HCPCS K0745: Absorptive Wound Dressing for Portable Home Suction Pump

HCPCS Level II code K0745 identifies an absorptive wound dressing designed for use with a portable home suction pump, with pad size greater than 16 square inches up to 48 square inches. The code is used in billing for negative pressure wound therapy (NPWT) supplies provided in the home or other outpatient settings where a portable suction device is employed. Nationally, K0745 matters because NPWT supplies represent a recurring, clinically important category of durable medical equipment that affects patient access to home-based wound care and influences durable medical equipment spending trends.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context for portable NPWT dressings, typical sites of service, and which payers commonly adjudicate claims for these items. The publication also outlines available benchmarks and policy considerations relevant to coverage and billing for home-based suction pump dressings, and highlights areas where payers may differ in coverage criteria or documentation requirements.

This summary equips clinicians, billing professionals, and policy analysts with the essential background on K0745, the payer landscape covered in the review, and what to expect in the full publication regarding reimbursement benchmarks, policy updates, and clinical usage for portable home NPWT dressings.

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with a chronic, non-healing lower-extremity wound following venous stasis and prior debridement is discharged home with a portable negative pressure wound therapy (NPWT) system. The clinician supplies an absorptive wound dressing pad sized greater than 16 square inches but not exceeding 48 square inches, intended for use with the home-model suction pump to manage exudate, promote granulation, and reduce dressing change frequency. Home health nursing reviews device operation, dressing application, skin assessment, and schedules follow-up with the wound care clinic. Supplies are billed using K0745 for the absorptive pad; clinical documentation includes wound measurements, exudate amount, device model, and training provided to the patient or caregiver.

`L97.522`	Non-pressure chronic ulcer of left ankle with necrosis of bone	Deep, non-healing ulcers with extensive drainage may require home NPWT pads sized within the `K0745` specification.
`I83.019`	Varicose veins of lower extremity with ulcer, unspecified leg	Venous stasis ulcers commonly managed with NPWT to control exudate and promote healing after debridement.
`E11.621`	Type 2 diabetes mellitus with foot ulcer	Diabetic foot ulcers frequently produce moderate to heavy exudate and are appropriate indications for absorptive NPWT dressings.
`L89.154`	Pressure ulcer of sacral region, stage 4	Large, deep pressure injuries healed with NPWT in the home setting may use dressings sized within the `K0745` range.
