CPT code 25606 – Distal radius fracture percutaneous fixation

Key takeaways

CPT code 25606 reports percutaneous skeletal fixation of a distal radius fracture or epiphyseal separation, with pins or wires placed through the skin.

The approach picks the code: closed manipulation is 25605, percutaneous pinning is 25606, and open treatment with internal fixation is 25607 to 25609.

Joint involvement and fragment count only matter among the open codes, so an intra-articular fracture pinned through the skin still takes 25606.

The 90-day global period bundles routine follow-up visits, cast changes, and pin removal into the surgical payment.

CPT code 25606 covers percutaneous pinning of a distal radius fracture

CPT code 25606 is defined by the American Medical Association as “Percutaneous skeletal fixation of distal radial fracture or epiphyseal separation.” The code reports fixation placed across the fracture through the skin, without open exposure of the fracture site.

In practice, the surgeon aligns the distal radius under fluoroscopy, then drives K-wires or pins through the skin and across the fracture to hold it. Any manipulation needed to reach that alignment is part of the procedure, so 25605 is not reported for the same fracture.

What 25606 includes

• Fracture site: the distal radius, including epiphyseal separation in children.
• Approach: percutaneous, with fixation placed through the skin and no open exposure of the fracture.
• Fixation: K-wires, Steinmann pins, or similar implants placed across the fracture, usually under fluoroscopic guidance.
• Fracture pattern: the descriptor sets no articular or fragment-count requirement, so extra-articular and intra-articular fractures both qualify.
• Ulnar styloid: the 25606 descriptor does not mention the ulnar styloid. If the styloid is pinned separately, 25651 describes that service, so check NCCI edits before you report both.

The approach decides which 25600-series code fits

The distal radius family splits on approach first. The closed codes, 25600 and 25605, involve no fixation through the skin, and 25606 covers percutaneous pins or wires. The open codes cover direct exposure with internal fixation.

Joint involvement and fragment count only come into play among the open codes. That is why an intra-articular fracture pinned through the skin still lands on 25606.

All six codes carry a 90-day global period in the CY 2026 CMS RVU file. The two closed codes also include closed treatment of an ulnar styloid fracture when it is performed.

Closed treatment vs percutaneous fixation: 25605 or 25606?

These two codes are the pair most often confused, because both can follow the same reduction. The deciding question is whether the surgeon placed fixation through the skin.

If the fracture was manipulated and held only with a cast or splint, bill 25605. If pins or wires were placed across the fracture, bill 25606.

The documentation rule follows from the table. The operative note for 25606 must describe the pins or wires placed and confirm the fracture was not opened. Imaging language about the joint surface supports the diagnosis code, but it does not change the CPT choice.

25606 or open treatment? How 25607, 25608, and 25609 differ

Once the surgeon opens the fracture to place internal fixation, 25606 no longer applies. The open codes then split on joint involvement and, for intra-articular fractures, on the number of fragments fixed.

Fragment count never moves a pinned fracture into 25608 or 25609. Those codes require open treatment with internal fixation, so the operative note must describe an incision and direct exposure of the fracture.

Billing 25608 for a percutaneous procedure misstates the service, and so does billing 25606 for an open plate repair. Match the code to the approach first.

Modifiers on a 25606 claim

• RT or LT: identifies the treated wrist on most payer claims.
• 50: marks a bilateral procedure. The CMS RVU file gives 25606 a bilateral indicator of 1, so Medicare pays 150% of the fee schedule amount.
• 57: goes on the E/M visit the day before or the day of surgery when that visit produced the decision to operate.
• 58, 78, and 79: mark staged procedures, unplanned related returns to the operating room, and unrelated procedures during the global period.
• 54 and 55: split the care when one surgeon operates and another manages recovery. CMS divides the payment into 10% preoperative, 69% intraoperative, and 21% postoperative care.
• 80, 81, and 82: report an assistant at surgery. CMS gives 25606 an assistant indicator of 1, so Medicare pays an assistant only when documentation establishes medical necessity.

Documentation requirements for CPT code 25606

The operative note has to support each element of the descriptor. Auditors look for proof that fixation crossed the fracture through the skin and that the fracture site was never opened.

• Fracture site and pattern: the distal radius fracture named and described, such as Colles-type, Smith-type, die-punch, Barton, or epiphyseal separation, with laterality.
• Percutaneous approach: a statement that pins or wires were placed through the skin, with no open exposure of the fracture.
• Reduction: the manipulation performed, if any, and the alignment achieved before fixation.
• Fluoroscopic guidance: a statement that fluoroscopy confirmed the reduction and guided pin placement.
• Pin details: the number, size, and entry points of the K-wires or pins, and whether they were left protruding or buried.
• Immobilization: the cast or splint applied after fixation.
• Diagnosis pairing: an ICD-10-CM code that names the fracture pattern and side, with the correct 7th character.

ICD-10 codes paired with 25606

Because 25606 has no articular requirement, it can pair with any distal radius fracture code in category S52.5. A child’s epiphyseal separation takes a physeal code from S59.2. Each code needs laterality and a 7th character.

S52.509A is a weak choice on a surgical claim. It names neither the side nor the fracture pattern, so replace it with a specific code once the imaging report allows.

