CPT code 25600: Closed treatment of distal radial fracture

Found our content helpful?

Key takeaways

CPT code 25600 describes closed treatment of a distal radial fracture, or an epiphyseal separation, performed without manipulation.

Use 25600 only when nobody reduced or repositioned the fragments, because manipulation moves the claim to 25605.

The global period runs 90 days, so routine fracture follow-up inside that window is not separately billable.

Two frequent rejections come from a missing LT or RT modifier, and from billing 29125 for the same-day splint.

Practice management software like Pabau pre-fills the claim from the patient record, checks eligibility, and tracks claim status.

CPT code 25600 covers closed treatment of a distal radial fracture, such as a Colles or Smith type, without manipulation. It also covers epiphyseal separation, and it includes treatment of an ulnar styloid fracture in the same encounter.

The one qualifier that decides the code is manipulation. If the clinician repositioned the fragments, 25605 applies instead. That single word sets the claim, and 25600 brings a 90-day global period with it.

The sections below cover the code family, the modifiers, the diagnosis pairings, and the points where these claims stall.

What CPT code 25600 covers, down to the ulnar styloid

CPT code 25600 covers closed treatment of a distal radial fracture, including Colles and Smith types, plus epiphyseal separation.

If the clinician treats a fracture of the ulnar styloid during the same encounter, that work already sits inside this code. Do not report it separately. One condition runs through all of it: no manipulation is performed.

The fracture is immobilized in a splint or a cast, with no attempt to reduce or reposition the fragments.

The single question that separates 25600 from 25605

Did the clinician move the fragments? That answer picks the code, on its own. Manipulation means the provider physically repositioned the fracture to improve alignment.

CPT code 25600 applies when no repositioning happened, and 25605 applies when it did. The clinician documents that decision and the coder reports it. An imaging report cannot stand in for the statement.

Billing 25605 for a fracture the note never describes as manipulated is upcoding, and payers treat it that way. Without a clear description of the technique, expect a downcode, a denial, or a request for records.

The safer position is always the code the documentation supports.

The five codes a 25600 case can escalate into

CPT code 25600 opens a family that tracks how much intervention the fracture needed. Closed treatment sits at the front, with 25600 for no manipulation and 25605 for manipulation.

Percutaneous skeletal fixation follows at 25606, where pins or wires stabilize the fracture without opening it. Open treatment with internal fixation covers 25607, 25608 and 25609, and the fragment count decides which of the three applies.

The fragment count behind 25607, 25608 and 25609 comes from the operative note, never from a coder’s reading of the imaging. Watch the middle of the family too.

A case that goes to percutaneous fixation is no longer closed treatment, so 25606 replaces 25600 rather than joining it on the claim.

The modifiers that keep 25600 claims moving

Laterality comes first, because payers reject extremity codes that arrive without a side. The rest of the list handles bundling, repeats, and visits inside the global period.

Modifier 59 needs the most care of the six. Payers review it closely, and using it without a documented separate site or session invites a compliance review.

Check the current NCCI edits and the AAPC modifier guidance before you unbundle anything against 25600.

Where 25600 is performed changes what it pays

Medicare pays 25600 at two different rates, and the setting decides which one applies. Facility rates cover the procedure in a hospital or an ambulatory surgery center. Non-facility rates cover it in a physician office, and they run higher, because the practice absorbs the overhead itself.

For current figures, run code 25600 through the CMS Physician Fee Schedule lookup with your own locality. Geographic adjustment moves the number, so a national average is little help at the claim line. Commercial rates are negotiated separately, and they can land well above or below Medicare.

What the 90-day global period on 25600 swallows

CPT code 25600 carries a 90-day global surgery period. Under CMS rules, the surgical package covers the day of the procedure plus 90 days of related follow-up care. These services are not separately billable inside that window:

• Routine fracture follow-up visits, including cast checks and radiograph review
• Cast or splint removal by the treating physician
• Post-procedure E&M visits tied to fracture management

Plenty still gets paid inside the window. Complications that need further treatment stay billable, as do unrelated visits with modifier 24 and separate procedures on another site with modifier 59. Misreading that line produces a steady stream of avoidable denials in this code family.

The diagnosis codes that make 25600 payable

A 25600 claim needs an ICD-10-CM code that matches the note on three points: laterality, displacement, and encounter type.

The 7th character carries the encounter, with A for initial, D for subsequent care, and S for sequela. Pairing the wrong character is a routine rejection, and it is easy to catch before submission.

Pick the most specific code the note supports. Payers reject unspecified codes when the clinical note clearly states the side. Our ICD-10-CM code library lists the S52 options in full, and the CDC lookup tool confirms which 7th character each encounter type takes.

The one note entry that protects a 25600 claim

The note has to state that no manipulation was performed. That single line separates a supported 25600 from a downcoded one, and it is the entry most often left out.

The rest of the list below is standard fracture documentation, and payers expect all of it.

