If you're working in medical billing or orthopedic surgery, you've probably scratched your head over CPT codes 29806 and 29807. They look similar, sound similar, and both deal with shoulder arthroscopy. But trust me, using the wrong one can lead to claim denials and payment headaches.
Let me break down everything you need to know about 29806 vs 29807 so you can code with confidence.
What Are CPT Codes 29806 and 29807?
Both of these codes fall under arthroscopic shoulder procedures. The American Medical Association (AMA) created these specific codes to describe different types of surgical work done inside the shoulder joint using an arthroscope—that tiny camera surgeons use to see what's happening without making big incisions.
CPT 29806 covers arthroscopy of the shoulder with capsulorrhaphy. This means the surgeon is tightening or repairing the joint capsule, which is the fibrous tissue surrounding your shoulder joint.
CPT 29807 describes arthroscopy with debridement. Here, the surgeon removes damaged tissue, bone spurs, or other problematic material from inside the shoulder joint.
The key difference? One fixes and tightens things (29806), while the other cleans things out (29807).

Understanding CPT Code 29806 in Detail
When a patient has a loose or unstable shoulder—maybe from sports injuries or repeated dislocations—surgeons often perform capsulorrhaphy. This procedure involves tightening the capsule around the shoulder joint to prevent it from moving too much.
The surgeon makes small incisions and uses specialized instruments to either shrink the capsule tissue or use sutures to pull it tighter. Sometimes they reattach the capsule to the bone if it has pulled away.
Common Scenarios for 29806
- Athletes with recurrent shoulder dislocations
- Patients with multidirectional instability
- Post-traumatic shoulder looseness
- Failed previous stabilization attempts
The procedure typically requires more surgical skill and time compared to simple debridement. That's why the reimbursement is usually higher.
Breaking Down CPT Code 29807
Debridement sounds fancy, but it's basically cleaning house inside your shoulder. The surgeon removes torn cartilage, inflamed tissue, loose fragments, or bone spurs that are causing pain and limiting movement.
This code gets used frequently because many shoulder problems involve some degree of tissue damage that needs removal. The surgeon visually inspects the joint through the arthroscope and trims away anything that shouldn't be there.
When 29807 Gets Used
- Partial rotator cuff tears
- Shoulder impingement syndrome
- Loose bodies in the joint
- Inflamed or damaged labrum
- Arthritic changes with debris
The procedure is generally quicker than capsulorrhaphy, and patients often recover faster too.
Key Differences Between 29806 vs 29807
Let's get into the nitty-gritty of what separates these two codes.
Surgical Technique
With 29806, the surgeon is actively repairing and reconstructing. They're using sutures, anchors, or thermal devices to modify the capsule structure. It's reconstructive work.
With 29807, the focus is removal. The surgeon uses shavers, biters, and graspers to take out problematic tissue. It's more about subtraction than addition.
Patient Presentation
Patients needing 29806 usually complain about their shoulder "popping out" or feeling unstable. They might describe a sensation that their shoulder could dislocate at any moment.
Patients requiring 29807 typically report pain with specific movements, grinding sensations, or catching feelings inside the joint. The shoulder feels mechanically blocked rather than loose.
Documentation Requirements
For 29806, your operative notes need to clearly describe:
- The capsular pathology identified
- The technique used for repair (thermal, suture, etc.)
- Which part of the capsule was addressed
- Any anchors or sutures placed
For 29807, documentation should include:
- What tissue was debrided
- The extent of damage found
- How much material was removed
- The condition of surrounding structures
According to medical coding experts at big write hook, proper documentation makes all the difference in getting these claims approved on the first submission.
Which Procedure Costs More?
Insurance reimbursement varies by region and payer, but generally CPT 29806 pays better than 29807. Why? Because capsulorrhaphy is more complex, takes longer, and requires more surgical expertise.
Medicare's national average for 29806 runs around $1,200-$1,500, while 29807 typically reimburses between $600-$1,200. Private insurers may pay differently, and geographic adjustments apply.
Factors Affecting Payment
- Geographic location (urban vs rural)
- Facility vs office setting
- Insurance plan type
- Patient's deductible status
- Whether other codes are billed simultaneously
Some surgeons use both codes together if they perform capsulorrhaphy and debridement during the same procedure. However, you need to check for bundling edits and modifier requirements.
Recovery and Outcomes
Patient recovery differs significantly between these procedures.
Recovery for 29806
- Immobilization for 4-6 weeks
- Physical therapy for 3-6 months
- Return to sports around 6-9 months
- Success rate approximately 85-90%
The rehab process is slower because the repaired capsule needs time to heal properly. Patients can't rush it or risk re-injury.
