CPT Code 29916: Hip arthroscopy labral repair billing guide

CPT Code 29916 is the billing code for arthroscopy, hip, surgical; with labral repair. The surgeon uses an arthroscope to reach the hip joint and reattach a torn or detached labrum.

According to the American Medical Association, which maintains the CPT code set, 29916 includes any diagnostic arthroscopy performed in the same operative session. That means you cannot bill a separate diagnostic arthroscopy code alongside it. Medicare pays about $930.55 for the code nationally in 2026.

This reference covers the 2026 Medicare fee schedule, modifier rules, the ICD-10 crosswalk, NCCI bundling edits, ASC considerations, and documentation requirements. It also explains when 29999 replaces 29916, so billing teams and orthopedic practice managers can submit clean claims for hip labral repair.

Key takeaways

CPT Code 29916 describes arthroscopy, hip, surgical with labral repair. Diagnostic arthroscopy is included in it and cannot be billed separately.

The 2026 Medicare national rate is about $930.55, built on 14.63 work RVUs and 27.86 total RVUs. Rates still vary by GPCI locality.

Modifiers -LT and -RT for laterality and -22 for increased complexity are the ones you apply most often. A missing laterality modifier is the leading denial cause.

Pabau’s claims management software links the operative note to claim submission, so the documentation that justifies 29916 travels with the claim.

CPT Code 29916: Official description and clinical context

CPT Code 29916 is defined by the AMA as: Arthroscopy, hip, surgical; with labral repair. It sits in the Musculoskeletal System chapter of the CPT code set, under the Endoscopy and Arthroscopy subsection.

The code applies when the surgeon arthroscopically visualizes the hip joint and identifies a labral tear or detachment. The repair itself typically uses suture anchors to reattach the labrum to the acetabular rim.

Hip labral tears most commonly result from femoroacetabular impingement (FAI), hip dysplasia, or acute trauma. Payers approve the surgery only after conservative management has failed, so the record needs that history. Physical therapy, activity modification, and NSAIDs all count toward it.

The operative note should describe the tear morphology, the repair technique, and the number of suture anchors placed. It should also say why the surgeon repaired the labrum rather than debriding it.

Medicare fee schedule for CPT Code 29916

Medicare reimburses CPT Code 29916 under the Medicare Physician Fee Schedule (MPFS). The published rate is a national average, and your payment moves with the Geographic Practice Cost Index (GPCI) for your locality.

The figures below come from the CMS Physician Fee Schedule lookup tool. Verify them against current CMS data before billing.

Important note on rate accuracy: Medicare rates for CPT Code 29916 change every year. The figures above are the 2026 national averages published by FastRVU’s 2026 RVU lookup.

CMS lists the same amount for the facility and non-facility settings, because the procedure is effectively never performed in an office. Your own payment will differ once GPCI adjustments apply, so pull the official CMS MPFS file for final billing reference.

Facility vs non-facility and ASC considerations

Hip arthroscopy is almost never performed in a non-facility (office) setting. The procedure needs general or regional anesthesia and sterile arthroscopic equipment. Nearly all 29916 claims are therefore submitted from a hospital outpatient department or an ASC.

CMS confirms that CPT 29916 is payable in the ASC setting. The practice bills the professional component while the ASC bills its facility fee separately. Commercial payer contracts may override Medicare rates, so check your ASC participation agreements before billing.

Modifiers for CPT Code 29916

Modifier selection is one of the most denial-prone steps in billing hip arthroscopy. A missing laterality modifier is the single most common reason CPT 29916 claims are rejected on first submission. Use the table below to pick the right modifier for each clinical scenario.

Commercial payers often follow Medicare modifier policy, but verify payer-specific rules before submitting. Modifier -22 needs a separate written narrative explaining why the work was substantially greater than typical. Without it, the modifier will be ignored or denied.

ICD-10 diagnosis codes that support medical necessity

Every claim for CPT Code 29916 must carry an ICD-10-CM diagnosis code that establishes medical necessity. The codes below are the ones most commonly paired with hip labral repair, and the full ICD-10-CM code index covers the rest. Acceptance of any single code is payer-specific and subject to local coverage determinations.

Coders should select the most specific ICD-10-CM code that the operative findings and pre-operative imaging support. Document the imaging study, since MRI with arthrogram is typical for labral tears.

Record the failure of conservative treatment too, because payers that require prior authorization read it before approving surgery. The AAPC Codify CPT lookup carries current crosswalk data if you want to verify a pairing.

Related hip arthroscopy CPT codes: 29914, 29915, 29917

CPT Code 29916 is one of four surgical hip arthroscopy codes. Choosing the wrong sibling code is a common upcoding or undercoding error. The table below maps each code to its clinical meaning, so coders can pick the right descriptor from the operative report.

When the surgeon performs both a labral repair and a femoroplasty in the same session, 29914 and 29916 may both be billed with modifier -51. Check the NCCI edit pair for those codes before submitting, since payer policy varies. Billing 29916 when only debridement was performed is upcoding, and it triggers audit risk.

