Summary & Overview
HCPCS S9055: Growth Factor Wound Healing Preparation
HCPCS Level II code S9055 denotes provision of ProcureN or other growth factor preparations used to promote wound healing. These biologic topical agents are increasingly relevant in managing non-healing acute and chronic wounds, pressure injuries, and surgical wound complications. As advanced wound therapies expand, clarity on coding for growth factor preparations matters for clinical documentation, billing consistency, and payer coverage determinations nationally.
Key payers evaluated include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for S9055, how the code is typically used in outpatient wound care and skilled nursing settings, and the common billing considerations tied to application of growth factor products. The publication presents national benchmarks, coding guidance, and policy updates affecting coverage and reimbursement for biologic wound therapies. It also summarizes common modifiers appearing with this service line and highlights documentation elements that tend to influence payer decisions.
This summary is written for clinicians, billing professionals, and policy analysts seeking concise national-level information about coding and policy trends for growth factor wound healing preparations.

Clinical & Coding Specifications
Clinical Context
A 67-year-old patient with a chronic, non-healing lower-extremity ulcer present for 6 months despite standard wound care presents to a wound care clinic. The wound demonstrates poor granulation tissue, minimal epithelialization, and risk factors such as peripheral arterial disease and diabetes mellitus. The facility biller documents use of a topical recombinant growth factor preparation (S9055, Procuren or other growth factor preparation) applied during an outpatient wound care encounter. The clinical workflow includes wound assessment (size, depth, presence of infection), debridement as required, application of the growth factor preparation to the wound bed, dressing placement, patient education on offloading and wound care, and scheduling follow-up visits for reassessment and repeat applications as clinically indicated. Typical sites of service are outpatient wound care clinics, hospital outpatient departments, and skilled nursing facilities where advanced wound therapies are provided. This service is used when wound healing is impaired and adjunctive biological stimulation is indicated after conservative measures have failed.
