🔎 What is CPT Code 97602?
97602 is defined as:
“Removal of devitalized tissue from wound(s), non-selective debridement, without anesthesia (e.g., wet-to-moist dressings, enzymatic, abrasion), including topical application(s), wound assessment, and instruction(s) for ongoing care, per session.”
Let’s simplify it.
CPT 97602 represents non-selective wound debridement, which removes both healthy and dead tissue without anesthesia. Unlike selective methods, this approach uses mechanical, enzymatic, or abrasive techniques and is often applied when the distinction between viable and non-viable tissue isn’t possible.
It’s often dubbed the “Sometimes Therapy Code” because it may or may not require a therapy plan of care depending on the provider.
