CPT® Code 25136

The procedure described by CPT® Code 25136 involves the excision or curettage of a bone cyst or a benign tumor located within the carpal bones, which are the eight small bones that form the wrist joint. This surgical intervention is performed to remove non-cancerous growths that may cause discomfort, limit mobility, or lead to other complications. The term 'excision' refers to the surgical removal of tissue, while 'curettage' involves scraping away the abnormal tissue. In this specific procedure, the wound created by the removal of the cyst or tumor is repaired using an allograft, which is a bone graft sourced from a donor patient rather than the patient's own body. This distinction is crucial for coding purposes, as it differentiates between the use of an allograft and an autograft, the latter being coded under CPT® Code 25135. Understanding the nuances of these procedures is essential for accurate medical coding and billing, ensuring that healthcare providers are appropriately reimbursed for the services rendered.
