CPT Coding for Arthroscopic Rotator Cuff Repair with Biceps Tenodesis
For arthroscopic rotator cuff repair with biceps tenodesis, use CPT code 29827 (arthroscopic rotator cuff repair) in combination with either CPT 29828 (arthroscopic biceps tenodesis) or CPT 23430 (open biceps tenodesis), depending on the surgical approach used for the tenodesis.
Primary Coding Structure
The billing requires two separate CPT codes because these represent distinct surgical procedures performed during the same operative session:
- CPT 29827: Arthroscopy, shoulder, surgical; with rotator cuff repair
- Plus one of the following:
- CPT 29828: Arthroscopy, shoulder, surgical; biceps tenodesis (for arthroscopic approach)
- CPT 23430: Tenodesis of long tendon of biceps (for open approach)
Key Coding Considerations
Approach Selection Matters for Reimbursement
Arthroscopic biceps tenodesis (CPT 29828) consistently reimburses at higher rates than open biceps tenodesis (CPT 23430) 1, 2. In a large database analysis, open tenodesis was associated with $5,542 lower costs than arthroscopic tenodesis when performed with rotator cuff repair 1. However, Medicare reimbursement data from 2005-2024 shows arthroscopic tenodesis maintains higher reimbursement per service throughout this period 2.
Documentation Requirements
Your operative note must clearly document:
- The rotator cuff tear characteristics (size, tendons involved)
- The specific repair technique used for the rotator cuff
- The indication for biceps tenodesis (pathology of long head biceps)
- Whether tenodesis was performed arthroscopically or through open approach
- The specific fixation method for the tenodesis
Common Billing Pitfalls to Avoid
Do not use both CPT 29828 and 23430 together - cases that included both codes were excluded from major database analyses as they represent coding errors 1. Choose the code that accurately reflects your surgical approach.
Modifier usage: Depending on payer requirements, you may need modifier -51 (multiple procedures) on the secondary code, though many payers have automated this adjustment.
Additional Procedures
If you performed other concomitant procedures, add appropriate codes:
- CPT 29824: Subacromial decompression (adds approximately $10,669 to costs) 1
- CPT 29824: Distal clavicle excision (adds approximately $3,210 to costs) 1
These are separately billable when performed with rotator cuff repair and biceps tenodesis.
Clinical Context from Evidence
The evidence shows that 78.3% of rotator cuff repairs with biceps tenodesis use the arthroscopic approach (CPT 29828) versus 21.7% using open approach (CPT 23430) 1. This trend aligns with broader Medicare data showing significant increases in arthroscopic biceps tenodesis utilization from 2005-2024 2.
Important caveat: While both techniques are clinically effective with similar long-term outcomes, reoperation rates at 1 year are actually higher in patients who undergo concomitant biceps tenodesis compared to isolated rotator cuff repair 3. This doesn't affect coding but is relevant for informed consent and patient counseling.
