chapter under Surgery. It sits in the forearm and wrist fracture and dislocation series, codes 25500 through 25695.

“Open” means the surgeon exposes the distal radioulnar joint through an incision to reduce and stabilize it. The “acute or chronic” wording widens the code further. One code carries both the fresh traumatic dislocation and the long-standing joint that never held after earlier treatment.

The distal radioulnar joint sits where the ulnar head meets the sigmoid notch of the radius. It carries forearm rotation. The triangular fibrocartilage complex (TFCC) and the interosseous membrane do most of the work holding it together. When those stabilizers fail, the ulnar head displaces dorsally or volarly.

Clinical indications: When to use this code

CPT 25676 applies when the surgeon opens the distal radioulnar joint to reduce and stabilize a dislocation. The presentation can be acute or chronic. What triggers the code is the open approach, not the age of the injury.

Orthopedic and hand surgery practices bill this code most often, usually in a hospital or ambulatory surgery center (ASC). It also appears in sports medicine practices that manage forearm rotation injuries. Post-operative rehabilitation then runs through physical therapy, inside the 90-day global window.

• Irreducible acute DRUJ dislocation: Soft tissue blocks the reduction, commonly an entrapped extensor carpi ulnaris tendon or a displaced TFCC
• Failed closed reduction: The joint reduces and immediately re-displaces, or post-reduction imaging shows it never seated properly
• Chronic or recurrent DRUJ instability: A dislocation missed at presentation, or one that stayed unstable after earlier treatment, addressed through an open approach
• Open dislocation: A wound communicating with the joint requires exposure for debridement and stabilization
• DRUJ instability alongside a distal radius or ulnar styloid injury: Reportable when the DRUJ work is distinct from the fracture repair, subject to NCCI edits

CPT 25676 does not apply when the joint is reduced without an incision. Closed reduction with manipulation is CPT 25675. Percutaneous pinning without open exposure is CPT 25671. A radiocarpal or intercarpal dislocation is a different joint entirely, coded 25660 when treated closed and 25670 when treated open.

Documentation requirements for CPT code 25676

Missing documentation is the primary reason CPT 25676 claims are denied on first submission. The chart must establish medical necessity for an open approach and confirm what was actually done inside the joint. Robust HIPAA-compliant record-keeping is also the foundation of a payable claim, not only a compliance obligation.

Use digital intake forms to capture mechanism of injury, injury date, prior treatment, and consent before the case begins. The operative note itself must include all of the following elements:

• Joint identified: Name the distal radioulnar joint explicitly, and state the direction of displacement of the ulnar head, dorsal or volar
• Acute or chronic: Record the injury date, any earlier reduction attempts, and how long the joint has been unstable
• Indication for the open approach: Say what blocked or defeated closed reduction, and cite the imaging that showed it
• Surgical approach: Describe the incision and the interval used. Name the structures exposed or protected, such as the extensor carpi ulnaris tendon and the dorsal sensory branch of the ulnar nerve
• Reduction and fixation: State how the joint was reduced, then name what held it. Options include K-wires, a radioulnar transfixion screw, suture anchors, or no hardware at all
• Soft tissue work: Note any TFCC repair or reattachment, since separately reportable repair work needs its own description
• Stability testing: Document that the DRUJ was tested through pronation and supination after fixation, plus the neurovascular status of the hand
• Laterality: Left or right side, to support modifier -LT or -RT on the claim

Post-operative imaging confirming reduction is a clinical expectation here, though documentation mandates vary by payer. Verify requirements against each payer’s local coverage determination (LCD) or medical policy before submission. The records that satisfy billing compliance are the same ones that show the diagnosis supported medical necessity.

CPT code 25676 modifiers

Selecting the correct modifier prevents downcoding, bundling edits, and denials. CPT 25676 carries a 090 global period, so post-operative visits inside that window usually do not support a separate E/M code.

Modifiers ride in item 24D, whether the claim goes out on a CMS-1500 form or its electronic equivalent. The table below covers the modifiers most frequently applied to this code.

NCCI bundling rules decide whether 25676 can be billed with distal radius fixation codes such as 25607 through 25609. Check the current CMS NCCI edit files before billing multiple codes on the same date.

