Headrest: A headrest (HCPCS E0955) is covered when the member has an approved manual tilt-in-space, manual semi- or fully reclining back on a manual wheelchair, a manual fully reclining back on a power wheelchair, or a power tilt and/or recline power seating system.

Combination cushions: Combination skin-protection and positioning seat cushions (HCPCS E2607, E2608, E2624, E2625) are covered when the criteria for both a skin-protection seat cushion and a positioning seat cushion are met.

Custom fabricated cushions/back: Custom fabricated seat cushion (HCPCS E2609) requires that (1) the member meets all criteria for a prefabricated skin-protection or positioning seat cushion, (2) for a custom back (HCPCS E2617) the member meets all criteria for a prefabricated positioning back cushion, and (3) there is a comprehensive written evaluation by a licensed/certified PT or OT clearly explaining why prefabricated options are insufficient; the PT/OT must have no financial relationship with the supplier.

Written clinician evaluation required for custom fabrication.

inv-02: Diagnosis-supported coverage (partial)

Covered when a listed diagnosis supports medical necessity for specific HCPCS codes

Diagnosis requirement: Claims for HCPCS E2607, E2608, E2624, or E2625 are supported when the member has one of the ICD-10-CM codes listed in 'ICD-10 Table 3' of this policy segment.presence of one listed ICD-10 code

This is a partial excerpt of the full ICD-10 table.

inv-03: Diagnosis-supported medical necessity

Diagnosis codes that support medical necessity for wheelchair seating and for specific HCPCS when pressure ulcers are involved

Diagnosis code present: Presence of one of the listed ICD-10-CM diagnosis codes (including neuromuscular, neurodegenerative, congenital, cerebrovascular, amputation, musculoskeletal, and the L89.x pressure-ulcer codes or Z87.2) supports medical necessity when billed with wheelchair seating HCPCS; for pressure-ulcer–related HCPCS (E2607, E2608, E2624, E2625) an L89.x or Z87.2 diagnosis code must be billed with the claim.

Full clinical documentation requirements are in other policy sections.

inv-04: Diagnosis requirement for E2609

Diagnosis codes in ICD-10 Table 5 support medical necessity for HCPCS code E2609.

Diagnosis support for E2609: Claim or prior authorization for HCPCS E2609 must include an ICD-10-CM diagnosis from ICD-10 Table 5 to support medical necessity.

See ICD-10 Table 5 for the full list of qualifying diagnoses.

inv-05: Coverage mapping and medical necessity linkage

Policy ties coverage to listed diagnoses and to Medicare LCD/LCA guidance; ICD-10 code additions and revisions updated tables that map diagnoses to HCPCS codes.

General coverage linkage: Coverage decisions require matching appropriate ICD-10 diagnoses from the policy tables to the mapped HCPCS codes and following medical necessity documentation and member benefit limits.

Refer to the ICD-10 tables and HCPCS mappings in the policy (tables span multiple segments).

Per policy, certain seating items and accessories are explicitly listed as not medically necessary for specified situations. Examples include: general use seat or back cushions and separate positioning accessories when provided for a power-operated vehicle (POV) or a power wheelchair with a captain's chair seat, seat or back cushions intended for use with transport chairs (E1037, E1038), and the powered seat cushion (E2610) which is stated as having unestablished effectiveness. These conditions should be used to guide coverage determinations when the place of use or device type matches the examples above.

The policy requires an appropriate supporting ICD-10 diagnosis to establish medical necessity for specified HCPCS codes. Absence of any ICD-10-CM code from the policy's listed diagnosis tables (for example, the codes shown in ICD-10 Table 3) implies the provider has not submitted a documented diagnosis that supports coverage for those HCPCS codes and may result in a denial or determination of noncoverage.

Within the excerpt provided there are no additional explicit exclusion clauses beyond the not-medically-necessary examples and the requirement that certain HCPCS codes be billed with listed ICD-10 diagnoses. Where specific exclusions would apply they are addressed in other sections of the full policy; this excerpt does not introduce new explicit exclusions.

This clinical policy is a guide to medical necessity and does not supersede the terms and conditions of a member's benefit contract. Coverage decisions remain subject to plan-level benefit limits, exclusions and applicable state or federal requirements; when legal or regulatory requirements conflict with this policy, those laws govern.

The policy references specific HCPCS procedure codes in multiple contexts. Notably, E0992 is listed as a manual wheelchair accessory (solid seat insert), E2610 is identified as a powered seat cushion, and K0669 denotes a wheelchair accessory that does not meet specific code criteria or lacks PDAC coding verification. These codes are cited in the policy's not-medically-necessary list and should be verified on submissions and prior authorization requests.