• Fracture confirmation: An imaging report confirming the distal radial fracture, with laterality and fracture type where possible
• Fracture characteristics: Displacement, angulation, and whether the ulnar styloid is involved
• No manipulation statement: An explicit entry stating that closed reduction was not performed
• Treatment rendered: The type of immobilization applied, the materials used, and the position of the extremity
• Patient instructions: Weight-bearing restrictions, the follow-up plan, and return precautions
• Physician signature: Treating provider attestation with the date of service

Structured note templates can carry that statement as a checkbox, so the clinician confirms it in the room. Fixing it there takes seconds. Fixing it at claims review takes an appeal.

How a 25600 claim moves from splint to payment

A 25600 claim clears five checkpoints on its way to payment, and each one has its own failure mode. Knowing where claims stall tells you which step to tighten first.

1. Encounter and charge capture. The provider documents the fracture, the immobilization, and the absence of manipulation. Charge entry picks up 25600 with LT or RT.
2. Eligibility and payer order. The front desk confirms coverage and rules out workers’ compensation or auto liability. A wrist fracture often has another carrier ahead of the health plan.
3. Scrubbing. Your scrubber checks the laterality modifier, the ICD-10 7th character, and any 29125 line that NCCI will bundle.
4. Submission and adjudication. The claim leaves as an 837P or a CMS-1500. The payer prices it against the fee schedule for that place of service.
5. Remittance and the global window. Payment posts and the 90-day clock starts. Follow-up visits inside it need modifier 24 to survive.

Can you bill 29125 for the splint on top of 25600?

Usually not. CPT 29125 covers application of a static short arm splint, and the first splint applied for the fracture belongs to the fracture care package.

Under NCCI rules, 29125 bundles into CPT code 25600 when the same physician reports both on the same date of service.

Two situations change the answer. A later encounter for recasting or splint replacement is billable, using the casting and strapping codes for that visit.

So is a splint applied for a separate condition by a provider outside the original global period. NCCI edits update quarterly, so confirm the pair before you send it.

Six mistakes that turn a clean 25600 into a denial

These six account for the bulk of 25600 denials, and each one is preventable at charge entry rather than at the appeal.

1. Upcoding to 25605 without manipulation documentation. Billing 25605 when the note never describes manipulation is an audit risk and a compliance problem. The note must state that closed reduction was performed and describe the technique. Without that, 25600 is the correct code.
2. Missing laterality modifier. Omitting LT or RT triggers rejections from payers that require a side on extremity codes. Add laterality at charge entry, not as a retroactive fix.
3. Billing follow-up visits inside the 90-day global period. Routine fracture checks billed as E&M services inside the window are denied automatically. Modifier 24 only works when the visit clearly treats something else.
4. Incorrect ICD-10 encounter suffix. Using A for a subsequent care visit, or D for an initial one, triggers a mismatch rejection. Map the 7th character to the encounter the note describes.
5. Bundling 29125 on the same claim. Adding the splint application code for the same date and the same provider creates a bundling rejection. Remove the 29125 line unless a separate service is documented.
6. Applying modifier 59 without documentation. Auditors read modifier 59 as a bundling override, so a second procedure needs a documented separate site or session behind it.

Denial management pays off fastest at the code level. Pull every denied 25600 from the last quarter and sort the reasons. The fix usually sits at charge entry rather than at the appeal desk.

Run this check before you submit

Six lines, half a minute, before the claim leaves the practice:

• The note states that no manipulation was performed, in those words.
• LT or RT sits on the 25600 line.
• The ICD-10 code matches the documented side, and the 7th character matches the encounter.
• No 29125 line rides along for a same-date splint.
• Eligibility is confirmed, and no workers’ compensation or auto carrier is primary.
• The imaging report is in the chart, and the provider has signed the note.

How claims software keeps 25600 claims clean

In a split system, the biller rebuilds each claim from the note by hand. The side, the diagnosis, and the procedure code all get retyped, and every retype is another chance to drop a modifier.

Practice management software like Pabau works from the record instead. The CPT code attached to the service lands on the charge line, and the ICD-10 slots seed from the patient’s recorded problem list.

Built-in CPT and ICD-10 lookup libraries sit behind a search icon, so a biller can confirm 25600 against 25605 without leaving the claim. Required fields have to be complete before the send button unlocks.

For US practices, Pabau’s claims software for practices submits through Claim.MD, a clearinghouse that reaches thousands of payers. Eligibility runs in real time before the claim leaves, remittances post back automatically, and claim status stays visible without a call to the payer.

Send cleaner fracture claims the first time

Pabau pre-fills the CMS-1500 from the patient record and keeps CPT and ICD-10 lookups beside the claim. US claims go out through Claim.MD, with real-time eligibility checks before they leave. Fewer retypes, fewer rejected 25600 lines.

Conclusion

CPT code 25600 is an easy code to report and an easy one to lose. The descriptor is short, but the note behind it has to say that nobody manipulated the fracture. The 90-day clock then starts the moment you bill it, and it governs every visit that follows.

So the work belongs upstream, not at the appeal desk. Put the manipulation statement in the note template, put laterality in the charge screen, and run eligibility before the patient is splinted.

Book a demo to see how Pabau moves those checks to the point of care, before a 25600 claim ever reaches a payer.
