Monitor payer policy activity
Defines medical necessity, documentation, and coding guidance for open shoulder arthrotomy procedures (e.g., AC separation repair, acromioplasty, rotator cuff repair, distal clavicle resection, shoulder stabilization, synovectomy) for providers and payers.
Policy statements modified conservative management to require where noted for each indication both a medication trial and failure as well as a trial and failure of physical measures for decompression of subacromial space or acromioplasty for rotator cuff tendonitis, full thickness rotator cuff repair, resection of distal clavicle, shoulder dislocation, and synovectomy.
Policy statements modified to require additional testing for decompression of subacromial space or acromioplasty for rotator cuff tendonitis, full thickness rotator cuff repair, resection of distal clavicle, and shoulder dislocation.
Multiple CPT codes removed from the policy (including 20680, 20670, 23040, 23044, 23101, 23107, 23415, 23585, 23615, 23616, 23630; 23770 replaced with 23680).
Criteria for a number of specific indications (e.g., AC separation with recent traumatic event, partial thickness rotator cuff repair, removal of intra-articular osteochondral lesion or loose body, recurrent shoulder dislocation (greater than two years), initial shoulder dislocation with Bankart/Hill-Sachs/anterior glenoid rim fracture, shoulder fracture repair, and shoulder hardware removal) were deleted.

Derived from evidence summaries and guideline statements
Policy history modified statements to require dual conservative trials
All indications not listed in this policy, or any other situation where the specific policy criteria are not met, are considered not medically necessary and may be denied. Documentation submitted for review must support that the applicable indication-specific criteria are satisfied; absence of this documentation is grounds for denial.
Arthroscopic techniques are preferred for many shoulder conditions. Open procedures are reserved for select nonurgent cases when anatomy, failed prior arthroscopic surgery, or surgeon expertise favor an open approach. Use of open techniques should be limited to clinical scenarios where arthroscopy is insufficient to address the pathology and when the indication-specific criteria in this policy are met.
Criteria that were previously included in the policy but have been deleted (for example, criteria addressing acromioclavicular separation with recent traumatic event, partial-thickness rotator cuff repair, removal of intra‑articular osteochondral lesion or loose body, certain recurrent dislocation scenarios, shoulder fracture repair, and hardware removal) are no longer operative in this policy. Absence of indication‑specific criteria for those services may render them not covered unless addressed elsewhere in the member’s benefit plan.
Procedures or clinical situations not expressly listed in this policy, or that do not meet the stated indication-specific requirements, are considered not medically necessary. Providers should not rely on implicit coverage for unlisted indications and should submit supporting documentation if requesting review for exceptional circumstances.
The policy history documents that multiple indication-specific criteria were removed during prior revisions. When criteria for a given indication are deleted from the policy history, those services are no longer supported by this policy’s coverage criteria; claims for those services should be evaluated against current policy language and the member’s benefit contract, and may require prior authorization or be denied if not otherwise covered.

Provider Requirements, Authorization, and Documentation
Obtain prior authorization and support indication-specific necessity
Prior authorization is required per-indication when billed with the listed CPT codes; submit medical records that show the specific medical necessity criteria for the indicated procedure are met.
- Applies to CPT codes listed in the policy (see coding tables).
- Documentation must support the indication-specific criteria referenced in the policy.
Submit pre-authorization with conservative therapy and imaging
Pre-authorization is expected for listed open shoulder CPT codes when applicable; submit required documentation including conservative management and imaging/diagnosis supporting the surgical indication.
- Include documentation of failed conservative therapy and imaging (e.g., x-ray, MRI) per the indication.
- Use the policy's listed CPT codes when requesting pre-authorization.
Verify CPT list and obtain prior authorization
When the policy is in effect, prior authorization is required for the listed shoulder open procedure CPT codes; verify the final effective CPT list because some codes were removed in an interim review.
Document ~3 months of failed conservative management
Document that approximately three months of failed non-operative conservative management (medication trial such as NSAIDs or acetaminophen and, when appropriate, corticosteroid injection) has been attempted where required prior to surgery.
- Conservative management is not required for acute traumatic complete rotator cuff tears.
- Record medications tried (NSAIDs, acetaminophen, corticosteroid injections as appropriate) and durations.
Use a conservative-first, stepwise treatment approach
Follow a conservative-first, stepwise approach for nonurgent cases starting with physical therapy, pharmacologic management, and activity modification before progressing to surgery.
