Key takeaways

CPT code 29807 is the AMA descriptor for arthroscopic shoulder surgery with repair of a SLAP lesion.

29807 applies to superior labral repairs, while CPT 29806 covers anterior-inferior Bankart repairs. Choosing the wrong one is the leading denial trigger.

A Type I SLAP lesion is usually debrided rather than repaired, so it maps to CPT 29823 instead of 29807.

CPT 29826 is a fixed add-on code, so it needs a listed primary procedure and takes no NCCI bypass modifier.

Pabau’s claims management software runs CPT validation and ICD-10 crosswalk checks at charge capture, before claims reach the payer.

CPT Code 29807 reports the arthroscopic repair of a SLAP lesion, a tear of the superior glenoid labrum. It is a Category I surgical code, and it sits in the Endoscopy/Arthroscopy subsection of the CPT code set.

The code covers superior labral repairs only. Anterior-inferior repairs, known as Bankart lesions, belong to CPT 29806, and mixing the two is the leading denial trigger on shoulder arthroscopy claims. Medical necessity comes from the S43.43 ICD-10 series, and payers expect a laterality modifier on every line.

CPT Code 29807: Official definition and code placement

The official AMA description for CPT Code 29807 is: Arthroscopy, shoulder, surgical; repair of SLAP lesion. The code set is maintained by the American Medical Association (AMA). It reports arthroscopic repair of the superior glenoid labrum, specifically tears classified as SLAP (Superior Labrum Anterior to Posterior) lesions.

Field Detail
CPT Code 29807
Official AMA Description Arthroscopy, shoulder, surgical; repair of SLAP lesion
Code Type Category I CPT (Surgical Procedure)
Section Surgery, Endoscopy/Arthroscopy
Anatomical Region Superior glenoid labrum (shoulder joint)
Surgical Approach Arthroscopic (minimally invasive)
Commonly Co-Billed With 29826 (add-on code), 29827, 29828

Clinical indications for arthroscopic SLAP repair

CPT Code 29807 is billable when a surgeon repairs a SLAP lesion arthroscopically, confirmed by clinical examination, MRI, or direct arthroscopic visualization. Overhead athletes account for most of the volume, so orthopedic and sports medicine practices report this code most often.

SLAP lesions fall into four types under the Snyder classification, and not every type is repaired. Medical necessity documentation has to name the type and record the failure of conservative management.

  • Type I: Fraying and degeneration of the superior labrum without detachment. Typically does not require repair; debridement (CPT 29823) may apply instead.
  • Type II: Detachment of the superior labrum and biceps anchor from the glenoid. Most common type requiring 29807.
  • Type III: Bucket-handle tear of the superior labrum with an intact biceps anchor. Repair or resection depending on tissue quality.
  • Type IV: Bucket-handle tear extending into the biceps tendon. May require 29807 combined with biceps tenodesis (CPT 29828).

The type drives the code, and two of the five findings a shoulder coder meets are not 29807 at all.

Only a repaired superior labral tear earns 29807, which is why the Snyder type belongs in the operative note. Mapping follows the Snyder classification and the AMA CPT descriptors.

The operative note must establish that the lesion involved the superior labrum, not the anterior-inferior labrum, which maps to CPT 29806. Documenting suture anchor placement, the number of anchors, and the repair technique strengthens the medical necessity record and reduces audit exposure.

CPT 29807 vs CPT 29806: Key differences

The 29807 versus 29806 distinction is where most SLAP repair denials originate. Both codes describe arthroscopic labral repair, but they cover anatomically distinct regions. Submitting the wrong one misstates the procedure performed as well as the charge.

Feature CPT 29807 (SLAP Repair) CPT 29806 (Bankart Repair)
Anatomical region Superior glenoid labrum Anterior-inferior glenoid labrum
Typical diagnosis SLAP tear (overhead athlete, traction injury) Bankart lesion (anterior shoulder instability, dislocation)
Primary ICD-10 S43.43 (Superior glenoid labrum lesion) S43.30 (Dislocation of shoulder joint), M24.31
Can be billed together? Yes, if both repairs are performed at separate anatomical sites with supporting operative documentation. Modifier 59 (or XS) is typically required on the second code.
Common coding error Using 29807 when the repair was anterior-inferior Using 29806 when the tear was purely superior

When a SLAP repair and a Bankart repair happen in the same session, both codes may be reported. The operative note has to document each repair as a distinct procedure at a separate anatomical location. Without that specificity, payers bundle one code and deny it.

