Coverage Criteria and Policy Determinations

Investigational / Not Medically Necessary

The following are considered investigational (not covered) because evidence is insufficient:

Investigational devices: - Prosthetic whole hand attachments with individually powered (multiarticulating) fingers (digits) that use full or partial myoelectric power for independent movement of individual joints. - Intent decoding modules (IDMs) or pattern-recognition control add-on modules used with myoelectric upper limb prostheses. - Myoelectric partial hand prostheses with individually powered digits. - Advanced upper-limb prosthetic components with both sensor and myoelectric controls (e.g., LUKE arm). - Myoelectric-controlled upper limb orthoses (e.g., MyoPro).n/a

Designated investigational in policy; clinical evidence considered insufficient.

Coverage determinations

Coverage stance differs by device type and evidence:

Myoelectric prosthetic components at or proximal to the wrist: When passive or body-powered prostheses cannot be used or are insufficient to meet functional needs, myoelectric components for persons with amputation at the wrist or above may be considered; available evidence is sufficient to determine improvement in net health outcome for some myoelectric components.

Based on limited comparative data indicating similar capability to body-powered prostheses for light work and advantages in appearance

Advanced sensor and myoelectric-controlled prostheses: Evidence for sensor-plus-myoelectric controlled upper-limb prostheses is mixed; study results are inconsistent and insufficient to determine improvement in net health outcome for current generation devices.

Further study needed

Myoelectric prostheses with individually powered digits (partial hand): Considered investigational due to lack of peer-reviewed publications evaluating functional outcomes.

Investigational statement added 10/01/22

Myoelectric powered upper-limb orthoses (e.g., MyoPro): Evidence is insufficient to determine that myoelectric orthoses improve net health outcome; small, inconsistent studies (largest N=18) and lack of training in studies limit conclusions—considered investigational.

Investigational statement added in prior reviews

Intent decoding modules / pattern recognition add-ons: Intent decoding modules (IDMs) or pattern-recognition control add-on modules used with myoelectric upper limb prostheses are considered investigational.

Added 04/01/25 interim review

Custom fabricated gloves for an upper extremity prosthesis (HCPCS L6895) are considered not medically necessary. The policy states these gloves are "not primarily medical in nature," and therefore are excluded from coverage.

Gloves for upper extremity prostheses are listed in the policy history as not medically necessary. Documentation of this coding and exclusion is reflected in the policy updates and coding history.

Myoelectric upper limb prosthetic components are not medically necessary when the required medical necessity criteria in this policy are not met. The medical record must document all required elements including: (1) amputation or missing limb at the wrist or above; (2) trial of or inability to use standard body-powered prosthetic devices; (3) remaining musculature meets the minimum microvolt threshold to operate a myoelectric device; (4) sufficient neurologic and cognitive function; (5) absence of comorbidities that would interfere with prosthesis function; and (6) a functional evaluation indicating likely benefit with training.

Myoelectric orthoses and advanced prostheses that combine sensor and myoelectric controls are designated investigational due to insufficient and inconsistent evidence. The policy cites small, inconsistent studies (largest identified study N=18) and mixed results for advanced sensor/myoelectric devices, concluding the evidence is insufficient to demonstrate improved net health outcomes; devices and components designated investigational are not covered.

Provider Steps, Documentation, and Billing Requirements

Prior Authorization

Prior Authorization / Review Required

Prior authorization is required. Medical necessity criteria and supporting documentation must be submitted for review prior to coverage of myoelectric upper‑limb prosthetic components.

Submit detailed clinical documentation showing ALL coverage criteria are met (see Documentation callout).
Prior authorization may be required per payer rules and for appropriate use of current HCPCS codes.
Failure to obtain prior authorization when required may result in claim denial.

Billing Rule

Coding and Prior Authorization Considerations

Use current HCPCS codes when submitting claims. Certain HCPCS codes for myoelectric prosthetic components have been added, changed, or designated investigational over time — verify and submit the appropriate single code for the complete device where codes are all‑inclusive.

Background and Policy Scope

Myoelectric prostheses use amplified residual muscle electromyographic (EMG) signals from remaining musculature to drive powered motors for hand, wrist, and/or elbow movement. They can provide more natural control than body-powered devices, but appropriate candidate selection is required: the individual must have sufficient residual musculature (meeting the policy’s microvolt threshold), adequate neurologic and cognitive function, and no comorbidities that would interfere with prosthesis use. Functional evaluation and training are necessary to determine likely benefit.

