CPT code 29882: Meniscus repair billing and reimbursement guide

Key Takeaways

CPT code 29882 describes arthroscopic knee surgery with meniscus repair (medial or lateral) – it is not used for meniscus removal (meniscectomy).

The 2026 Medicare national average reimbursement for CPT 29882 is approximately $761 in a facility setting and $1,117 in a non-facility setting – rates vary by locality.

Laterality modifiers LT (left) and RT (right) are required; billing 29882 and 29881 together for the same compartment violates NCCI bundling rules.

Pabau’s claims management software links orthopedic procedure documentation to CPT code selection, reducing manual coding errors at the point of care.

Official descriptor for CPT code 29882 is: Arthroscopy, knee, surgical; with meniscus repair (medial OR lateral).

CPT code 29882 covers an arthroscopic approach in which the surgeon repairs a torn meniscus rather than removing it. The repair may involve the medial meniscus, the lateral meniscus, or both (though both-compartment repair is coded separately under CPT 29883). The code falls within the Musculoskeletal Endoscopy/Arthroscopy section of the AMA’s CPT code set.

The “medial OR lateral” language in the descriptor is significant. CPT 29882 applies when the surgeon repairs one compartment. When both the medial and lateral menisci are repaired in the same session, CPT 29883 is the correct code. Using 29882 twice (or 29882 + 29883) for a bilateral-compartment repair is a common upcoding error that NCCI edits are designed to catch.

2026 Medicare reimbursement and fee schedule for CPT 29882

Medicare reimbursement for CPT code 29882 is calculated from the CMS Physician Fee Schedule and varies by geographic locality, facility type, and the annual conversion factor. The figures below reflect 2026 national averages; your local Medicare Administrative Contractor (MAC) locality multiplier will adjust the actual payment. Tracking these rates against actual paid claims is one area where revenue cycle management tools add measurable value.

Use the FastRVU 2026 RVU lookup tool to verify current rates by locality before submitting claims. Commercial payers typically reimburse at a percentage of the Medicare fee schedule, though contracted rates vary. Connecting reimbursement intelligence to your practice’s actual claim performance, rather than relying on static reference data, is the difference between benchmarking and actionable billing oversight. Pabau’s claims management software surfaces this data within the practice management workflow, linking claim status to patient records without requiring a separate reference tool.

RVU breakdown for CPT 29882

RVU values are set annually under the CMS Medicare Physician Fee Schedule final rule. The work RVU reflects clinical labor and complexity; the large gap in practice expense RVU between facility and non-facility settings reflects the overhead assumed by the hospital or ASC versus the physician’s own office. Always verify against the current year’s CMS data before making reimbursement projections.

Applicable modifiers for CPT code 29882

Modifier selection is one of the highest-risk areas in arthroscopic billing. An incorrect or missing modifier is among the most common reasons CPT code 29882 claims are denied or downcoded. The AAPC Codify platform provides searchable modifier guidance alongside the code descriptor.

Laterality modifiers LT and RT are effectively mandatory for unilateral joint procedures. Omitting them on claims destined for Medicare or most commercial payers will typically result in a denial or a request for additional information. The modifier 59 carries particular compliance sensitivity: using it to unbundle codes that are legitimately bundled – without clear documentation of a distinct clinical encounter or anatomical site – may constitute a billing compliance error.

ICD-10 diagnosis codes commonly paired with CPT code 29882

Medical necessity for CPT code 29882 requires a supporting ICD-10-CM diagnosis code that documents the meniscal pathology. The M23 series (internal derangement of the knee) and S83 series (traumatic injuries) are the most frequently paired codes. Payers use diagnosis-to-procedure crosswalks to validate medical necessity; an ICD-10 code that does not align with a repair procedure (as opposed to a resection or diagnostic procedure) is a trigger for denial.

The 7th character in the S83 series matters: use “A” for the initial surgical encounter, “D” for subsequent encounter, and “S” for sequela. Using the wrong encounter suffix is a common documentation error that can affect claim adjudication. Verify specific ICD-10 codes against the current CMS code set, as codes in the M23 and S83 series are updated in the annual October release.

Documentation requirements for CPT code 29882

The operative note is the evidentiary foundation for CPT code 29882. Without it, payers have no basis to distinguish a repair from a resection, or to confirm the meniscus location involved. Orthopedic practices billing high volumes of arthroscopy code 29882 should ensure their operative note templates capture every required element, since many commercial payers and Medicare conduct targeted post-payment audits on surgical arthroscopy claims. Producing a complete operative note also underpins submitting a clean claim on the first pass, which directly reduces days in accounts receivable.

• Procedure confirmation: Explicit statement that a repair (not resection) was performed
• Meniscus location: Medial or lateral (or both, if 29883 applies)
• Repair technique: Suture technique (inside-out, outside-in, all-inside), anchor type, or other fixation method
• Tear pattern: Bucket-handle, radial, horizontal, complex, or degenerative – documents medical necessity
• Laterality of the knee: Right or left – must match the modifier on the claim
• Diagnostic findings: Arthroscopic findings observed before and after repair
• Surgeon attestation: Signed operative report with date of service matching the claim

Practices serving sports medicine patient populations, where meniscal injuries are high-volume, benefit from standardized operative note templates that pre-populate required elements. This reduces the documentation burden per case while improving audit defensibility. Pair this with generating a superbill directly from the clinical note to eliminate transcription errors between the surgical record and the billing submission.

