CPT code 29806 – Shoulder arthroscopy with capsulorrhaphy

Key takeaways

CPT code 29806 covers arthroscopic shoulder capsulorrhaphy, including Bankart and anterior-to-posterior labral repair. SLAP repair belongs to 29807.

When 29806 and 29807 are both performed on the same date of service, 29806 is billed as the primary procedure.

CPT 29826 (acromioplasty) is subject to CCI bundling edits with 29806. Append modifier 59 or XS when a distinct acromioplasty is separately documented.

At the 2026 conversion factors, the national facility payment for 29806 is $972.97, or $977.82 for a qualifying APM participant.

Practice management software like Pabau validates 29806 claims against built-in CPT and ICD-10 catalogues before they reach the payer.

CPT code 29806: Official descriptor and procedure scope

CPT code 29806 describes arthroscopy, shoulder, surgical; capsulorrhaphy.

The American Medical Association’s CPT code set places 29806 in the musculoskeletal arthroscopy section, alongside the other shoulder surgical codes. Capsulorrhaphy here means tightening or repairing the joint capsule. Surgeons most often do it to correct instability after a Bankart lesion, an anterior dislocation, or multidirectional shoulder instability.

The procedure bundles several surgical elements under one code. Coders do not report suture anchor placement, labral repair, or capsular plication separately when each forms part of the same capsulorrhaphy.

CPT 29806 vs 29807: How to choose the right code

The split between 29806 and 29807 is the most frequently audited coding decision in shoulder arthroscopy. CPT 29806 covers capsulorrhaphy and Bankart-type labral repair. CPT 29807 covers repair of the superior labrum anterior to posterior, the SLAP tear. Anatomical location and repair type decide the code, whatever terminology the surgeon prefers.

Where a surgeon performs both a capsulorrhaphy and a SLAP repair in one session, 29806 is the primary procedure. 29807 is secondary, with modifier 51. Document both repairs in the operative note with clear anatomical landmarks.

Codes commonly billed alongside 29806

Several shoulder arthroscopy codes turn up on the same claim as 29806. Whether each one is separately billable depends on CCI edits and payer policy, and bundling mistakes here are a leading source of orthopedic claim rejections.

CMS updates CCI edits quarterly. Check the current NCCI table for 29806 and 29826 before submitting, because bundle status can shift between fiscal years.

Modifiers that 29806 claims require

Modifier selection is a top denial driver on these claims. The wrong modifier, or a missing required one, either bounces the claim or pays it at the wrong rate.

• RT / LT (right/left laterality): Required by most payers. Always append the correct laterality modifier to 29806. Missing laterality triggers an automatic edit on many payer systems.
• Modifier 51 (multiple procedures): Append it to the secondary shoulder arthroscopy procedure when two are performed in one session. Where 29806 is primary, modifier 51 goes on 29807, 29827, or another secondary code.
• Modifier 50 (bilateral): Use it only when the identical procedure is performed on both shoulders in the same session. Bilateral shoulder capsulorrhaphy is rare, so document it clearly.
• Modifier 59 / XS (distinct procedural service): Required to unbundle 29826 from 29806 when a separate acromioplasty is performed and documented. Never use 59 routinely, because it needs operative note evidence of a separate service.
• Modifier 22 (unusual procedural complexity): Cannot be appended routinely. The operative note must name the factors that substantially increased operative time, such as extreme obesity, adhesions from prior surgery, or an anatomical anomaly. Payers audit modifier 22 claims heavily.

ICD-10 codes that support medical necessity

The diagnosis code on a 29806 claim must match the surgical findings in the operative report. A pre-operative impression does not suffice, because the final diagnosis should reflect what the surgeon confirmed arthroscopically. The codes below come from the ICD-10-CM code set and are the ones payers most often accept for this procedure.

Prior authorization requirements by payer type

Most commercial payers and Medicare Advantage plans require prior authorization for shoulder arthroscopy, 29806 included. Traditional Medicare Parts A and B do not, though Medicare Advantage plans frequently do. Medicaid rules vary by state. Confirming eligibility and authorization before surgery is the first defense against a post-service denial.

Payers commonly apply these clinical criteria when approving a 29806 authorization:

• Documented failed conservative treatment, typically at least six weeks of physical therapy
• MRI or MR arthrogram confirming a labral tear or capsular pathology
• A specific ICD-10 diagnosis matching the planned procedure
• Physician documentation of functional limitation and instability episodes
• For some payers, a minimum number of documented dislocation events before an elective capsulorrhaphy is approved

Check the payer’s local coverage determination and prior authorization policy for the plan year every time. Approval criteria are not identical across plans.

