CPT code 23500 – Closed clavicle fracture treatment without manipulation

Key takeaways

CPT code 23500 covers closed treatment of a clavicle fracture without manipulation, meaning conservative care with no reduction performed.

A 90-day global period applies, so routine follow-up visits, sling checks, and dressing changes are bundled and not billed separately.

Pair 23500 with an ICD-10 S42.0- code, and check laterality and the 7th character, since a wrong encounter suffix is a common denial trigger.

Use CPT 23505 when closed reduction is performed and CPT 23515 for open treatment, based on what was done, not fracture severity alone.

Pabau’s claims management software pre-fills 23500 claims from the patient record and checks required fields. It adds CPT and ICD-10 lookup libraries, Claim.MD submission, eligibility checks and ERA posting.

CPT code 23500 covers closed clavicle care without reduction

CPT code 23500, as defined by the American Medical Association, reads: Closed treatment of clavicular fracture; without manipulation. It sits in the Musculoskeletal System section of CPT, inside the Shoulder subsection (23000-23929).

Orthopedic surgeons, emergency physicians and primary care providers all bill it when they treat a clavicle fracture conservatively. The code fits only when the clinician decides not to manipulate the fracture. That decision has to be written in the note, because a payer won’t infer it.

23500 fits fractures that need a sling, not a reduction

Closed treatment without manipulation means nobody moves the bone fragments. It suits non-displaced or minimally displaced midshaft fractures where the alignment is already acceptable.

The clavicle is one of the most commonly fractured bones, and roughly 80% of clavicle fractures occur at the midshaft. Most of them heal well with conservative care.

These clinical criteria support coding to 23500:

• Imaging (X-ray) confirms a clavicle fracture with acceptable alignment
• No significant shortening, angulation, or displacement that needs reduction
• The treating physician documents the assessment and the decision not to manipulate
• An immobilization device is applied, such as an arm sling, figure-of-eight bandage, or clavicle strap
• A follow-up plan is documented, typically with repeat imaging at one to two weeks

If the clinician performs any manual reduction, even a brief attempt, the code shifts to 23505. Don’t choose between the two on fracture grade alone. The note has to describe what was done, not just what was found.

One reduction attempt turns 23500 into 23505

Only one clinical act separates CPT 23500 from CPT 23505, and that act is manipulation. With no reduction, 23500 applies. When the physician performs a closed reduction to move the fragments into better alignment, 23505 is correct.

Example: An ED physician briefly tries to reduce a midshaft fracture, then decides a sling is enough. Because the attempt is documented, the claim goes out as 23505, not 23500. The documentation drives the code, not the final treatment alone.

The ICD-10 code for 23500 must name the site, side and encounter

Every CPT code 23500 claim needs an ICD-10-CM diagnosis from the S42.0 subcategory (fracture of clavicle). The 5th character gives the location, and the 6th gives displacement and laterality. The 7th character gives the encounter type, and getting it wrong is a common reason these claims are denied.

For superbill documentation and claim submission, pick the S42.0 code that matches the imaging report:

7th character guidance: Use A (initial encounter) on the visit where active treatment starts, which is when 23500 is billed. Use D (subsequent encounter) for routine healing visits, which fall inside the global period. Later visits for delayed healing take G, as in S42.002G for a left clavicle. Nonunion takes K, and malunion takes P.

Documentation for 23500 has to prove what didn’t happen

Building a clean claim for CPT code 23500 starts with the clinical note. Payers audit fracture care closely because the 23500 versus 23505 split depends on documentation alone. No image or report can prove that manipulation did not occur.

Every note should carry these elements:

• Imaging report: An X-ray confirming the diagnosis, fracture location, and displacement status
• Fracture assessment: A plain description of alignment, for example “non-displaced midshaft clavicle fracture with acceptable alignment”
• Treatment rationale: Why manipulation was not performed, for example “alignment acceptable, closed treatment without manipulation indicated”
• Immobilization device: The device applied (sling, figure-of-eight, or clavicle strap) and the instructions given
• Follow-up plan: A scheduled reassessment date, typically with repeat imaging at one to two weeks
• Neurovascular check: Distal pulses, sensation, and motor function, which support medical necessity

Same-day E/M billing needs care. Because 23500 carries a 90-day global period, Medicare expects modifier 57 on the E/M where the decision to treat the fracture is made.

Modifier 25 doesn’t fit that visit. A same-day E/M for an unrelated problem takes modifier 25 instead. Some payers don’t allow a separate E/M with non-manipulative fracture care at all, so check the payer’s policy first.

The 90-day global period bundles routine fracture follow-up

CMS assigns CPT code 23500 a 90-day global period under the Medicare Physician Fee Schedule. The package covers the treatment day and the 90 days after it. The chart below shows what stays billable inside that window.

