ICD code S62.036B – Nondisplaced proximal scaphoid fracture, unspecified wrist

Key takeaways

S62.036B covers a nondisplaced proximal-third scaphoid fracture of an unspecified wrist at the initial encounter for an open fracture. Use S62.034B for the right wrist and S62.035B for the left.

In category S62, seventh character B means any open fracture at the initial encounter. Wrist and hand codes have no Gustilo split, so S62.036C does not exist.

The record must describe a wound that communicates with the fracture. A fracture not documented as open is coded as closed, which makes it S62.036A.

An open scaphoid fracture that reaches surgery almost always has a documented side. Check the operative, radiology and emergency notes before you settle on the unspecified code.

Practice management software like Pabau runs validation checks on every claim before it goes out, so missing details surface before a payer rejects the claim.

ICD-10 Code S62.036B: Code anatomy and quick-reference table

ICD-10 Code S62.036B is the billable ICD-10-CM code for a nondisplaced fracture of the proximal third of the scaphoid in an unspecified wrist.

It applies at the initial encounter for an open fracture, and it is valid for fiscal year 2026. The code belongs to category S62, fracture at wrist and hand level, in Chapter 19 (Injury, Poisoning and Certain Other Consequences of External Causes).

Each character in S62.036B carries a distinct clinical meaning. Misreading any one of them produces a different billable code, usually one that does not match the operative report.

Understanding the seventh character B in S62.036B

The seventh character B marks the initial encounter for an open fracture. The ICD-10-CM Official Guidelines for Coding and Reporting (Section I.C.19) define “initial encounter” as the period of active treatment. Every visit while the patient receives active treatment for the fracture counts, including surgery on any date. The subsequent-encounter characters apply only once active treatment ends and the patient is in the healing or recovery phase.

Category S62 uses a shorter seventh-character set than the long-bone fracture categories. Radius and ulna (S52), femur (S72) and lower leg (S82) codes use the Gustilo type to choose between B and C for an open fracture. Wrist and hand codes don’t, so every open S62 fracture takes B at the initial encounter. The full set for the S62.036 code family is shown below.

Why the Gustilo grade doesn’t change S62.036B

Surgeons often grade open fractures with the Gustilo-Anderson classification, which scores wound size, contamination and soft-tissue damage. That grade decides between seventh characters B and C on radius, femur and tibia fractures. It has no effect on an S62 code. A small Type I puncture and a contaminated Type III wound over the scaphoid both code to S62.036B at the initial encounter.

Coders who carry the long-bone rule over to the wrist end up searching for S62.036C, a code that doesn’t exist. What the claim does need is proof that the fracture is open. The note must describe a wound that communicates with the fracture site, such as a laceration or puncture over the break. If the record never says whether the fracture is open or closed, Guideline I.C.19.c.1 directs you to code it as closed, which is S62.036A.

S62.036B vs neighboring codes: How to choose correctly

S62.036B sits within a tightly grouped family of codes that differ by a single dimension — laterality, displacement status, open vs closed, or encounter type. An error in any one dimension produces a code that will not match the supporting documentation and may trigger a payer edit or denial. The laterality split is simple. S62.034 is the right wrist, S62.035 the left, and S62.036 an unspecified wrist.

When to use S62.036B instead of a side-specific code

The sixth character 6 in S62.036B means the record doesn’t say which wrist is fractured. Section I.B.13 of the ICD-10-CM Official Guidelines tells coders to assign the unspecified side only when the medical record doesn’t identify it. The injury S62.036B describes is the same one S62.034B and S62.035B describe. Only the documentation of the side is missing.

In practice, an open scaphoid fracture that reaches surgery almost always has a documented side. Before you settle on S62.036B, check these sources in order:

• Operative report: The procedure header and findings usually name the operative side. If it says right, assign S62.034B; if it says left, assign S62.035B.
• Radiology report: Wrist X-ray and CT reports state the imaged side in the study title.
• Emergency department note: The wound assessment normally records where the laceration sits.
• Provider query: If none of these names the side, query the treating provider. Use S62.036B only when the answer still leaves laterality undocumented.

Many payers scrutinize unspecified-laterality codes more closely, and some edit them out on surgical claims. A documented side that never made it onto the claim is one of the easiest denials to prevent.

The three checks below run in the order a coder meets them in the chart, and each one narrows the S62.03- family.

Excludes notes and coding conventions for S62 fractures

Category S62 carries one Excludes1 note and one Excludes2 note. An Excludes1 condition is never coded alongside S62.036B for the same injury. An Excludes2 condition isn’t part of the S62 code, so it gets its own code when the patient has both.

• Excludes1: Traumatic amputation of wrist and hand (S68.-). Code the amputation instead of the fracture.
• Excludes2: Fracture of distal parts of ulna and radius (S52.-). A distal radius fracture sustained alongside the scaphoid fracture gets its own S52 code.
• Pathological fractures: A scaphoid fracture caused by disease rather than trauma belongs in category M84.4-, not S62. The note must record a traumatic mechanism to support S62.036B.
• Coding defaults: Guideline I.C.19.c.1 codes a fracture not documented as open or closed as closed. A fracture not documented as displaced or nondisplaced is coded as displaced.
• Open wound: Don’t add a separate S61 open-wound code for the wound over the fracture. Seventh character B already captures it, and S61 excludes open fractures of the wrist and hand.
• External cause: Chapter 19 directs you to add a Chapter 20 code (V00-Y99) that records how the injury happened.
• Aftercare: Aftercare Z codes such as Z47.- aren’t used for injuries. Follow-up care after active treatment uses the injury code with a subsequent-encounter character, such as S62.036D.