Recovery for 29807
- Sling use for 1-2 weeks
- Physical therapy for 6-12 weeks
- Return to normal activities in 3-4 months
- Symptom improvement in 70-85% of cases
Debridement recovery moves faster since there's no repair that needs to heal. Patients start moving their shoulder sooner.
Common Coding Mistakes to Avoid
I've seen plenty of billing errors with these codes over the years. Here are the biggest mistakes:
Using 29807 When 29806 Is Appropriate
If the surgeon performed capsulorrhaphy, you can't downcode to debridement just because it seems simpler. That's inaccurate coding and could be considered fraud.
Not Checking NCCI Edits
The National Correct Coding Initiative has specific bundling rules for shoulder arthroscopy codes. Always run your code combinations through an NCCI checker before submitting.
Missing Modifier Requirements
Sometimes you'll need modifier 59 or XS to indicate distinct procedural services. Don't forget these when appropriate.
Inadequate Documentation
Vague operative notes lead to denials. Make sure your surgeon documents exactly what they did and why.
Real-World Clinical Scenarios
Let me give you some practical examples of when to use each code.
Scenario 1: A 22-year-old volleyball player has dislocated her shoulder three times in the past year. MRI shows capsular laxity. Surgeon performs arthroscopic capsulorrhaphy with suture anchors.
Correct Code: 29806
Scenario 2: A 45-year-old construction worker has shoulder pain with overhead work. Arthroscopy reveals a frayed labrum and bone spur. Surgeon debrids the torn labrum and removes the spur.
Correct Code: 29807
Scenario 3: A 30-year-old swimmer has instability and also has damaged tissue. Surgeon tightens the capsule and removes some loose cartilage fragments.
Correct Codes: Both 29806 and 29807 (with appropriate modifier)
Which Code Is Better for Your Practice?
There's no "better" code—it depends entirely on what the patient needs and what the surgeon performs. However, from a practice management standpoint, 29806 generates higher revenue per case.
That said, 29807 procedures are often quicker, meaning you can potentially schedule more cases in a day. The volume vs complexity trade-off is somthing each practice needs to evaluate.
Practice Considerations
- Surgeon expertise and training
- Patient population demographics
- Insurance payer mix
- Facility capabilities
- Staff experience with post-op protocols
Insurance Coverage and Pre-Authorization
Most insurance companies cover both procedures, but pre-authorization requirements differ. Generally, 29806 needs more thorough documentation for approval because it's considered more invasive.
You'll typically need to submit:
- Imaging reports (MRI, X-ray)
- Conservative treatment history
- Clinical examination findings
- Functional limitation documentation
Some insurers require proof that the patient tried physical therapy first, especially for debridement procedures.
Final Verdict: 29806 vs 29807
So which code should you use? The answer is simple: use the code that accurately describes what the surgeon did.
Choose 29806 when the primary goal is stabilizing a loose shoulder through capsular repair or tightening. This is your go-to for instability cases.
Choose 29807 when the main objective is removing damaged tissue, bone spurs, or debris from the joint. This fits most impingement and degenerative cases.
Never choose a code based on payment rates or ease of approval. Choose based on clinical accuracy. That's not just good ethics—it's the law.

Frequently Asked Questions
Can you bill 29806 and 29807 together?
Yes, you can bill both codes if the surgeon performs both capsulorrhaphy and debridement during the same procedure. However, you'll likely need a modifier (usually 59 or XS) to indicate they were distinct services. Always check current NCCI edits.
How long does pre-authorization take for these procedures?
Most insurance companies respond within 3-5 business days for routine cases. Complex or revision surgeries might take 7-10 days. Submit authorization requests early to avoid scheduling delays.
What if the surgeon only did limited debridement during capsulorrhaphy?
If debridement was minimal and incidental to the primary capsulorrhaphy procedure, you should only code 29806. The debridement needs to be substantial and separately identifiable to justify billing both codes.
Do these codes include rotator cuff repair?
No, these codes don't include rotator cuff repair. If the surgeon also repairs the rotator cuff, you'll need to use additional codes from the 29827 series.
What's the appeal process if insurance denies the claim?
Start by reviewing the denial reason carefully. Most denials happen due to documentation issues or authorization problems. Submit a written appeal with supporting clinical notes, imaging reports, and a letter of medical necessity from the surgeon within the timeframe specified in your denial letter.
Conclusion
Understanding the difference between 29806 vs 29807 doesn't have to be complicated. One stabilizes, one cleans. One takes longer, one recovers faster. Both serve important roles in shoulder arthroscopy.
The most important thing? Code accurately based on what actually happened in the operating room. Review your surgeon's operative notes carefully, check for proper documentation, and verify payer-specific rules before submitting claims.
When you get these codes right, you'll see fewer denials, faster payments, and happier surgeons. And that's what good medical coding is all about.
