Coverage and Medical Necessity Criteria

General medical necessity criteria

Prosthesis is proven and medically necessary when ALL of the following criteria are met:

General upper extremity prosthesis medical necessity: Member has a traumatic or surgical amputation of the upper extremity or a congenital absence or defect; and the prosthetic replaces all or part of the missing limb; and the prosthetic will help the member regain or maintain function; and the prosthetic device is ordered by or under the direction of a physician; and the prosthetic needs are evaluated for the member by a healthcare professional with appropriate prosthetic qualifications and training under the supervision of the ordering physician; and the member is willing and able to participate in training for use of the prosthetic; and the member with expected rehabilitation potential undergoes functional assessment including Activities of Daily Living (ADLs) and Instrumental ADLs (IADLs).

Applies to initial or replacement external prosthetic devices; benefits limited to external prostheses (not fully implanted).

Myoelectric prosthesis (below wrist) criteria

Myoelectric prosthetic hand, partial-hand, or artificial digit(s) for amputations below the wrist is medically necessary when ALL of the following are met:

Myoelectric below-wrist criteria: Member has a traumatic or surgical amputation below the wrist or a congenital missing or dysfunctional hand or finger; and the prosthetic replaces all or part of the missing limb; and the prosthetic will help the member regain or maintain function; and the prosthetic needs are evaluated for the member by a healthcare professional with appropriate prosthetic qualifications and training under the supervision of the ordering physician; and the member is willing and able to participate in training for use of the prosthetic; and the member is able to operate the simulator of the computerized prosthetic or microprocessor; and the member with expected rehabilitation potential undergoes functional assessment including ADLs and IADLs; and the remaining musculature contains sufficient myoelectric signal (minimum microvolt threshold across multiple muscle groups, usually 3–5) to allow operation of the myoelectric device; and the ordering physician authorizes the final prosthetic proposal.minimum EMG signal across multiple muscle groups (usually 3-5)

Myoelectric prosthetic components below the wrist are not medically necessary if these criteria are not met.

Myoelectric prosthesis (above wrist) criteria

Myoelectric prosthetic for amputations above the wrist:

Above-wrist myoelectric: Medical necessity clinical coverage criteria for myoelectric prostheses above the wrist are determined by InterQual CP: Durable Medical Equipment, Prosthetics, Myoelectric, Upper Extremity, Above the Wrist (Custom) - UHG; providers should refer to InterQual criteria for authorization decisions.

Policy references InterQual for detailed above-wrist criteria.

Bone‑anchored (osseointegrated) prostheses — evidence and coverage considerations

Evidence summary and coverage stance:

Osseointegrated (bone‑anchored) transhumeral prostheses: Available clinical evidence is limited in quantity and quality, consisting mainly of small case series and retrospective analyses; comparative studies are lacking and overall evidence is insufficient to broadly support routine coverage.

Reported outcomes: Some case series and small prospective reports describe improved range of motion, prosthetic control, and patient‑reported satisfaction; neuromusculoskeletal interfaces have shown long‑term functional use in very small cohorts (3–7 years follow‑up reported in select series).

Risks: Studies report substantial rates of skin‑penetration site infections and other complications (one series reported a 38% incidence of infectious complications at 5 years) and device failures/revisions; implant survival in TH cohorts has been reported at approximately 83% at 2 years and 80% at 5 years.

Implication for coverage:

Myoelectric and multi‑grip hands, and powered wrists — evidence and coverage considerations

Evidence summary and coverage stance for externally powered upper‑extremity devices:

Functional benefit: Small studies demonstrate potential functional improvements (for example, decreased task failure and reduced compensatory movements with powered wrists in a 3‑subject study) but results are mixed for multi‑grip myoelectric hands versus standard single‑grip hands (a comparative study of n=33 showed no clear consistent benefit and in some measures the single‑grip device outperformed multi‑grip).

Evidence quality: Overall the body of evidence is small, heterogeneous, and generally low to very low quality; technology assessments (ECRI, Hayes) conclude current evidence is insufficient for definitive conclusions for many advanced externally powered devices.