ICD-10 codes used with CPT 25676

The diagnosis code must establish medical necessity for open treatment of the distal radioulnar joint. Acute presentations sit in the S63.01 subcategory of ICD-10-CM. Use the AAPC CPT-to-ICD-10 crosswalk to confirm which diagnosis codes pair with CPT 25676 for your payer.

Laterality and the episode-of-care character are required on every trauma code. A clean claim depends on both being right the first time.

The “acute or chronic” wording in the descriptor splits diagnosis coding in two directions. An acute dislocation takes an S63.01 code with seventh character A for the initial encounter. A case treated long after the original injury usually takes seventh character D or S instead.

An M25.33 instability code may fit better, depending on how the surgeon frames it. Billing a chronic reconstruction with seventh character A is a common audit finding.

RVU values for CPT 25676

Relative value units (RVUs) determine how CMS calculates payment. Every CPT code carries a work RVU (wRVU), a practice expense RVU (PE RVU), and a malpractice RVU (MP RVU).

PE RVUs differ between facility and non-facility settings because overhead costs differ. Use the FastRVU lookup tool to confirm current figures, which CMS updates annually.

RVU values for CPT 25676 are confirmed annually in the Medicare Physician Fee Schedule final rule, typically published each November. CMS also adjusts the conversion factor (CF) each year, so the dollar value of the same RVU total shifts even when the components hold steady.

Always pull current values from the CMS Physician Fee Schedule lookup tool rather than relying on third-party references for payment calculations.

The distance between the open and closed codes at this joint depends on the setting. In the non-facility setting, the two total RVUs sit within a few percent of each other.

In the facility setting, where most 25676 cases are performed, 25676 runs around 20 percent above 25675. Confirm both figures in the current fee schedule before you model the difference.

CPT code 25676 fee schedule and Medicare reimbursement

Medicare reimbursement for CPT 25676 is calculated as Total RVUs x Geographic Practice Cost Index (GPCI) x Conversion Factor. Because GPCI multipliers vary by locality, a practice in Manhattan receives a different payment than one in rural Mississippi. Pull rates directly from CMS rather than relying on estimates published by third-party sites.

Four variables move the payment on a CPT 25676 claim:

• Facility vs. non-facility rate: Most 25676 cases run in a hospital or ASC. The professional claim then receives the facility rate, and the institution bills facility costs separately. A non-facility rate applies only when the practice itself bears the overhead.
• GPCI adjustment: CMS applies three GPCI multipliers (work, PE, malpractice) based on the MAC locality. High-cost urban markets have GPCI values above 1.0. Rural markets typically fall below 1.0.
• Conversion factor: CMS sets an annual conversion factor, roughly $32 to $34 per RVU in recent years. Verify the current year’s figure via CMS before billing.
• Private payer contracts: Commercial rates for CPT 25676 vary widely by payer and contract. Many commercial payers reference Medicare rates as a base percentage, often 110% to 130% of Medicare.

Practices billing CPT 25676 across several locations should track reimbursement by MAC locality. That shows whether geographic differences explain a revenue discrepancy. Practice management software like Pabau reports claim performance by procedure code, which makes the comparison straightforward across sites.

CPT 25675 vs CPT 25676: Key differences

CPT 25675 and CPT 25676 describe the same joint but a different approach. 25675 is closed treatment with manipulation. 25676 is open treatment. The deciding question is whether the surgeon made an incision to reach the distal radioulnar joint.

CPT 25671 sits between the two. It covers percutaneous skeletal fixation of a distal radioulnar dislocation, where pins go in through the skin without an open exposure. Coding 25676 for a percutaneous case overstates the approach, and coding 25671 for an open case understates it.

The same three-way split appears elsewhere in the upper limb, as with 24582 at the humeral condyle. The operative note’s description of the exposure settles which code applies.

Related codes in the 25660-25695 range

The dislocation codes in the forearm and wrist series are organized by joint first, then by approach. Missing the joint causes most misassignments here, because 25660 and 25676 look adjacent but describe entirely separate anatomy.