Bundled (not billed separately during the global period):

• Routine follow-up visits related to the fracture
• Sling adjustments and checks
• Dressing changes
• Removal of any temporary immobilization device

Separately billable during the global period (with documentation):

• Treatment of a new, unrelated condition, with a different diagnosis code
• E/M for a problem clearly unrelated to the clavicle fracture
• Diagnostic imaging (X-rays), billable with the appropriate imaging code
• Supplies billed with the appropriate HCPCS code and modifier
• Treatment of a complication that requires a new clinical decision, such as a nonunion coded with 7th character K

A follow-up clavicle film, for instance, is reported with CPT 73000 rather than folded into the 23500 fee.

Watch the handoff between providers. The ED often identifies the fracture, and an orthopedic surgeon takes over conservative care at a follow-up visit. When the surgeon bills 23500 at that visit, the global period runs from that date. The ED evaluation is a separate encounter under a different provider, so it isn’t bundled.

How a 23500 claim moves from encounter to payment

Most 23500 claims pass through the same six steps. Knowing where each one can stall makes a denial much easier to trace.

1. Encounter: The physician documents the imaging, the alignment, the decision not to manipulate, and the device applied.
2. Coding: The coder assigns 23500, an S42.0- diagnosis with 7th character A, and any modifier a same-day E/M needs.
3. Charge entry: The date of service goes on the charge line, and the global period is counted from it.
4. Scrubbing and submission: The claim is checked for missing fields, then sent through a clearinghouse as an electronic 837P claim.
5. Adjudication: The payer returns an 835 remittance with the payment, or with CARC codes explaining a denial.
6. Follow-up visits: Many practices log in-global visits with CPT 99024, a no-charge code that records the visit without billing it.

Steps two and four are where a wrong suffix or a blank field can stop the claim before a payer ever reviews it.

Before you submit a 23500 claim, run this checklist

A quick check before submission costs far less than an appeal. Compare each item against the note and the imaging report:

• The note says no manipulation was performed or attempted.
• Imaging confirms the fracture site, and the report is on file.
• The ICD-10 code matches the site, displacement, and side on the X-ray report.
• The 7th character is A on the initial treatment visit.
• Any same-day E/M carries the right modifier and its own documentation.
• Eligibility is confirmed, and prior authorization is on file where the payer requires it.

Medicare pays 23500 from three RVU components

Medicare reimbursement for CPT code 23500 comes from the Medicare Physician Fee Schedule (MPFS), which CMS updates every year. Three RVU components set the rate: work, practice expense, and malpractice. They’re multiplied by the annual conversion factor and a geographic adjustment.

Rates change every year and vary by locality, so check current amounts in the CMS Physician Fee Schedule lookup tool. The FastRVU 2026 RVU lookup gives a quick facility and non-facility breakdown by locality. Avoid quoting a fixed dollar figure in documentation or patient materials, because the rate resets each January 1.

Commercial payer rates for 23500 vary widely. Compare each contract against Medicare, and flag any that pay less. A real-time eligibility check before the visit also catches coverage problems that would otherwise delay payment.

Most 23500 denials trace back to a few fixable errors

Denials for CPT code 23500 cluster around a few predictable problems. These are the encounter suffix, missing imaging, the 23500 versus 23505 choice, and E/M bundling. Good denial management workflows catch them before submission.

Remittance codes tell you which of these errors hit the claim, and medical billing denial codes explains each one. The fastest fix is usually the encounter suffix. A corrected claim with the right 7th character typically passes on resubmission without extra documentation.

Adjacent shoulder codes share the 23500-23680 range

Clavicle fracture claims often sit next to other shoulder codes in the 23500-23680 range. Knowing where 23500 fits prevents mix-ups on multi-injury claims. The AAPC Codify CPT lookup lists the full range with descriptors.

Acromioclavicular (AC) joint dislocations (23540, 23545, 23550) often appear alongside clavicle fractures in trauma patients. When both are present, code each one separately with its own ICD-10 code. A proximal humerus fracture treated without manipulation is a different bone again, billed as CPT 23600.

How Pabau keeps 23500 claims complete before they go out

Orthopedic and musculoskeletal practices billing 23500 often send claims with a blank field that only shows up later as a rejection. Pabau, the practice management platform we build, checks that required claim fields are complete before the claim is sent.

Pabau’s medical billing software pre-fills claims from the patient record and submits them through Claim.MD’s clearinghouse. Coders get CPT and ICD-10 lookup libraries plus required-field validation before the Send button unlocks. ERA remittances return CARC denial reasons, so billing staff can act on rejections the day they arrive.

Real-time eligibility checks are included too. Your team can confirm a patient’s coverage for fracture care before the visit rather than after it.

Send complete 23500 claims the first time

Pabau pre-fills claims from the patient record and checks required fields before sending. It submits through Claim.MD with eligibility checks and ERA posting, so your team spends less time on rework.

Conclusion

Treat every 23500 claim as a documentation claim first. When the note says plainly that no manipulation happened, names the device, and matches the imaging, the right code follows.

The trade-off worth remembering sits in the global period. 23500 pays once for 90 days of routine care, so bill the imaging and unrelated visits that fall outside the package, and leave the rest.

If your team keeps reworking the same fracture claims, claim-field validation and clearinghouse submission cut that rework at the source. Book a demo to see how Pabau handles fracture care claims from encounter to payment.
