Summary & Overview
HCPCS A6246: Hydrogel Wound Dressing, 16–48 sq. in.
HCPCS Level II code A6246 represents a sterile hydrogel wound dressing sized greater than 16 sq. in. and up to 48 sq. in., billed per dressing. These dressings are widely used across outpatient clinics, wound care centers, and home health settings for management of partial- and full-thickness wounds, burns, and other wounds requiring moisture-retentive coverage. Nationally, supply codes for advanced dressings matter because they affect outpatient and durable medical equipment payments, influence wound-care protocol costs, and intersect with payer coverage policies that vary by plan.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coding purpose and clinical context, typical sites of service, common modifiers used with supply codes, and what is available regarding payer coverage patterns and billing practice considerations. The publication also outlines benchmarks where available and notes any recent policy updates affecting hydrogel and advanced wound dressing reimbursement.
Where specific data elements were not provided in the input, the report states "Data not available in the input." The content is intended for clinicians, billing staff, and policy analysts seeking a concise reference on HCPCS Level II code A6246 and its role in wound-care supply billing.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a partial- or full-thickness wound such as a diabetic foot ulcer, venous stasis ulcer, pressure injury, or superficial traumatic wound requiring moist wound healing. In an outpatient wound clinic, home health visit, emergency department, or inpatient bedside dressing change, the clinician assesses the wound, performs wound cleansing and debridement as indicated, measures wound dimensions to confirm dressing size, selects an appropriate sterile hydrogel dressing, and applies A6246 (hydrogel dressing, pad size >16 sq. in. and ≤48 sq. in.). The workflow includes documentation of wound characteristics (location, size, depth, exudate, signs of infection), rationale for hydrogel use (re-hydration of dry wound bed, autolytic debridement, pain reduction), lot numbers and sterile technique, patient tolerance, and instructions for follow-up dressing changes. Typical sites of service include outpatient wound centers, home health visits, hospital bedside, urgent care, and long-term care facilities. Common patient factors include peripheral neuropathy, impaired circulation, immobility, or recent surgical incision complications requiring a large sterile hydrogel pad for wound bed moisture management.