NCCI edits and bundling rules for CPT code 29882

The National Correct Coding Initiative (NCCI) edits govern which codes can be billed together for the same date of service, patient, and operative session. CPT code 29882 has several significant bundling relationships that orthopedic billers must know. Failure to observe NCCI edits is a primary driver of denial management challenges in healthcare billing departments.

NCCI edit tables are updated quarterly. The information above reflects general principles; always verify against the current NCCI edit file from CMS before submitting claims. Using modifier 59 to bypass a bundling edit without clinical documentation to support a distinct service is a compliance risk – payers and CMS consider inappropriate use of modifier 59 a form of fraud in audits. Submitting claims through a clearinghouse that validates NCCI edits before transmission, such as electronic claims submission via Claim.MD, surfaces these bundling conflicts before they result in a payer rejection.

Related knee arthroscopy CPT codes: How CPT code 29882 compares

CPT code 29882 belongs to a family of knee arthroscopy surgical codes. Selecting the wrong code from this group is one of the most common errors in orthopedic billing, with repair-vs-resection confusion at the top of the list. The table below summarizes the key codes in this family and when each applies. For additional context on other CPT code families, see other CPT code reference guides on the Pabau procedure codes resource. Physical therapy practices that co-manage postoperative knee patients may also find Pabau’s physical therapy EMR software useful for linking rehab documentation to surgical billing records.

CPT 29882 vs CPT 29881: Repair vs meniscectomy

The 29882/29881 distinction is purely operative: did the surgeon preserve and repair the meniscal tissue, or remove it? An inside-out suture repair documents 29882. A partial meniscectomy removing the torn fragment documents 29881. The error arises when the operative note describes both a repair attempt and a partial resection. In that case, the dominant procedure governs – if the primary goal and documented outcome was repair, 29882 applies; if resection was the definitive treatment, 29881 applies. Billing 29882 when the operative note primarily documents resection is an upcoding risk.

Payer-specific policies and prior authorization for CPT 29882

Prior authorization requirements for CPT code 29882 vary significantly by payer and plan type. Medicare does not uniformly require prior authorization for knee arthroscopy, but Medicare Advantage plans frequently do – and their criteria can differ from traditional Medicare’s coverage rules.

Commercial payers typically impose medical necessity criteria that require documentation of failed conservative treatment (physical therapy, NSAIDs, rest) before approving arthroscopic meniscus repair. Failure to obtain authorization when required, or submitting a claim without meeting the payer’s documented medical necessity criteria, is a leading cause of post-adjudication denials for surgical arthroscopy.

Maintaining medical billing compliance for high-value surgical codes means tracking authorization status at the appointment level, not just at claim submission. Some orthopedic practices have reduced authorization-related denials by integrating prior auth tracking into their scheduling workflow – flagging CPT 29882 cases for auth review at the time the surgery is scheduled, not the day before the procedure.

Verifying insurance eligibility and benefits in advance also confirms whether the plan requires auth and what documentation the payer needs. The electronic remittance advice (ERA/835) returned after claim adjudication will include denial reason codes that specifically identify auth-related rejections, helping billing teams triage and appeal systematically.

Common coding errors with CPT code 29882

The most preventable billing losses on CPT code 29882 come from a handful of recurring mistakes. Each one has a specific documentation or workflow fix.

• Using 29882 when 29881 is correct: The operative note documents a partial meniscectomy, but the coder selects the repair code. This is upcoding – the operative note determines the code, not the intended procedure. Solution: require coders to review the specific technique section of the operative note, not just the pre-op diagnosis.
• Missing laterality modifier: Submitting 29882 without LT or RT. Solution: build a claim scrubbing rule that flags 29882 claims without a laterality modifier before transmission.
• Billing 29882 + 29883 together: These codes are mutually exclusive. Use 29882 for single-compartment repair and 29883 for bilateral-compartment repair – never both on the same claim for the same knee.
• Wrong ICD-10 specificity: Using an unspecified laterality ICD-10 code (e.g., M23.20 – unspecified knee) when the operative note documents right or left. Use the laterality-specific code to match the modifier and reduce medical necessity review risk.
• Unbundling without documentation: Appending modifier 59 to separately bill a bundled companion code (e.g., chondroplasty in the same compartment) without a distinct clinical rationale documented in the operative note. Always document the anatomical separation or clinical distinction before using modifier 59.

Conclusion

CPT code 29882 is straightforward in concept but carries real billing risk at the edges: repair vs. resection documentation, laterality modifier compliance, NCCI bundling rules, and payer-specific authorization requirements. Getting these right requires operative note templates that capture every required element and billing workflows that flag modifier and bundling issues before claims leave the practice.