Definitions and Device Examples

Intent Decoding Modules — inv-22

DefinitionIntent Decoding Modules (IDMs) are add-on components that translate surface EMG muscle signals from electrodes into prosthetic commands using pattern-recognition/machine-learning algorithms, often connecting to an app for calibration and personalization

FunctionProvide pattern-recognition control to allow more natural, fluid, and intuitive movement of hand, wrist, or elbow

ApplicationApplied and configured by a prosthetist as part of an upper‑limb myoelectric prosthesis

Partial hand myoelectric prosthesis — inv-23

DefinitionPartial hand myoelectric prosthesis is designed to replace the function of one or more missing fingers following a partial hand amputation at a transmetacarpal level or higher

Representative trials

Includes NCT06684730 (planned N=22), NCT03401762 (planned N=96), NCT05768802 (planned N=5)

Other listed studiesAlso lists trials such as an osseointegration trial with planned N=18 and others with ongoing/unknown status

Do not unbundle: L7499 (Upper Extremity Prosthesis, Not Otherwise Specified) must not be used together with L6026, L6715, L6880, or L7007‑L7009 for the same initial issue — using L7499 plus those codes is considered incorrect coding/unbundling.
New and updated codes (examples): L6700 (intent/pattern‑recognition module, effective 04/01/25), L6715, L6880, L6882, L6895, L6925‑L6965, L7180, L7181, L7499. Confirm effective dates and use current code set.
Claims for investigational devices (e.g., devices with individually powered digits, IDMs/pattern recognition add‑ons) should not be submitted as medically necessary codes — these items may be denied as investigational.

Step Therapy

Step Requirement: Trial of Body‑Powered Prosthesis

Step requirement — must demonstrate that standard body‑powered prosthetic devices cannot be used or are insufficient to meet the individual's functional needs before a myoelectric prosthesis will be considered medically necessary.

Document why a body‑powered device is not suitable or is insufficient for activities of daily living.
Functional evaluation results must indicate that with training, a myoelectric prosthesis is likely to meet the individual’s functional needs (gripping, releasing, holding, coordination).

Documentation Required

Required Clinical Documentation

Provider must submit all required clinical documentation with the prior authorization or claim. The medical record must document a detailed history and physical demonstrating that ALL coverage criteria are met.

Level of amputation at the wrist or above (forearm, elbow, etc).
Statement that standard body‑powered prosthetic devices cannot be used or are insufficient for activities of daily living.
Electromyographic evidence that remaining musculature provides minimum microvolt threshold to operate a myoelectric device.
Assessment of sufficient neurologic and cognitive function to operate the prosthesis safely and effectively.
Documentation of absence of comorbidities that could interfere with prosthesis function (eg, progressive neuromuscular disease).
Functional evaluation results indicating likelihood of meeting functional needs with training.

Denial Risk

Denial Triggers

Claims may be denied when required medical necessity criteria are not met or when incorrect coding is used.

Denial triggers include: unmet coverage criteria (see Documentation callout), use of L7499 inappropriately with all‑inclusive HCPCS codes (unbundling), or submission of investigational device codes as medically necessary.
Investigational items that may be denied: myoelectric prostheses or orthoses with individually powered digits, intent decoding modules/pattern recognition add‑ons, advanced sensor+myoelectric systems (e.g., LUKE arm), and myoelectric controlled orthoses.

Billing Rule

Use Current HCPCS Codes

Use current HCPCS codes when submitting claims and verify code effective dates. Coding updates have been made periodically; submit the single appropriate code that represents the complete device when codes are all‑inclusive.

Examples of relevant HCPCS codes (not exhaustive): L6026, L6700, L6715, L6880, L6882, L6895, L6925, L6935, L6945, L6955, L6965, L7180, L7181, L7499.
Confirm payer requirements for prior authorization and coding prior to claim submission to avoid denials or incorrect coding adjudication.

Note

Investigational Items May Be Denied

Devices or components designated investigational in this policy should not be billed as medically necessary and are subject to denial.

Investigational examples include: prosthetic whole hand attachments with individually powered digits, myoelectric partial hand prostheses with individually powered digits, intent decoding modules (IDMs) / pattern‑recognition control add‑ons, advanced sensor+myoelectric component systems, and myoelectric controlled upper‑limb orthoses.
If a device under consideration is new or uncommon, consult medical policy and payer coverage rules before authorizing or billing.
