Pneumatic Compression Devices — NCD 225 | CMS Coverage Update

TL;DR: The Centers for Medicare & Medicaid Services modified NCD 225, the National Coverage Determination governing Medicare coverage of pneumatic compression devices, effective March 7, 2026. Here's what billing teams need to know before submitting claims.

This update to the CMS pneumatic compression device coverage policy clarifies the medical necessity criteria, conservative therapy trial requirements, and device-type distinctions that determine whether a claim pays or gets denied. The policy does not list specific CPT or HCPCS codes in the version data available — HCPCS code E0652 is referenced in the policy narrative for segmented, calibrated gradient devices. Review your charge capture and documentation protocols now, before the effective date of March 7, 2026.

CMS Pneumatic Compression Device Coverage Criteria and Medical Necessity Requirements 2026

NCD 225 is the National Coverage Determination governing Medicare coverage of pneumatic compression devices for home use. CMS covers these devices under the durable medical equipment benefit category — but only for two specific indications, and only when strict medical necessity criteria are met.

The two covered indications are lymphedema and chronic venous insufficiency (CVI) with venous stasis ulcers. Everything else is not covered. That's a narrow window, and CMS spells out exactly what you need to document before a device goes home with a patient.

Lymphedema Coverage Criteria

For lymphedema, the patient must complete a four-week trial of conservative therapy before pneumatic compression device coverage kicks in. The treating physician must then determine that there has been no significant improvement — or that significant symptoms remain — after that trial.

The four-week trial is not optional. It must include all three of the following:

#	Covered Indication Copy
1	An appropriate compression bandage system or compression garment (prefabricated or custom-fabricated, with adequate graduated compression)
2	Exercise
3	Elevation of the limb

If your documentation doesn't show all three components of the conservative therapy trial, expect a claim denial. CMS auditors look for this specifically.

Chronic Venous Insufficiency Coverage Criteria

For CVI, the bar is higher. The patient must have one or more venous stasis ulcers that have failed to heal after a six-month trial of conservative therapy directed by the treating physician.

That six-month trial must include:

Six months is a long time. Make sure the medical record shows the full timeline, including wound measurements and dressing changes, before the physician prescribes the device.

General Medical Necessity Requirements

Regardless of indication, CMS requires physician oversight throughout the entire process. The treating physician must evaluate the patient's condition, confirm medical necessity, instruct the patient on device operation, define a treatment plan with specific pressure settings and frequency/duration of use, and monitor the patient's ongoing response.

The medical necessity determination itself must include four elements:

That fourth element matters more than most billing teams realize. The clinical response includes the change in pre-treatment measurements, the patient's ability to tolerate the treatment session, and the patient's (or caregiver's) ability to apply the device at home. If the initial treatment response isn't documented, the claim is exposed.

Prior Authorization and Physician Prescription Requirements

The coverage policy requires a physician prescription — this device is not covered without one. Prior authorization is not explicitly called out in NCD 225 itself, but your Medicare Administrative Contractor may impose additional requirements at the local level through a local coverage determination (LCD). Check with your MAC before assuming NCD 225 alone governs your claims.

This is especially true for DME suppliers billing for these devices in the home setting. Reimbursement depends on meeting both the national and any applicable local criteria.

CMS Pneumatic Compression Device Exclusions and Non-Covered Indications

CMS covers pneumatic compression devices only for lymphedema and CVI with venous stasis ulcers. Any other indication is not covered under this policy.

The policy also draws a sharp line around device type. HCPCS code E0652 — the segmented, calibrated gradient pneumatic compression device — is only covered in specific circumstances. The policy narrative indicates this device type has a higher coverage threshold than standard devices. If you're billing E0652, confirm that your documentation supports the distinct criteria for that device type, not just the general lymphedema or CVI criteria.

Devices that don't meet the physician oversight requirements — prescription, treatment plan, initial clinical response documentation — are not covered regardless of the patient's diagnosis.

CMS Pneumatic Compression Device Billing Guidelines and Action Items 2026

This policy change has real financial exposure for DME suppliers, wound care programs, and any practice that prescribes these devices for home use. Here's what to do before March 7, 2026.

Copy Action Items

If you're billing a significant volume of these claims and you're not confident your documentation protocols cover the NCD 225 criteria, loop in your compliance officer before the March 7, 2026 effective date. The conservative therapy trial requirements alone generate a significant share of claim denials on these devices.

CPT, HCPCS, and ICD-10 Codes for Pneumatic Compression Devices Under NCD 225

The policy data available for NCD 225 in the March 7, 2026 update does not include a complete code list. The policy narrative references one HCPCS code directly.

HCPCS Codes Referenced in NCD 225 Policy Narrative

Code	Type	Description Copy
E0652	HCPCS	Segmented, calibrated gradient pneumatic compression device — covered only under specific criteria per NCD 225

Note: The NCD 225 policy data does not include additional CPT, HCPCS, or ICD-10 codes in this version. Your MAC's local coverage determination for pneumatic compression devices will likely carry a more complete code list — including standard device codes and applicable ICD-10-CM diagnosis codes for lymphedema and chronic venous insufficiency. Pull that LCD and cross-reference it against this NCD before submitting claims.

Do not assume that codes not listed in this policy are automatically excluded. The absence of a code list in NCD 225 means you need to verify at the local level.