That same joint-then-approach split runs through the shoulder codes, where 23620 covers closed treatment covers closed treatment of a greater tuberosity fracture. Nearby forearm and wrist codes describe different work again, such as 25310 for tendon transfer.

Note what the range does not contain. There is no code for closed treatment of a distal radioulnar dislocation without manipulation. If the joint was splinted with no reduction attempted, the service falls to an E/M code plus any applicable casting or strapping code.

Global period and post-operative care

CPT 25676 carries a 090 global period. That covers one preoperative day, the day of surgery, and the following 90 days. Routine wound checks, splint or cast changes, and scheduled follow-up visits inside that window are already paid for in the surgical fee.

Temporary K-wires or a transfixion screw are usually removed at four to eight weeks, which lands inside the global period. A planned removal of that hardware is generally part of the package rather than a separate service. An unplanned return to the operating room for recurrent instability or hardware failure takes modifier -78.

Two E/M modifiers matter here. Modifier -24 supports an unrelated E/M visit during the global period. Modifier -25 supports a significant, separately identifiable E/M service on the day of surgery. Without one of them, the E/M line is denied or recouped later.

Where the operating surgeon hands follow-up to another practice, split the global package with modifiers -54 and -55. Each practice then bills only the share of the work it did.

Common billing errors and denial reasons

Most denials for CPT 25676 fall into a handful of categories. Practices that track denial reasons by code can see which one keeps recurring and fix the upstream documentation workflow. Structured denial management turns that pattern into a fix list rather than a rework queue.

• Wrong joint coded: 25676 is assigned to a radiocarpal or intercarpal dislocation, which belongs to 25660 closed or 25670 open. This is the single most frequent error on this code. Fix: Make the joint name a mandatory field in the procedure note template.
• No stated reason for the open approach: The note records an incision but never explains why closed reduction failed or was not attempted. Payers read that as an unsupported escalation. Fix: Require an indication field naming the block or the failed reduction.
• Acute and chronic mismatch: A reconstruction performed months after the injury is billed with ICD-10 seventh character A. The diagnosis then contradicts the clinical timeline. Fix: Pull the injury date into the claim scrub and validate the seventh character against it.
• Unbundling with distal radius fixation: Billing 25676 with 25607 through 25609 on the same side triggers NCCI review. Fix: Check the specific code pair before submitting, and append modifier -59 only when the DRUJ work was genuinely distinct.
• Missing laterality modifier: Submitting without -LT or -RT causes rejection or manual review at many payers. Fix: Billing system rules should flag any 25676 claim without a laterality modifier before it leaves the practice.
• Global period E/M conflicts: Billing a separate E/M visit inside the 90-day window without modifier -24 or -25 leads to denial or recoupment. Fix: Train billers to check the global period before adding any E/M code.

How claims management software supports CPT 25676 billing

An open DRUJ case leaves a paper trail in the intake record, the operative note, and the claim. When those live in separate systems, the link between them breaks. Coders end up reconstructing the approach and the fixation from a phone call, days after the case.

Pabau keeps the procedure code attached to the note that supports it. Structured note templates carry mandatory fields for the joint, the approach, the fixation used, and laterality. The elements a payer asks for are captured before anyone builds the claim. Our Claim.MD integration then submits and tracks the claim from that same record.

Denials come back to the same place they left from. Billing staff can filter claims performance by procedure code to see whether 25676 rejections cluster around documentation or bundling. That tells you which template to fix, so the next ten claims go out clean.

Keep billing and documentation in one place

Pabau links procedure codes to clinical notes at the point of care. Coders can confirm the joint, the surgical approach, the fixation used, and the laterality in one record before the claim goes out.

Conclusion

The two most consequential words in the descriptor are “acute or chronic.” One code covers a same-week trauma reduction and a reconstruction years after the original injury. That breadth puts the weight on the operative note, which is what decides whether a claim survives review.

Before anything else, confirm the joint. CPT 25676 is the distal radioulnar joint. If the note describes the radiocarpal or intercarpal joint, the correct code is 25660 or 25670, and no modifier repairs that choice.

In a facility, where most of these cases run, the open code carries clearly more value than the closed one. So the approach recorded in the note decides the audit outcome and the payment together.