At the operative encounter, 7th character A covers a closed fracture. Open fractures take B for type I or II, and C for type IIIA, IIIB, or IIIC. Verify every code in the CDC/NCHS ICD-10-CM web tool before submission.

Can CPT 25606 be billed with an external fixator code?

CPT 20690, application of a uniplanar external fixation system, may be separately reportable with 25606. Whether it is depends on the current NCCI edit for the pair, the payer, and whether the fixator was a distinct procedural step.

• When 20690 may be separately reported: the surgeon applies an external fixator for ligamentotaxis on top of percutaneous pins. Both are documented as distinct steps.
• When the combination is at risk: the external fixator is the only stabilization, and no separate pinning across the fracture is documented.
• NCCI edit status: check the current quarter’s NCCI procedure-to-procedure table for the pair, including its modifier indicator, before you bill.
• Documentation: the operative note must describe the fixator application and the percutaneous fixation as separate steps.

NCCI edits are updated every quarter. Look up the pair in the CMS NCCI procedure-to-procedure edits or your clearinghouse’s NCCI checker before submitting the combination.

Medicare reimbursement and RVUs for CPT 25606

Medicare pays about $642 nationally for CPT code 25606 in CY 2026, before geographic adjustment. The figure is the code’s 19.21 total RVUs multiplied by the $33.4009 conversion factor.

These values come from the October 2026 release of the CMS PFS relative value files. Each RVU component is then adjusted by its own Geographic Practice Cost Index, so your locality moves the number.

Use the CMS Physician Fee Schedule lookup tool to confirm the rate for your locality. Commercial payment depends on each payer contract, so check the contracted rate before you quote it.

Global period and post-operative care for CPT 25606

CPT code 25606 carries a 90-day global surgery period, with Medicare indicator 090. The surgical payment covers a defined bundle of related services before and after the procedure, and billing those services separately is a compliance risk.

What is included in the 90-day global period

• Related evaluation and management visits from the day after surgery through day 90
• Cast changes, splint applications, and dressing changes related to the fracture
• K-wire or pin removal by the operating surgeon within the 90-day window
• Minor complications managed in the office, such as pin-site checks

What can be separately billed during the global period

• Treatment of a new, unrelated condition arising after surgery
• Complications that need a return to the operating room, with modifier 78
• Staged procedures planned before the initial surgery, with modifier 58
• Services by a physician outside the operating surgeon’s group practice
• The E/M visit at which the decision to operate is made, with modifier 57 when it falls the day before or the day of surgery

A frequent global period error is a routine follow-up E/M visit billed with no modifier or no documented unrelated condition. Recording the global end date against each patient’s surgery date helps prevent duplicate billing. Your denial management workflow should include a global period check at the claim creation stage.

Common denial reasons for CPT 25606 claims

Denials on CPT code 25606 cluster around a small set of documentation and code-selection problems. Knowing the patterns makes it faster to build a prevention checklist and an appeal template.

• Approach not documented: the note does not show that fixation went through the skin. The payer then cannot tell 25606 from 25605 or an open code. Fix: describe the pins, their entry points, and the absence of open exposure.
• 25605 billed with 25606: both codes are submitted for the same fracture, though the reduction is part of the pinning procedure. Fix: report 25606 alone for that fracture.
• Wrong code for the approach: an open plate repair is billed as 25606, or a pinning is billed as 25608 or 25609. Fix: match the code to the approach in the operative note before you look at fragments.
• NCCI conflict with 20690: an external fixator code is submitted without checking the current edit or documenting distinct steps. Fix: check the pair and document both steps.
• Missing fluoroscopy documentation: some payers review whether imaging guidance was recorded for percutaneous fixation. Fix: state that fluoroscopy confirmed the reduction and guided pin placement.
• Unspecified ICD-10 code: S52.509A names neither side nor pattern, which weakens the case for surgery. Fix: code the laterality and fracture pattern from the imaging report.
• Global period errors: routine post-op visits are billed without modifiers during the 90-day window. Fix: record the global end date at the time of surgery.

For a denied claim, lead the appeal with the operative note’s description of the percutaneous fixation and the imaging that supports the diagnosis. The denial codes reference covers the CARC codes you are likely to see on a 25606 denial. The specific code tells you which appeal argument to lead with.

How claims software keeps a 25606 claim moving

Many orthopedic billers send surgical claims from one system and check their status in another. A 25606 claim that stalls at the payer can sit unnoticed for weeks before anyone follows up.

In Pabau, US claims are submitted through the Claim.MD integration. Each claim’s status is tracked after submission, so billers can see which claims were accepted, which are pending, and which were rejected.

With status-tracking claims software, your team spends less time chasing 25606 claims. That leaves more time for the coding questions that need a person’s judgment.

Conclusion

Put the approach at the top of your coding checklist for distal radius repairs, ahead of the imaging report. When the note proves pins crossed the fracture through the skin with no open exposure, 25606 holds up even on a comminuted intra-articular fracture.

The cost of that rule falls on documentation. If the note skips the pin details or the fluoroscopy statement, the payer can read the claim as 25605 or an open code. Any appeal then starts from a weaker record.

Tracking each claim after submission is part of revenue cycle management, and Pabau handles it by sending US claims through Claim.MD and following their status. Book a demo to see how that workflow fits orthopedic billing.
