No material clinical or coverage changes in this revision.
Coverage Criteria for Upper Limb Prostheses
Body-Powered Upper Limb Prosthesis
Covered when ALL of the following are met:
Myoelectric Upper Limb Prosthesis
Covered when InterQual® criteria (as customized by the plan) are met:
General coverage stance
Policy covers both body-powered and myoelectric upper limb prostheses; device selection depends on clinical criteria and InterQual® subsets where referenced.
Literature does not establish clear superiority between technologies; InterQual® subset is used for myoelectric determinations and may contain plan-customized exclusions.
Requests for upper limb prostheses will be denied when the device or component will not improve or stabilize the member's condition or improve functioning, or when it is suboptimal compared with other acceptable options that can achieve the desired outcome. Coverage is also denied when a less intensive model would adequately meet the member's medical needs and permit performance of activities of daily living. Providers should ensure the requested device is the most appropriate, least intensive, medically necessary model that meets the member's specific functional needs before submitting an authorization request.
The policy history records that exclusions were formally added in July 2019. The document also documents ongoing linkage between the Plan's coverage rules and InterQual® subsets for myoelectric devices, and notes multiple subsequent updates to InterQual®–related language and criteria in later ad hoc and annual reviews.
Devices, components, or features that are intended primarily for convenience (for example, swim or shower prostheses), are solely cosmetic, are intended mainly for recreational or avocational use, or are considered experimental or investigational under the Plan's experimental policy are treated as not medically necessary and are not covered.
For myoelectric prostheses, medical necessity determinations rely on the Plan's customized InterQual® 'Prosthetics, Myoelectric, Upper Extremity' subset. Where the customized InterQual® subset excludes a device or indication, the policy treats that exclusion as not medically necessary under the Plan. Providers must follow the InterQual® criteria and the policy's stated hierarchy when requesting coverage for myoelectric devices.

Provider Actions — Prior Authorization, Documentation, and Denial Risks
Prior authorization required (general)
Obtain prior authorization before providing upper limb prostheses for most Mass General Brigham Health Plan products; specific HCPCS codes L6694, L6695, L7366, and L7368 are listed as not requiring prior authorization for some plan variations.
Obtain prior authorization per updated table
Follow the policy’s updated prior authorization table and submit prior authorization requests for the listed HCPCS codes and member product as specified; prior authorization requirements were updated and now apply per the table.
- Providers must obtain prior authorization per the policy’s updated procedures and code table (codes listed in the policy).
- Updated table and product-specific variations were added in January and March 2026 updates.
Use InterQual® for myoelectric medical necessity
Use InterQual® lookup on the plan provider website to determine medical necessity for myoelectric upper limb prostheses; the plan has customized InterQual® criteria for these devices.
- Access InterQual® Criteria Lookup via MassGeneralBrighamHealthPlan.org under the Resources menu.
- Medical necessity for myoelectric devices is determined through the plan-customized InterQual® criteria.
Follow plan-customized InterQual® subsets and hierarchy
Apply the policy’s linkage to InterQual® subsets: follow the referenced InterQual® 'Prosthetics, Myoelectric, Upper Extremity' subset and the policy’s stated criteria hierarchy and exclusions where InterQual® subsets are customized by the plan.
- InterQual® subsets (customized by the plan) contain additional literature and exclusion language referenced by the policy.
- Policy notes clarify criteria hierarchy and exclusions for customized InterQual® subsets.
Submit comprehensive, member-specific clinical documentation
Include member-specific clinical documentation with prior authorization and coordinate submission through a contracted prosthetics provider; required documentation includes medical/surgical history, co-morbid conditions, BMI, prior functional status, prior treatments/outcomes, and evidence of functional need.
- Treating physiatrist should coordinate with a contracted Mass General Brigham Health Plan prosthetics provider (prosthetist certified by ABC or BOC) to gather and submit documentation.
- Documentation must support the functional need and the member’s ability to safely use the prosthesis (weight, stability, cognitive/physical capabilities).
Follow product-specific prior authorization rules
Confirm and follow product-specific prior authorization and variation language for the member’s product (e.g., One Care, SCO, MassHealth, Medicare Advantage, Commercial) — the policy includes product-specific variations and updates that affect authorization.
- Prior authorization requirements and applicable codes may vary by product; providers must follow the rules for the member’s specific product.
- One Care/SCO and ACO sections explicitly note product variations and hierarchy where Medicare or MassHealth guidance is applied.
Avoid requests for excluded or non-improving devices
Do not request coverage for devices or features that will not improve or stabilize the member’s condition, are suboptimal versus other options, or are primarily for convenience or cosmetic purposes; such requests will be excluded or denied.
- Exclusions include devices that are primarily for convenience (e.g., swim or shower prostheses), cosmetic-only limbs/parts, recreational use, or considered experimental/investigational.
- Requests will be denied if a less intensive model adequately meets the member’s needs or if the device won’t produce the desired functional outcome.
Confirm product-specific coverage/coding to avoid denial
Verify coverage and coding requirements for the member’s specific product (Medicare Advantage, MassHealth, One Care, SCO, Commercial); failure to follow product-specific prior authorization or variation language may result in claim denial or noncoverage.
- Policy history and sections note Medicare, MassHealth, One Care/SCO, ACO, and Commercial variations that affect coverage and prior authorization.
- Providers must follow the applicable product variation language when submitting requests to avoid denials.
Background and Clinical Context
Upper limb prostheses are prescribed to replace absent limbs or parts with the goal of restoring function for activities of daily living (ADLs). Clinical assessment should include evaluation of residual limb maturity, medical and surgical history, co-morbidities, body habitus, prior functional status, and the member’s cognitive and physical ability to use and manage the prosthesis. Device selection (body-powered versus myoelectric) is based on those clinical factors, the member’s functional needs and preferences, and—where applicable—the InterQual® myoelectric subset; literature has not established clear superiority of one technology over the other.