ICD-10 codes used with CPT 29807

Every CPT 29807 claim needs a supporting ICD-10 diagnosis code that establishes medical necessity. The CDC/NCHS ICD-10-CM web tool is the authoritative source for confirming that a code is still valid for the current fiscal year.

ICD-10 Code Description Usage Context
S43.431A Superior glenoid labrum lesion of right shoulder, initial encounter Most common primary DX for 29807, right shoulder
S43.432A Superior glenoid labrum lesion of left shoulder, initial encounter Left shoulder SLAP repair, initial encounter
S43.439A Superior glenoid labrum lesion, unspecified shoulder Use only when laterality is not documented
M75.10 Rotator cuff syndrome, unspecified shoulder Secondary DX when concurrent rotator cuff pathology is documented
M75.11 Rotator cuff syndrome, right shoulder Secondary DX, right-sided concurrent pathology
M75.12 Rotator cuff syndrome, left shoulder Secondary DX, left-sided concurrent pathology

Always append the correct 7th character extension: “A” for initial encounter (surgical admission), “D” for subsequent encounter (follow-up), and “S” for sequela. Submitting S43.431 without the 7th character produces an invalid code and an automatic claim rejection.

Modifiers that belong on a 29807 claim

Modifier selection for CPT 29807 depends on the surgical setting, the laterality, and whether other procedures were performed in the same session. Payer policies vary, so verify modifier requirements with each payer before submission.

Modifier Description When to Use
RT / LT Right side / Left side Always append to indicate laterality; required by most payers
59 Distinct procedural service When 29807 and 29806 are both reported for repairs at separate anatomical sites, each supported by the operative note
XS Separate structure (subset of 59) Preferred over 59 by many payers when the two procedures involve different structures in the same joint
22 Increased procedural service When the procedure is significantly more complex than typical, such as an extensive revision SLAP repair. Requires detailed documentation.
51 Multiple procedures Appended to the secondary procedure when multiple shoulder arthroscopy codes are reported. Not used on add-on codes such as 29826.

Bilateral SLAP repair in a single session is rare clinically. When it does occur, append modifier 50 (bilateral procedure) or submit two line items with RT and LT. Payers differ on which they accept, so check the bilateral surgery rules before submitting.

Medicare reimbursement rates for 29807

Medicare reimbursement for CPT 29807 is set through the annual CMS Physician Fee Schedule lookup tool, which publishes facility and non-facility rates. Pull your locality-specific rate from that tool. National averages are useful for reference, but they should not be used for claim submission without GPCI verification.

Setting Rate Type Notes
Facility (ASC / Hospital) Lower physician payment (facility overhead absorbed by the facility) Verify the 2026 figure via the CMS MPFS Look-Up Tool; locality adjustments apply
Non-Facility (Office) Higher physician payment (practice overhead included) SLAP repair is rarely performed in an office setting, so this rate is mainly a pre-authorization benchmark
Geographic Adjustment (GPCI) Applied to Work, PE, and MP RVU components High-cost localities such as Manhattan and San Francisco pay more, and rural areas less. Use the CMS Look-Up Tool with your MAC locality code.

Practices that submit 29807 claims electronically route them through a clearinghouse, which reaches thousands of payers and carries its own CPT and ICD-10 catalogues.

That catalogue check is what stops a mistyped code before the claim reaches the Medicare Administrative Contractor (MAC). Take your 2026 RVU values from the CMS file itself rather than an aggregator, since third-party listings lag the annual update.

CPT 29807 belongs to a family of shoulder arthroscopy surgical codes. Reading the family together helps a coder pick the most accurate code, avoid unbundling errors, and report co-procedures correctly.

CPT Code Description Relationship to 29807
29806 Arthroscopy, shoulder, surgical; capsulorrhaphy (Bankart/anterior-inferior labral repair) Sibling code; same joint, different anatomical region. Cannot substitute for 29807.
29823 Arthroscopy, shoulder, surgical; debridement, extensive May be reported alongside 29807 with the appropriate modifier; covers Type I SLAP debridement
29824 Arthroscopy, shoulder, surgical; distal clavicle excision Co-procedure; reported separately with modifier 59 when AC joint pathology is also addressed
29826 Arthroscopy, shoulder, surgical; decompression of subacromial space (acromioplasty) Add-on code; reported with a listed primary such as 29807, and no bypass modifier applies
29827 Arthroscopy, shoulder, surgical; with rotator cuff repair Reported alongside 29807 when a rotator cuff tear is repaired in the same session
29828 Arthroscopy, shoulder, surgical; biceps tenodesis Common co-procedure with Type IV SLAP; reported separately with a modifier where applicable

One relationship in that table gets described incorrectly almost everywhere. CPT 29826 is a fixed add-on code under the CMS Type 1 designation.

