Negative Pressure Wound Therapy (NPWT)

Coverage Reminder

An examination of the Qualified Independent Contractor (QIC) reviews for Negative Pressure Wound Therapy (NPWT) claims identified common errors in the information submitted in support of claims payment. This article will review the findings and related policy requirements.

Reasons for Denial

Insufficient documentation to indicate new/additional wounds
Insufficient documentation to substantiate payment after the fourth month of therapy

Payment Rules

New and/or Additional Wounds

There must be clear documentation in the medical records when new or additional wound(s) are being treated. Medical records should document the evaluation, location, care, and wound measurements, dressing type and frequency of change, evaluation of nutritional status, and any additional coverage criteria as stated in the NPWT LCD and Policy Article. When this documentation is missing from the medical records, the claim will most likely be denied as not reasonable and necessary. CGS developed the following additional resources to assist in determining if the medical records contain the necessary information.

Continued Coverage When Therapy Exceed 4 Months

When NPWT therapy exceeds 4 months on the most recent wound and reimbursement ends, individual consideration for one additional month at a time may be sought using the appeals process. Information from the treating practitioner's medical record, contemporaneous with each requested one-month treatment time period extension, must be submitted with each appeal explaining the special circumstances necessitating the extended month of therapy.

Note, the LCD provides coverage for the use of NPWT limited to initiating healing of the problem wounds described in the "Coverage Indications, Limitations and/or Medical Necessity" section of the related LCD rather than continuation of therapy to complete healing since there is no published medical literature demonstrating evidence of a clinical benefit for the use of NPWT to complete wound healing.

Therefore, general, vague, or nonspecific statements in the medical record such as "doing well, want to continue until healed" provide insufficient information to justify the need for extension of treatment.

The medical record must provide specific and detailed information to explain the continuing problems with the wound, what additional measures are being undertaken to address those problems and promote healing and why a switch to alternative treatments alone is not possible.

There are additional requirements necessary for coverage that are not discussed in this article. Please refer to the Negative Pressure Wound Therapy Pumps LCD and related Policy article for complete information.