Implication for coverage: Consider individualized coverage when objective documentation demonstrates functional need and less complex or lower‑cost devices have been tried or are unsuitable; account for device cost, durability, training needs, and require documentation of objective functional deficits and prior device history when approving advanced myoelectric or multi‑grip devices.

In absence of documented functional advantage, multi‑grip devices may be considered not medically necessary.

Claims for prosthetic items that are intended primarily as safety items or to enhance sports-related performance are excluded from coverage. In addition, repair or replacement of prosthetic devices will be denied when the need arises from misuse, malicious damage, gross neglect, or to replace lost or stolen items. Benefits apply only to external prosthetic devices and do not extend to fully implanted devices under the external prosthesis benefit category; internal implants are handled under the applicable medical/surgical benefit.

Bone-anchored percutaneous limb prostheses (for example, the OPRA Implant System) are considered unproven and not medically necessary due to insufficient evidence of efficacy and safety, including reports of high infection and mechanical complication rates. The policy therefore does not support routine coverage for these devices.

Excluded from coverage are devices provided primarily as safety items or to enhance sports performance. Likewise, repair or replacement claims arising from misuse, malicious damage, gross neglect, or lost/stolen items are not eligible for benefits. These exclusions apply in addition to the policy requirement that the prosthesis be medically necessary and ordered and supervised by an appropriate clinician.

The evidence base for multi‑grip myoelectric hands is limited and inconsistent. Small comparative studies and single-case series report mixed results: some users report improved satisfaction or task performance with multi‑grip devices, while controlled comparisons have failed to show consistent superiority and in some measures the standard single‑grip prosthesis outperformed multi‑grip devices. Overall, the literature is small, heterogeneous, and of low quality, so expected functional gains from multi‑grip hands are uncertain.

Myoelectric prosthetic components for a hand, partial-hand, or artificial digits below the wrist are considered not medically necessary when the member does not meet the specified device criteria — for example, inability to operate the simulator, insufficient EMG signal (below the minimum multi‑site threshold), lack of training or functional potential, or failure to meet other listed clinical requirements.

Overall, bone‑anchored (osseointegrated) devices are treated as investigational/unproven in many clinical contexts because available studies are limited and low quality and report substantial safety concerns, including high rates of skin‑penetration site infections and device complications. Reported implant survivorship is variable and infection incidence in some transhumeral series is notably high, which supports a cautious, case‑by‑case approach rather than routine coverage.

Comparative studies summarized in the literature did not demonstrate a clear, consistent functional advantage for multi‑grip myoelectric hands over standard single‑grip myoelectric prostheses. One comparative study (n=33) found no clear benefit for multi‑grip devices and reported that the standard single‑grip prosthesis outperformed the multi‑grip device on several outcome measures. Case series and small studies report mixed findings and highlight limitations such as small sample sizes and lack of randomization.

Myoelectric minimum muscle groups — activation threshold for computerized hand

Minimum activatable muscle groupsUsually 3–5 residual muscle groups with measurable microvolt EMG signals must be activatable to operate a computerized/myoelectric hand.

Purpose of thresholdEnsures remaining musculature contains sufficient myoelectric signal to operate the prosthesis (no external switch).

Assessment requiredMember must be able to operate the simulator of the computerized prosthetic or microprocessor to demonstrate control prior to provision.

DocumentationClinical records should document EMG capability across the specified muscle groups and simulator performance as part of medical necessity review.

Prior Authorization, Documentation, and Billing Guidance

Prior Authorization

Prior authorization required for osseointegration

Prior authorization is required for osseointegration (bone-anchored percutaneous limb prostheses) due to substantial rates of infection, variable implant survival, and limited comparative evidence. Obtain prior authorization before scheduling osseointegration procedures.