Documentation requirements for S62.036B

Auditors reviewing S62.036B claims look for six specific documentation elements. When one is missing, payers can deny the claim or recoup the payment later. Confirm all six before you assign the code, rather than after the claim goes out. A superbill that pre-populates these fields from the operative note reduces the risk of a missed element at charge entry.

• Laterality check: S62.036B is correct only when no note identifies the injured wrist. If the operative report, radiology report, or clinical note names the right or left side, assign S62.034B or S62.035B instead.
• Proximal third location: Imaging or surgical findings must place the fracture in the proximal third of the scaphoid, not the waist or distal pole. Radiologist report language matters here.
• Nondisplaced status: Imaging documentation must describe the fracture as nondisplaced or confirm no measurable gap or step-off between fragments. If the radiologist uses “minimally displaced,” the coder should query the surgeon before assigning a displacement code. A report that never states displacement defaults to displaced, which is S62.033B.
• Open wound: The emergency or operative note must document an open wound communicating with the fracture. A description of wound size, skin laceration, or puncture supports this. Surgical incision alone does not constitute an open fracture.
• Traumatic mechanism: The note records how the injury happened. That supports the Chapter 20 external cause code and rules out a pathological fracture.
• Initial encounter designation: The encounter must fall within the active treatment phase. If the patient is returning for routine cast check during healing, the correct seventh character is D, not B.

CPT codes commonly paired with S62.036B

CPT code selection for a proximal scaphoid fracture depends entirely on what the surgeon performed. The ICD-10 code describes the diagnosis, while the CPT code describes the service. Open fractures coded to S62.036B usually pair with open surgical treatment and debridement of the fracture site. Check each descriptor in our CPT code library before charge entry.

Sending CPT and ICD-10 pairs through a clearinghouse lets it check the pairing against payer edits before the claim reaches the insurer. That catches mismatches that manual review misses.

The table below lists the CPT codes that most often appear with S62.036B, plus one frequent mismatch.

Payer coverage and prior authorization considerations

Medicare does not routinely require prior authorization for scaphoid fracture surgery, but individual Medicare Advantage plans and commercial payers vary significantly. Always verify prior authorization requirements with the specific plan before scheduling elective ORIF. Emergent open fracture repair generally proceeds without authorization, but the claim must still meet medical necessity criteria on review. Check the MAC’s Local Coverage Determinations (LCDs) and each commercial payer’s policy for scaphoid fracture surgery. Remittance advice from past claims also shows which payers have denied this code before.

• Medicare: Claims submitted with S62.036B are subject to standard Medicare Part B medical necessity review. The open fracture designation (seventh character B) supports surgical intervention. The documentation must still show why surgery was clinically indicated over conservative management.
• Commercial payers: Most major commercial payers follow AMA CPT and ICD-10-CM coding guidelines. Prior authorization and documentation rules still vary by plan.
• Workers’ compensation: State workers’ compensation rules vary. Some states require a separate authorization for scaphoid ORIF even for open fractures. Do not apply blanket rules across states — check with the specific carrier and state guidelines before submitting.
• Bundled payments: Under a bundled payment arrangement for musculoskeletal care, open fracture coding affects which bundle applies. It also decides which additional codes are included. Review the bundle definition before assuming S62.036B falls inside or outside it.

Common claim denials for S62.036B and how to avoid them

Claim denials for S62.036B cluster around five root causes. Each one is preventable with a documentation checklist applied before the claim leaves the practice. Routing open-fracture claims through a pre-submission review cuts rework. A denied open-fracture claim typically needs the operative report resubmitted, not just a corrected claim form. A clean claim on the first pass depends on verifying all six documentation elements before charge entry.

Scaphoid fracture nonunion and sequela codes

Proximal scaphoid fractures have higher nonunion rates than distal-pole fractures, a pattern attributed to the retrograde blood supply of the proximal pole. Even so, coders should rely on physician confirmation of nonunion, not anatomical inference, when selecting subsequent-encounter codes. When a fracture originally coded as S62.036B develops nonunion, switch to S62.036K (subsequent encounter for fracture with nonunion). Do not keep using S62.036B. The switch requires a note from the treating physician that explicitly diagnoses nonunion.

How Pabau keeps open scaphoid fracture claims clean

Open-fracture claims often stall on details that were in the chart all along. A coder picks the unspecified-wrist code, or re-keys insurer details by hand, and the problem only shows up when the rejection arrives.

Pabau pulls the patient, treatment, and insurer details from the patient record into a pre-filled submission. Its medical claims management tools run validation checks each time you send a claim. US practices then submit through Claim.MD without leaving Pabau.

Each claim sits in one dashboard as pending, submitted, processing, paid, or error. So an S62.036B claim that comes back for laterality or missing open-fracture documentation is visible right away, not weeks later.

Stop chasing fracture claim denials

Pabau pre-fills each claim from the patient record and runs validation checks before it goes out. Track every open-fracture claim from submission to payment in one view.

Conclusion

S62.036B is rarely the final code for an open scaphoid fracture that reaches surgery. The side is almost always somewhere in the chart, and finding it moves the claim to S62.034B or S62.035B.

The other trap is importing Gustilo logic from radius and tibia codes. On a wrist fracture, the wound grade shapes the surgical plan but leaves the seventh character alone. Any open S62 fracture at the initial encounter takes B.

Build those two checks into charge entry, and the code on the claim will match the operative report. To see how Pabau supports orthopedic and urgent care billing, book a demo.