It carries no procedure-to-procedure edit against its listed primaries, and 29807 is one of them. So there is no bundling to bypass and no modifier 59 or XS to append. What the payer needs on that line is the primary procedure on the same claim.

Pro Tip

Check the current quarter NCCI (National Correct Coding Initiative) edits before you report CPT 29807 with 29823 or 29806. Edit status changes each quarter, and a pair that paid in Q1 can bundle in Q2. Add-on codes such as 29826 are the exception, because they carry no procedure-to-procedure edit against their primaries. Pull the current NCCI table from cms.gov before you submit any multi-code shoulder claim.

Documentation requirements for a 29807 claim

Payers deny CPT 29807 claims for documentation deficiencies more often than for the wrong code. The operative note is the claim’s medical necessity record, so a pre-billing checklist should read it before the charge goes out.

The operative report for CPT 29807 must include all of the following elements to withstand payer review:

  1. Arthroscopic confirmation of SLAP tear: Describe the intraoperative visualization and characterize the tear by type, extent, and anterior-to-posterior involvement.
  2. Biceps anchor assessment: Document the stability and condition of the biceps long head anchor, which differentiates Type II/IV from Type I/III lesions.
  3. Repair technique: Name the fixation method, knotted or knotless, and describe how the labrum was mobilized and reattached.
  4. Anchor count and placement: State the number of suture anchors placed and their positions, such as the 11 o’clock and 1 o’clock positions.
  5. Conservative management failure: Reference pre-operative records confirming that physical therapy, activity modification, or another non-surgical treatment was attempted first.

Prior authorization is a separate requirement, and many commercial payers apply it to CPT 29807. An eligibility and authorization check belongs in the workflow before the procedure date. Practices that verify eligibility in real time catch a missing authorization while the surgery can still be rescheduled.

Common denial reasons, and how to prevent them

Orthopedic billing teams see a predictable set of denial patterns on 29807 claims, and each one is preventable with a workflow control. Our denial code reference explains the CARC codes that appear on the explanation of benefits, which is where these patterns surface first.

Denial Reason Root Cause Prevention
Wrong code selected 29806 submitted instead of 29807, or the operative note describes the anterior-inferior labrum while 29807 is billed Pre-billing review: the coder reads the operative note before assigning the code, and confirms that “superior” labrum language is present
Missing or incorrect modifier Laterality modifier (RT/LT) omitted, or modifier 59 missing when 29807 is billed with 29806 Charge entry checklist requires a laterality modifier on every shoulder code, with modifier logic built into the billing system rules
Add-on code billed without its primary 29826 reported alone, or with a bypass modifier that an add-on code does not take Report 29826 on the same claim as its primary procedure, and leave modifier 59 or XS off that line
Lack of medical necessity The ICD-10 code does not support SLAP repair, or the operative note lacks a conservative treatment history Use the S43.43x series as the primary DX, and ensure pre-operative notes document failed conservative treatment
Pre-authorization missing The commercial payer required authorization, and the surgery went ahead without it Real-time eligibility check at scheduling, with an authorization workflow triggered automatically for shoulder surgery cases
Invalid ICD-10 code Missing 7th character on the S43.43 series, or an unspecified code when laterality was documented Validate every diagnosis code before submission, using the validator in the clearinghouse or the practice management system

Pro Tip

Run a quarterly denial audit on your CPT 29807 claims using the ERA reports from your clearinghouse. Filter by CARC. CO-4 flags a procedure code inconsistent with the modifier used, or a required modifier that is missing. CO-97 flags payment already included in another adjudicated service. If one reason passes 15% of your 29807 volume, the fix is a workflow change rather than a run of appeals.

The same laterality and encounter-type requirements apply to every surgical claim. A control you build for shoulder codes usually pays off across the rest of the surgical schedule too.

How Pabau keeps 29807 claims clean before submission

A code reference answers one question, which is what to bill. It does nothing about the mistyped codes, missing modifiers, and unbundling errors that come back as denials weeks later. Those start at charge capture, so the control has to sit there too.

Practice management software like Pabau checks the CPT code, the modifier set, and the ICD-10 crosswalk while the charge is still being entered.