Osseointegration/OPRA and similar procedures
Transhumeral (TH) osseointegrated implant procedures

Billing Rule

Lowest-cost reasonable alternative payment expectation

When multiple prosthetic devices could meet the member's functional needs, benefits are limited to the device that meets the minimum specifications. If a member chooses a higher-cost device, payment is limited to the allowance for the lowest-cost reasonable alternative and the member is responsible for the difference.

Background and Evidence Summary

Upper limb prostheses can be classified as passive, body‑powered, externally powered (myoelectric), or hybrid. Coverage for an initial or replacement external prosthetic device requires that the device replace all or part of a missing limb, be medically necessary per the member's benefit plan, and not be excluded by plan terms. The policy requires clinician direction and prosthetic professional evaluation, documented functional need (including ADLs/IADLs), and that, when multiple devices could meet needs, payment is limited to the device meeting minimum specifications.

Definitions and Abbreviations

Activities of Daily Living (ADLs)

DefinitionBasic tasks needed for personal self-care and daily functioning such as bathing, grooming, dressing, toilet use, eating, and physical ambulation.

On This Page

Use may be considered only in highly selected transhumeral amputees (e.g., trauma/tumor patients with inability to tolerate sockets or very short residual limb) after documented prior socket attempts and counseling; documentation should include indication, prior prosthetic history, informed consent about infection and revision risk, and consideration of non‑osseointegrated alternatives.

Osseointegrated percutaneous limb prostheses (e.g., OPRA) are considered unproven and not medically necessary for routine coverage due to insufficient evidence and safety concerns.

Payment limited to device meeting minimum specifications
Member responsible for cost difference if selecting upgraded device

Note

Clinical benefit and cost considerations

Clinical benefit of advanced, multi-grip, or osseointegrated prostheses is uncertain and should be weighed against cost and repair burden. Prescribers should document why a higher-cost or advanced device is expected to provide additional functional benefit over simpler alternatives.

Evaluate comparative benefit vs. single-grip or body-powered devices
Consider long-term repair/maintenance costs in decision-making

Denial Risk

Inconclusive benefit / utilization concerns

Evidence for multi-grip myoelectric hands is inconclusive and utilization may not match patient expectations. Expect utilization review and careful justification when prescribing multi-grip devices.

Potential mismatch between desired features and real-world use
Consider structured training and documented trials prior to approval

Documentation Required

Required documentation for medical necessity review

Medical records and clinical documentation may be required for medical necessity review. Provide objective evidence of amputation or congenital absence, prior prosthetic trials, functional assessments, and documentation of comorbidities that affect candidacy.

Operative report or diagnosis documenting amputation/congenital absence
History of prior prosthesis use and reason for change (e.g., socket intolerance)
Records of infections or residual limb complications

Documentation Required

Clinical eligibility considerations

Clinical eligibility for advanced procedures (e.g., osseointegration) should document exclusion of conditions associated with poorer outcomes. Patients with peripheral vascular disease, uncontrolled diabetes, or active residual limb infection are generally not candidates.

Exclude: peripheral vascular disease (PVD), uncontrolled diabetes mellitus, active residual limb infection
Prefer candidates with traumatic or tumor-related amputations and failed/poor tolerance of socket prostheses

Documentation Required

Required comprehensive assessment and prescription components

A comprehensive assessment and collaborative prescription must accompany prosthesis requests. Documentation should describe present health, function, pain, cognition, goals, and a detailed device prescription including design and control strategy.

Comprehensive assessment components: present health status; level of function; modifiable risk factors; pain assessment; cognition/behavioral health; social context; learning assessment; residual limb and contralateral limb/trunk assessment; prosthetic assessment; vocational assessment
Prescription components: design (preparatory vs definitive); control strategy (passive, externally powered, body-powered, task specific); anatomical side and amputation level; socket interface and frame; suspension mechanism; terminal device; wrist/elbow/shoulder units as applicable
Collaborative decision note from the care team (patient input required)

Documentation Required

Functional outcome documentation

Document functional outcomes using validated measures when available (e.g., AM-ULA, DASH, PROMIS domains). Include details on completion, speed, movement quality, prosthesis wearing time, and activity-specific performance to support medical necessity and monitor benefit.

