Coverage and Medical Necessity Criteria

Medically necessary indications by procedure

Covered when ALL of the following are met for the selected procedure:

General requirement

Procedure selection: One or more of the following procedures: hemiarthroplasty, total shoulder arthroplasty, reverse shoulder arthroplasty, or revision/replacement

Hemiarthroplasty indications: If hemiarthroplasty chosen, there must be malignancy involving the glenohumeral joint or surrounding soft tissue OR proximal humerus fracture not amenable to internal fixation OR advanced joint disease meeting the advanced joint disease subcriteria

Total shoulder arthroplasty indications: If total shoulder arthroplasty chosen, there must be malignancy involving the glenohumeral joint or surrounding soft tissue OR advanced joint disease meeting the advanced joint disease subcriteria

Reverse shoulder arthroplasty indications: If reverse shoulder arthroplasty chosen, indication may be reconstruction after tumor resection; glenohumeral osteoarthritis with irreparable rotator cuff tear; failed hemiarthroplasty; failed total shoulder arthroplasty with non-repairable rotator cuff; unreconstructable or non-repairable fracture; OR advanced joint disease with deficient rotator cuff and limited active flexion to 90 degrees against gravity plus the advanced joint disease subcriteria

Revision/replacement indications: Revision or replacement indicated for aseptic loosening of one or more prosthetic components confirmed by imaging; fracture of one or more prosthetic components confirmed by imaging; periprosthetic infection confirmed by gram stain and culture; instability of the glenoid or humeral components; or migration of the humeral head. Requires documentation of the specific finding

Advanced joint disease subcriteria: Presence of one or more of the following conditions: osteoarthritis, rheumatoid arthritis, avascular necrosis, post-traumatic arthritis, osteonecrosis of the humeral head without glenoid involvement, rotator cuff tear arthropathy, or inadequate glenoid bone stock; AND limited range of motion or crepitus on physical examination; AND pain and loss of function of at least 6 months' duration that interferes with daily activities; AND radiographic evidence of destructive degenerative joint disease with two or more of the following findings: irregular joint surfaces, glenoid sclerosis, osteophyte changes, flattened glenoid, cystic changes in the humeral head, joint space narrowing>= 6 months; radiographic >= 2 findings

The following conditions are explicitly excluded and may result in denial of shoulder joint replacement: active infection of the joint, active systemic bacteremia, and active skin infection or open wound within the planned surgical site (with the exception of recurrent cutaneous Staphylococcus infections). Also excluded are rapidly progressive neurologic disease. These exclusions apply to all shoulder arthroplasty procedures and must be documented and addressed prior to authorization.

Total shoulder arthroplasty or hemiarthroplasty performed under conditions that would place excessive stress on the implant are not covered. Examples include, but are not limited to, Charcot joint and paralytic conditions of the shoulder. Presence of these conditions is a contraindication to coverage and should be documented to avoid authorization denial.

Clinical Parameters and Coding-related Notes

inv-04: HbA1c — elevated threshold and optimization note

Threshold> 8.5%

Recommended actionEvery effort should be made to optimize glycemic levels prior to elective surgery

If not optimizedDocumented discussion by surgeon of increased risks associated with joint replacement

inv-05: Tobacco abstinence — recommendation prior to elective surgery

Recommended abstinence periodAt least 6 weeks prior to surgery

Alternative for active smokersDocument that provider reviewed benefits of smoking cessation prior to elective surgery

Provider Requirements and Prior Authorization

Prior Authorization

Preauthorization required

Preauthorization is required for shoulder joint replacement services; submit a prior authorization request before scheduling the procedure.

Step Therapy

Document ≥3 months of conservative therapy

Provide documentation of a reasonable attempt at conservative therapy for at least 3 months that includes start and end dates and results, and at least two non-surgical strategies (e.g., activity modification, physical therapy, home exercise program, anti-inflammatory/analgesic medications, or corticosteroid injections).

Documentation must establish history of conservative therapy during current episode of care for a period of 3 months.
Include start and concluding date of each therapy and results.
Include a combination of strategies and at least two of the listed approaches.
If conservative management is not appropriate, document the reason.

Background

Shoulder arthroplasty is considered when nonoperative management fails to control pain or functional loss from destructive joint disease. Indications include intractable pain, unacceptable functional decline, and radiographic evidence of degenerative joint destruction after failure of nonsurgical approaches. Reverse shoulder arthroplasty is specifically used when the rotator cuff is irreparable and the deltoid must be relied upon for arm elevation.

Common procedures include hemiarthroplasty (replacement of the humeral head with a metal ball and stem), anatomic total shoulder arthroplasty (metal humeral component with a plastic glenoid component), and reverse shoulder arthroplasty (glenoid-sided metal ball with a humeral-sided socket) — selection depends on pathology such as rotator cuff integrity, bone stock, and prior implants or fractures.

Before elective shoulder arthroplasty, the plan of care should show adequate conservative management (therapeutic home exercise, medications, and/or injections), assessment of comorbidities including glycemic control (attempts to optimize if HbA1c > 8.5%), and documentation of the absence of active infection or other contraindicating conditions. Preauthorization is required for shoulder joint replacement services.

Definitions

inv-14: Hemiarthroplasty definition

DefinitionReplacement of the humeral head with a metal ball and stem

Component noteSimilar to the component used in a total shoulder replacement

Procedure typePartial shoulder arthroplasty involving only the humeral side

inv-15: Reverse shoulder arthroplasty definition

DefinitionA metal ball is attached to the glenoid (shoulder blade) and a plastic socket is attached to the humerus (upper arm bone)

Functional effectEnables the deltoid muscle to elevate the arm instead of a torn rotator cuff

Smoking cessation appears to improve wound healing and postoperative pulmonary recovery

Documentation Required

Required clinical documentation to submit

Submit clinical documentation that includes anticipated functional demands, deltoid muscle integrity, adequacy of bone stock to allow firm fixation of implant, symptom duration and severity, specific functional limitations, types and duration of all therapeutic measures (with start/end dates and outcomes), and evidence of compliance with a documented plan of therapy.

State anticipated level of function and that it places limited demands on the shoulder.
Confirm deltoid muscle is intact.
Document adequacy of bone stock for selected implant fixation.
Provide symptom duration and severity and specific functional limitations.
Include type, duration, start/end dates, and outcomes of all therapies and therapy progress notes where applicable.

Documentation Required

Document clinical assessment within 3 months

Provide a documented clinical assessment by the requesting provider within 3 months of the prior authorization request; this assessment must be in the medical record.

Assessment must be by the requesting provider and dated within 3 months of the request.

Documentation Required

Document comorbidity optimization (diabetes, smoking)

For members with diabetes, document attempts to optimize glycemic control (aim for HbA1c ≤ 8.5% if possible) prior to elective surgery, or document that the surgeon reviewed the increased risks if optimization was not achievable; for smokers, document review of smoking cessation benefits or abstinence for at least 6 weeks prior to surgery.

If HbA1c > 8.5%, document efforts to optimize prior to elective surgery or documented discussion of increased risks with the member.
Document smoking cessation counseling or at least 6 weeks of tobacco abstinence prior to surgery (recommended).

Documentation Required

Include injection procedure report and outcomes

If intraarticular corticosteroid injections are used as part of conservative therapy, include the procedure report and documentation of outcomes in the medical record.

Procedure report submission is required for intraarticular corticosteroid injections.
Document outcomes of the injection therapy, including dates.

Denial Risk

Absolute contraindications / denial-risk conditions

Do not proceed with shoulder joint replacement when exclusionary conditions are present; these are grounds for denial.
