Summary & Overview
HCPCS Q4247: Amniotext Patch, Per Square Centimeter (Add-on)
HCPCS Level II code Q4247 identifies an amniotext patch billed per square centimeter as an add-on service in addition to a primary procedure. This code captures the use of an implantable biologic patch intended to support fetal membranes or adjacent tissues during surgical repair or intervention. Nationally, accurate reporting of add-on device and biologic codes like Q4247 matters for clinical documentation, claims processing, and product utilization tracking.
Key payers in the national landscape include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, typical sites of service (operating room or procedural suite, inpatient or outpatient), and the billing characteristics associated with add-on, per-unit reporting. The publication outlines common modifiers and administrative considerations where available, and highlights areas where payer policy alignment affects coverage and coding practice.
The report is designed to help coding professionals, revenue cycle teams, and policy analysts understand how Q4247 is reported and interpreted across major payers, what documentation supports appropriate use, and what benchmarks and policy updates to monitor. Data not available in the input is noted where applicable.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient wound care clinic or operating room with a nonhealing surgical wound, chronic diabetic foot ulcer, venous stasis ulcer, or complex soft-tissue defect requiring biologic wound matrix augmentation. The clinician selects Q4247 (amniotext patch, per square centimeter) as an add-on product applied to the wound bed after appropriate debridement and hemostasis. Typical workflow: the patient is evaluated and wound measurements recorded; sharp or surgical debridement is performed under local or monitored anesthesia; hemostasis and irrigation are achieved; the clinician sizes the amniotic patch to fit the prepared wound and secures it with sutures, adhesive, or an overlying dressing; documentation includes wound dimensions, area of product used (square centimeters), indication, and method of application. The service commonly occurs in an outpatient wound clinic, ambulatory surgery center, or inpatient operating room when performed with a primary surgical procedure. Payer billing uses Q4247 as an add-on supply code in addition to the primary procedure code, with appropriate modifiers to reflect unusual circumstances or reduced/abandoned services.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | When work, time, or intensity substantially exceeds usual for the primary procedure and separate documentation supports additional effort associated with applying the patch |