- PT and/or directed home exercise for at least 6 weeks is expected as part of conservative measures when specified.
- Escalate to surgical consideration only after documented failure of indicated nonoperative care.
Document both medication and physical therapy failures before authorization
Where specified, require and document both a medication trial (and failure) and a trial of physical measures (and failure) prior to authorization for listed open procedures.
- Policy revisions operationalize dual requirement (medication + physical measures) for decompression/acromioplasty, full-thickness rotator cuff repair, distal clavicle resection, shoulder dislocation, and synovectomy.
- Document both components of conservative care and justification if an exception applies.
Include required documentation elements in the record
Medical records must document that the medical necessity criteria for the specific indication are met, including presenting symptoms, positive physical exam findings, imaging results, and trials of conservative management with durations.
- Include presenting symptoms and the specific positive orthopedic test(s) referenced for the indication (e.g., Hawkins-Kennedy, Drop arm, Cross-Body Adduction).
- Attach imaging reports (x-ray preferred for AC separation; MRI when soft-tissue assessment is needed) and note PT/home exercise trial duration (minimum 6 weeks where required).
Document 3 months of failed non-operative care and ≥6 weeks PT
Document three months of failed non-operative management (NSAIDs, acetaminophen, intra-articular corticosteroid when appropriate) and a trial of PT and/or directed home exercise for at least 6 weeks where required.
- Record dates, agents used, response to therapy, and PT/home exercise details and duration.
- Note exceptions such as acute traumatic complete tears where conservative management may not be required.
Provide synovectomy-specific documentation (symptoms + imaging/biopsy + diagnosis)
For shoulder arthrotomy for synovectomy, document presence of one or more listed symptoms (joint pain, locking, pain with ROM, limited ROM, crepitus, or effusion) and include imaging or biopsy demonstrating pathology consistent with the reported condition plus a listed diagnosis.
- Include the specific diagnosis from the enumerated list (e.g., inflammatory arthritis, PVNS, synovial chondromatosis, hemochromatosis, hemophilia, Lyme synovitis, recurrent hemarthrosis).
- Attach imaging or biopsy reports that corroborate synovitis or joint effusion.
Ensure medical record documents trials/failures and additional testing
Document trials and failures of specified conservative measures (both medication and physical therapy) and any additional testing results required per indication; these records should support the indication-specific criteria cited in the policy history.
- When additional diagnostic testing is required per indication (e.g., MRI for instability, imaging for impingement or AC arthritis), include results in the submission.
- Ensure documentation aligns with the policy's enumerated criteria for the chosen CPT code.
Avoid requesting procedures for indications not listed in the policy
All indications not listed in the policy or clinical situations not described above are considered not medically necessary and may be denied; confirm that the requested procedure matches one of the policy's covered indications.
- If the clinical scenario is not described in the policy, include clear rationale and supporting evidence if requesting an exception.
- Services for deleted indications in the policy history may not be covered.
Denial risk if conservative care not documented or insufficient
Lack of documentation of three months of failed conservative management or absence of a trial of PT/directed home exercise for at least 6 weeks where required may result in claim denial.
- Verify that medication trials, injections, and PT/home exercise durations are explicitly recorded.
- Include objective notes on response or failure to conservative measures.
Denial risk for missing synovectomy symptom or imaging/biopsy evidence
For synovectomy, absence of required symptom documentation or missing imaging/biopsy evidence of underlying pathology consistent with synovitis/effusion and lack of an enumerated diagnosis increases the risk of denial.
Denial risk for missing pre-procedural conservative and testing requirements
Failure to document required conservative management (both medication trial and physical measures) or to provide required additional testing where specified may lead to claim denial for certain indications.
- This dual conservative requirement was added in the policy revision and applies to multiple indications including acromioplasty, rotator cuff repair, distal clavicle resection, shoulder dislocation, and synovectomy.
- Confirm that the submission contains both medication trial records and PT/home exercise documentation, plus any indicated imaging or testing.
Background and Rationale
Open shoulder arthrotomy permits direct visualization and treatment of intra‑articular pathology when less invasive methods are inadequate. It is particularly useful for removal of loose bodies, biopsy, addressing large bony defects, and performing procedures such as Latarjet or open Bankart repair when arthroscopic techniques are insufficient. Open procedures typically require larger incisions and may involve longer recovery and rehabilitation compared with arthroscopic approaches; therefore, they are generally reserved for complex, high‑risk, or revision cases where precise anatomic restoration is required.