2026 Medicare reimbursement and RVU breakdown

Medicare payment for 29806 comes from the 2026 Medicare Physician Fee Schedule. Two numbers drive it: the code’s total relative value units and the conversion factor. For 2026 there are two conversion factors rather than one, so the same code pays two different national amounts.

The split conversion factor is new for 2026, and it is worth seeing the arithmetic laid out before you quote a figure to a surgeon.

Both figures are national and unadjusted. Your locality rate will differ once Geographic Practice Cost Indices are applied, so confirm it with the CMS MPFS lookup tool. Commercial payers typically pay a multiplier above the Medicare allowable, which your payer contracts will set.

The 90-day global surgery period applies to 29806 under Medicare. Routine wound checks, suture removal, and standard follow-up inside that window fall within the global package. None of them are separately billable without a modifier, such as modifier 24 for an unrelated E/M service.

Why 29806 claims are denied, and how to prevent it

Denial patterns on this code are predictable. Four root causes account for most of them: the wrong code, a thin operative note, missing prior authorization, and bundling errors. Naming the root cause is the first step toward an appeal that works, which is where denial management strategies earn their keep.

The claim adjustment reason code on the remittance tells the billing team which appeal path to take. CARC 4 means the procedure code is inconsistent with the modifier used, or that a required modifier is missing. CARC 197 means precertification or authorization was absent. CARC 97 means the service is bundled into another payment, and CARC 50 means the payer did not consider it medically necessary.

Documentation checklist before you submit

A well-documented operative report is the foundation of a defensible 29806 claim. Payers running a retrospective audit pull the op note first, so every element below should be confirmed before the claim goes out.

• Confirmed arthroscopic approach: The op note must state that the procedure was performed arthroscopically, describing portal placement and visualization. An open approach shifts coding to CPT 23455.
• Specific structures repaired: Name each structure repaired, whether anterior labrum, posterior labrum, or capsule. Vague language such as “instability repair” is insufficient.
• Suture anchor details: Document the number and type of anchors used. Payers do not reimburse anchors separately under 29806, but the detail supports medical necessity.
• Laterality stated explicitly: Left or right shoulder must appear in the op note header and in the coding. It has to match the RT or LT modifier on the claim.
• Surgeon attestation: The operative report is signed and dated by the performing surgeon before submission.
• Pre-op and post-op diagnosis codes match: The final ICD-10 code on the claim should reflect the confirmed intraoperative findings, not only the pre-operative impression.
• Prior authorization number on file: For commercial and Medicare Advantage plans that require authorization, the number must appear on the CMS-1500 claim form.
• Conservative treatment documented: Chart notes confirming prior physical therapy, injections, or other failed management, which medical necessity review will ask for.

How Pabau keeps 29806 claims clean before submission

In most orthopedic billing teams these checks happen by hand. Someone reads the operative note, matches the ICD-10 code, confirms the laterality modifier, then looks up the authorization number in a payer portal. Every one of those steps is a place where a 29806 claim goes out wrong.

Pabau, practice management software for busy practices, moves those checks into the claim itself. Built-in CPT and ICD-10 catalogues validate the pairing as the claim is built. Submission then runs through the Claim.MD clearinghouse, so real-time payer edits are applied before adjudication rather than after a denial.

Remittance advice comes back electronically against the original claim, so the team can see which 29806 claims paid short and why. That is the job orthopedic claims software should be doing: less rework after the fact, and a shorter path from surgery to payment.

Take the billing errors out of orthopedic claims

Pabau validates CPT 29806 claims against built-in CPT and ICD-10 catalogues, then submits them through the Claim.MD clearinghouse. Orthopedic practices see fewer denials and less rework inside the 90-day global period.

Conclusion

What decides a 29806 claim happens before it is submitted, not after it is denied. Read the operative note for the anatomy, choose between 29806 and 29807 on that basis, then confirm laterality, authorization, and the 29826 modifier. Those four checks settle most of the risk on this code.

A denied 29806 costs the practice twice, because the 90-day global period means the follow-up care is already committed. Book a demo to see how Pabau validates shoulder arthroscopy claims before they reach the payer.