For several HCPCS codes the policy explicitly ties coverage to the presence of a supporting diagnosis. If a submitted claim for a HCPCS code that requires a listed diagnosis (for example, the codes referenced in ICD-10 Table 3 or the pressure-ulcer list) does not include one of the policy-listed ICD-10-CM codes, the request is implied to be not medically necessary per the policy's coverage mapping.

This excerpt does not contain additional standalone statements that declare items not medically necessary beyond the examples and diagnostic linkage already listed. Determinations of 'not medically necessary' for other items are made according to the policy's criteria and benefit terms as detailed in the full document.

Final coverage determinations combine the policy's medical necessity criteria with the member's benefit terms and any applicable medical policy or contract provisions. Providers should understand that this clinical policy informs but does not replace plan benefit limits, exclusions, or applicable regulatory requirements when making coverage decisions.

Documentation Required

Diagnosis Requirement for Listed HCPCS Codes

When submitting prior authorization requests or claims, include an applicable ICD-10-CM diagnosis code that supports medical necessity as listed in the policy tables. Lack of a listed supporting diagnosis may result in denial.

Submit the specific ICD-10-CM code from the ICD-10 Table 2, Table 3, Table 4, or Table 5 that corresponds to the HCPCS code being requested.
If no diagnosis from the provided lists is billed with the HCPCS code, the claim may be denied for insufficient diagnosis support.

Documentation Required

Diagnosis Requirement for Specific HCPCS

HCPCS E2607, E2608, E2624, and E2625 require an associated ICD-10-CM diagnosis from the policy's Table 3 list. For pressure-ulcer related indications pair the HCPCS with an L89.x or Z87.2 code from Table 4.

E2607, E2608, E2624, E2625 — require a Table 3 diagnosis code.
For pressure ulcer cases, bill the applicable L89.x or Z87.2 diagnosis with these HCPCS codes.

Denial Risk

Pressure-Ulcer Diagnosis Requirement

For E2607, E2608, E2624, and E2625 used for patients with pressure ulcers, the applicable pressure-ulcer ICD-10-CM code (L89.x) or Z87.2 must be billed with the seating code to support medical necessity.

Bill one of the listed L89.x codes or Z87.2 with the HCPCS code when the indication is a current or past pressure ulcer.
Failure to include the pressure-ulcer diagnosis may result in claim denial.

Documentation Required

Documentation for Custom Fabrication and Diagnosis Support for E2609

E2609 (custom fabricated seat cushion) requires that the member meet the prefabricated cushion criteria AND that a comprehensive, written evaluation by a licensed PT or OT is submitted which documents why prefabricated options are insufficient. The evaluator must have no financial relationship with the supplier.

For custom fabrication (E2609/E2617) include the comprehensive written PT/OT evaluation and evidence that prefabricated devices were tried or are insufficient.
Verify coverage is consistent with the member's plan documents; PA approval does not guarantee payment if benefit exclusions apply.

Step Therapy

Step from Prefabricated to Custom — Required Documentation

When moving from a prefabricated seating system to a custom fabricated device, document why prefabricated options are insufficient. The PT/OT evaluation must clearly explain the clinical need and inability of prefabricated seating to meet the member's needs.

Step from prefabricated to custom requires meeting prefabricated criteria AND a written PT/OT evaluation explaining insufficiency of prefabricated options.
Evaluator (PT/OT) must have no financial relationship with the supplier.

DME Medical Necessity Rules

inv-62: DME medical necessity — mirrors coverage criteria for each equipment type

DME medical necessity mirrors the coverage criteria for each equipment type:

General use cushions: Covered when used with an approved manual or power wheelchair with a sling or solid seat/back.

Skin protection indications: Either current or past pressure ulcer at the contact area OR absent/impaired sensation in the contact area OR inability to perform functional weight shift due to a qualifying diagnosis supports medical necessity for skin-protection cushions.

Refer to ICD-10 tables for qualifying diagnoses.

Positioning indications: Significant postural asymmetries due to qualifying diagnoses (per policy lists) support medical necessity for positioning cushions and accessories.

Custom fabrication (E2609,E2617) requires that all prefabricated criteria are met plus a comprehensive written PT/OT evaluation explaining why prefabricated options are insufficient and the evaluator has no financial relationship with the supplier.

Written clinician evaluation required.
