Certificate of Medical Necessity (CMN) for Lymphedema Pump

A form-based certificate of medical necessity outlining clinical information required to justify coverage of a lymphedema (pneumatic) pump, including diagnosis, clinical findings, prior conservative therapy, trial duration, pump settings, and provider attestation/documentation requirements.

Coverage Summary

A form-based Certificate of Medical Necessity used to collect the clinical details required to justify coverage of a lymphedema (pneumatic) pump. The CMN documents the diagnosis and clinical findings, prior conservative therapy and its trial duration, expected frequency and duration of pump use, pump pressure settings, and requires provider attestation and supporting documentation. Coverage stance: mixed — coverage is supported when the specified CMN fields and documentation requirements are met.

Quick facts and thresholds

Conservative therapy trial (lymphedema)4 weeks

Conservative therapy trial (CVI)6 months

Core clinical criteria groups3

Medical Necessity Criteria (CMN)

General CMN clinical criteria

Coverage supported when ALL of the following are met:

Diagnosis/Condition: Documented diagnosis/condition that warrants use of a lymphedema pump (filled on CMN)
Clinical findings described (filled on CMN)
Expected frequency of use specified (filled on CMN)
Expected duration of use specified (filled on CMN)
Pump pressures to be used are specified (filled on CMN)
Typed office note with pertinent information is provided
Physician signature (stamps not acceptable) on the CMN

Prior conservative therapy for lymphedema

Coverage supported when ALL of the following are met:

Conservative therapy definition: Conservative therapy includes appropriate compression bandage system or compression garment, exercise, and elevation of the limb
4-week trial: Four-week trial of conservative therapy has been attempted4 weeks
No improvement: No significant improvement after the four-week trial

Provider Actions / Documentation Requirements

Documentation Required

Complete CMN fields

Provider must complete CMN fields including diagnosis, clinical findings, expected frequency and duration of pump use, pump pressures, and sign the form (physician signature required; stamps not acceptable).

Documentation Required

Attach supporting office note

Provider must attach a typed office note with pertinent information and additional clinical rationale to support medical necessity.

Prior Authorization

Prior conservative therapy requirement

Provider must document trial and failure of conservative therapy before coverage is supported. For lymphedema this requires a four-week trial (including appropriate compression bandage or garment, exercise, and limb elevation) with no significant improvement. For chronic venous insufficiency (CVI), six months of conservative therapy must have been tried and failed (and presence of one or more non-healing venous stasis ulcers is queried on the CMN).

Lymphedema: 4 weeks
CVI: 6 months

Background & Definitions

The CMN template is designed to collect specific clinical information to determine medical necessity for a lymphedema pump: the patient diagnosis/condition, clinical findings, expected frequency and duration of use, and pump pressures. It requires documentation of prior conservative management (a four-week trial for lymphedema; six months if CVI), a typed office note with pertinent clinical rationale attached, and a physician signature on the CMN (stamps are not acceptable).

Conservative therapy: Use of an appropriate compression bandage system or compression garment, exercise, and elevation of the limb.