Suggested measures: AM-ULA, DASH, PROMIS Upper Extremity, PROMIS Pain Interference, SHAP
Report baseline and follow-up performance, wearing time, and patient-reported satisfaction

Step Therapy

Therapy sequence for TH amputees

For transhumeral (TH) amputees, consider a stepwise therapy sequence: attempt and document trials with conventional socket prostheses and other non‑osseointegrated options before approval of osseointegration. Osseointegration is reserved for those with inadequate function or tolerance of socket solutions.

Document failed trials or intolerance of socket prosthesis
Show evidence of pre-prosthetic training and rehabilitation efforts

Note

Consideration of simpler prosthesis options

Consider simpler prosthesis options (e.g., single‑grip myoelectric or body‑powered devices) which may be more durable, easier to train, and provide equivalent function for many activities. Justify why a simpler device is insufficient before requesting advanced or multi‑grip devices.

Single-grip myoelectric devices: lower repair burden, greater durability
Body-powered devices: advantages in training time and mechanical reliability
Document rationale why simpler options do not meet functional goals

Myoelectric Prosthetic — definition

DefinitionA prosthetic device operated by battery-powered electric motors activated through electrodes by myoelectric (EMG) potentials produced by muscles.

ComponentsTypically includes electrodes, cables, batteries/charger, control module, and motorized terminal device as described in HCPCS codes referenced in the policy.

Operational requirementRequires sufficient residual musculature EMG signal (e.g., usually 3–5 activatable muscle groups) and the ability to operate a simulator for candidacy evaluation.

Prosthetist — definition

DefinitionA healthcare professional who makes and fits artificial limbs (prostheses) for people with disabilities.

Scope of practiceIncludes evaluation, fitting, alignment, and training of prosthetic devices under physician supervision as required for coverage determinations.

Documentation roleA qualified prosthetic professional must evaluate prosthetic needs and document that evaluation for medical necessity review.

Neuromusculoskeletal interface / osseointegration

DefinitionAn implant anchored to bone (osseointegration) that enables bidirectional communication between prosthetic components and implanted electrodes in nerves/muscles, supporting intuitive control and sensory feedback.

Clinical contextUsed in neuromusculoskeletal interfaces for transhumeral amputees to allow implanted electrodes to transmit motor intent and sensory information to/from the prosthesis.

Evidence noteAvailable studies are small (e.g., 3–7 years follow-up in tiny cohorts) and report functional use but also substantial infection and complication risks requiring careful selection and consent.

Myoelectric orthosis (MyoPro 2+) — definition

DefinitionA noninvasive EMG-driven orthosis that senses patient muscle signals and converts them into orthotic movement to assist weak or partially paralyzed limbs (example: MyoPro 2+).

Intended useIntended to support and move a weak limb in patients aged ≥12 years with long-term muscle weakness or partial paralysis; evidence is limited and inconclusive.

Evidence noteECRI found no published studies specific to MyoPro 2+; evidence from small case series for related devices suggests possible benefit but is insufficient to be conclusive.

Prosthesis regulatory status

General statusMost external prostheses are Class I devices and are exempt from FDA premarket review.

Notable de novo deviceThe DEKA Arm System received FDA de novo clearance (DEN120016) in 2014 (informational only; FDA clearance alone does not determine coverage).

Regulatory notePolicy notes FDA classification for informational purposes and provides FDA links for the DEKA/DEKA (LUKE) Arm documentation.

AM-ULA — Activities Measure for Upper Limb Amputees

Measure nameActivities Measure for Upper Limb Amputees (AM-ULA).

PurposeA performance-based activity measure assessing extent of completion, speed, movement quality, prosthetic skillfulness, and independence in tasks for adult upper-limb amputees.

Use in documentationPolicy recommends documenting performance measures such as AM-ULA to support functional need in prior authorization and medical necessity reviews.