The distinction usually comes down to a few words in the operative report. The map below shows which phrase supports which code.

NCCI edits and bundling rules for CPT Code 29916

The National Correct Coding Initiative (NCCI) defines which code pairs cannot be billed together without a modifier. For CPT Code 29916, the most important bundling rules are:

• Diagnostic arthroscopy (CPT 29860 or 29861) is bundled. It cannot be billed on the same day as 29916. The surgical arthroscopy inherently includes the diagnostic component.
• CPT 29917 (labral debridement) is bundled with 29916. You cannot bill both repair and debridement on the same hip in the same session.
• 29914 and 29915 may be separately billable with modifier -51 when performed in addition to the labral repair. Check the NCCI PTP edit tables for their current status before submitting.
• Modifier -59 (or XS/XU/XE/XP) is required to unbundle any code pair whose NCCI edit carries a modifier indicator of 1. That indicator means the edit can be overridden with documentation of a distinct service.

Before submitting any 29916 claim with additional codes, verify the current NCCI PTP edit tables via the CMS code list. The tables are updated quarterly, so an edit that was bypassable last year may have changed. When one of those conflicts does reach the payer, managing claim denials becomes the billing team’s next job.

Documentation requirements and common billing errors

Insurers deny CPT Code 29916 claims more often over thin documentation than over coding errors. The operative note is the foundation of every hip labral repair claim.

A note reading only “hip arthroscopy with labral repair” is not enough for most commercial payers. Without the technique, the anchor count, and the tear extent, expect a medical records request or an outright denial.

Structured operative note templates that prompt the surgeon for each required element bring denial rates down. The prompt catches a missing laterality line or an unrecorded anchor count while the surgeon is still writing. That is weeks earlier than a payer audit would find it.

When to use CPT 29999 instead of CPT Code 29916

CPT 29999 is the unlisted arthroscopy procedure code. Use it when the procedure performed matches no specific descriptor in the 29914-29917 range. It is not a workaround for a poorly documented procedure that actually fits 29916.

• Use 29916 when the surgeon repaired a torn or detached labrum using suture anchors, bioabsorbable anchors, or a comparable fixation technique. The labrum was reattached to or reinforced against the acetabular rim.
• Use 29999 when the procedure involved a labral reconstruction using graft tissue, autograft or allograft, rather than a primary repair. No code in the 29914-29917 family describes graft-based reconstruction.
• Use 29999 when a new or experimental technique was performed that the AMA CPT Editorial Panel has not yet assigned a code. Certain capsular reconstruction procedures and novel anchoring systems fall here, where the repair method differs materially from standard technique.

Submitting 29999 requires a cover letter or an attached operative report. It has to explain the procedure in detail and say why no existing code applies. It also needs a crosswalk to the closest analogous code, usually 29916, so the payer can price the service.

Without that package, 29999 claims are typically denied on first submission. Practices that handle unlisted codes often keep a standard 29999 submission template, so the documentation is consistent every time.

How Pabau supports hip arthroscopy billing workflows

A denied CPT Code 29916 claim costs more in aged revenue than in rework time. Repeated appeal cycles push the payment further out every round. Orthopedic practices that keep clinical documentation and billing in separate systems lose the most here.

The handoff between the two systems is where denial-causing errors enter. The coder never sees the full operative note, the laterality modifier is dropped at submission, or the medical necessity narrative never attaches to the claim.

Practice management software like Pabau keeps the clinical record and the billing queue in one system. Our orthopedic claims management tools carry the operative note, the diagnosis codes, and the procedure codes together. When a hip labral repair claim is built, the clinical note is already attached to it.

Billing staff can verify laterality, confirm the repair technique matches 29916 rather than 29917, and attach the imaging report before the claim leaves the practice. Pabau’s Claim.MD integration then handles the electronic route out. It covers claim submission, payer eligibility checks, claim status tracking, remittance advice, and payer enrollment.

For orthopedic and sports medicine practices running high volumes of arthroscopic procedures, that single workflow keeps scheduling, clinical documentation, and billing in step. Electronic claim submission from the same record removes the manual re-entry that causes avoidable rejections.

Reduce hip arthroscopy claim denials

Pabau connects clinical documentation to claim submission in one workflow. Operative notes captured at the point of care link directly to your billing queue. The documentation that justifies CPT Code 29916 is attached when the claim goes out.

Conclusion

The operative report decides whether a hip labral repair claim gets paid. If it names the anchors, the tear extent, and the side, the code and the modifiers follow from it without argument. If it does not, no amount of billing skill will rescue the claim on appeal.

So the work that pays off is upstream. Give surgeons a note template that prompts for each required element, and the denials you are currently appealing mostly stop arriving. Book a demo to see how Pabau keeps hip arthroscopy documentation attached to the claim it justifies.