Pabau’s claims management software submits through the Claim.MD clearinghouse in the 837P format, and it reaches thousands of payers. Eligibility checks run in real time, and ERA (835) remittances match back against the charge automatically.

For shoulder surgery that order matters. Staff confirm that a plan covers arthroscopy before the procedure date, instead of finding the missing authorization on a denied claim. Denials then group by CPT code in reporting, so you can see whether 29807 is failing at one payer or across all of them.

Stop chasing 29807 denials after the fact

Pabau’s claims management integration validates CPT codes, modifiers, and ICD-10 crosswalks at charge capture, so shoulder arthroscopy claims reach payers clean the first time.

Conclusion

CPT Code 29807 bills cleanly when the operative note names the superior labrum, the biceps anchor, and the fixation used. Most denials trace back to a note that skipped one of those three. The rest come from a missing laterality modifier, or a code assigned before anyone read the report.

Two habits are worth building. Route every shoulder claim through a pre-billing check that reads the operative note against the code, and audit your 29807 denials once a quarter. Both cost less than the resubmission cycle they prevent.

Claims validation at charge capture makes both habits routine instead of a monthly scramble. Book a demo to see how Pabau handles surgical billing, from charge entry through to remittance matching.

Frequently asked questions

What is CPT Code 29807 used for?

CPT Code 29807 is used to report arthroscopic surgical repair of a SLAP (Superior Labrum Anterior to Posterior) lesion of the shoulder. It applies when a surgeon uses arthroscopic technique to reattach the detached or torn superior glenoid labrum, typically with suture anchors. This code does not apply to anterior-inferior (Bankart) labral repairs, which are reported with CPT 29806.

What is the difference between CPT 29806 and 29807?

CPT 29807 covers repair of the superior glenoid labrum (SLAP lesion), while CPT 29806 covers capsulorrhaphy and repair of the anterior-inferior labrum (Bankart lesion). The anatomical distinction is the billing distinction. A superior labral repair is 29807, and an anterior-inferior repair is 29806. Both can be reported in the same session with modifier 59 or XS when separate repairs are performed at each anatomical site.

What are the Medicare reimbursement rates for CPT 29807?

Medicare reimbursement for CPT 29807 varies by geographic locality and setting (facility vs. non-facility). The authoritative source for current figures is the CMS Physician Fee Schedule Look-Up Tool at cms.gov, which is updated annually. Published rates from third-party aggregators may lag behind the official PFS update, so verify any figure against the current CMS data file before you submit.

What modifiers apply to CPT code 29807?

The modifier most often required on a CPT 29807 claim is RT or LT for laterality. Modifier 59 or XS applies when 29807 and 29806 are both reported for separate repairs. Modifier 22 covers a procedure of significantly increased complexity, with supporting documentation. Modifier 51 applies to the secondary procedure when multiple arthroscopy codes are billed together. Payer requirements vary, so verify each payer’s modifier rules before submission.

Which ICD-10 codes are reported with CPT 29807?

The primary ICD-10 codes for CPT 29807 come from the S43.43 series. They are S43.431A for the right shoulder, S43.432A for the left, and S43.439A when laterality is unspecified, each for an initial encounter. Secondary diagnosis codes from the M75 series (rotator cuff syndrome) may be added when concurrent shoulder pathology is documented in the operative report.

Is CPT 29807 billable with CPT 29826 on the same day?

Yes. CPT 29826 is a fixed add-on code, so it is reported with a listed primary procedure, and 29807 is one of those primaries. There is no procedure-to-procedure NCCI edit between the two codes, so no modifier 59 or XS is needed to bypass a bundle. Report 29826 on the same claim as its primary procedure, and append no bypass modifier to that line.

What documentation is required for CPT 29807?

The operative report for CPT 29807 must document arthroscopic visualization of the SLAP tear and the biceps anchor assessment. It also needs the repair technique, the suture anchor type and number, and the anchor placement locations. Pre-operative evidence of failed conservative treatment completes the record. Missing any of these elements leaves the medical necessity record incomplete, which typically results in a payer denial or a post-payment audit recovery request.

What are common denial reasons for CPT code 29807?

The most frequent denial reasons for CPT 29807 are wrong code selection between 29807 and 29806, and a missing laterality modifier. Others include an add-on code such as 29826 reported without its primary procedure, and an invalid or incomplete ICD-10 code. Missing medical necessity documentation and missing pre-authorization round out the list. Most of these are preventable through pre-billing charge review and real-time eligibility verification.
