Summary & Overview
CPT 20527: Collagenase Injection for Dupuytren's Contracture
CPT code 20527 identifies an enzymatic injection procedure used to treat Dupuytren's contracture by injecting an enzyme, such as collagenase, directly into the palmar fascial cord to dissolve the contracted tissue. This procedure offers a less invasive alternative to open fasciectomy and is widely used in outpatient and office settings. Nationally, the code is relevant for procedural coding, coverage determination, and cost analyses related to hand surgery and minimally invasive soft-tissue interventions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for use of the code, payer coverage considerations, and common billing practices tied to outpatient enzymatic treatment for hand contractures. The publication summarizes typical sites of service, expected service type, and common modifiers and ancillary coding considerations where available. It also outlines benchmarking and policy topics readers should expect, including reimbursement patterns, prior authorization trends, and comparative utilization versus surgical alternatives.
This summary is intended for a national audience of coding professionals, clinical managers, and policy analysts seeking concise information on coding, clinical application, and payer engagement for enzymatic treatment of Dupuytren's contracture.
Billing Code Overview
CPT code 20527 describes an injection of an enzyme, such as collagenase, into the palmar fascial cord to dissolve an abnormal tissue knot of the palmar fascia, commonly known as Dupuytren's contracture. This is a therapeutic, minimally invasive procedure intended to enzymatically weaken and rupture the contracted cord.
Service Type: Enzymatic injection for soft-tissue contracture release
Typical Site of Service: Outpatient clinic or physician office
Clinical & Coding Specifications
Clinical Context
A 68-year-old right-hand-dominant male with progressive palmar fascial thickening presents to an outpatient hand clinic with a fixed flexion contracture of the ring and small fingers limiting hygiene and activities of daily living. The diagnosis is Dupuytren's contracture with a palpable palmar cord and contracture at the proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joints. After evaluation by a hand surgeon or hand-specialty advanced practice provider, conservative measures (observation, splinting) were discussed and the decision was made to perform enzymatic fasciotomy using a collagenase injection into the palmar fascial cord.
The typical clinical workflow: referral or clinic evaluation → focused hand exam and documentation of range of motion and functional impairment → informed consent and discussion of risks/benefits → procedural consent and scheduling for office-based injection → administration of CPT 20527 in an ambulatory clinic or outpatient procedure room with local anesthesia as needed → post-injection instructions, scheduling of manipulation if indicated (typically within 24–72 hours), and follow-up for wound care and hand therapy. Typical site of service is an outpatient clinic or ambulatory surgery center. The service type is a therapeutic, office-based or ambulatory procedure for enzymatic dissolution of a palmar fascial cord.

53 | Discontinued procedure | When the procedure is started but terminated for patient-related or unforeseen circumstances before completion. |
23 | Unusual anesthesia | When significant or unusual anesthesia is required beyond local infiltration for patient tolerance. |
22 | Increased procedural services | When the procedure required substantially greater resources or time than typical, with supporting documentation. |
