CPT® Code 20200

An incisional biopsy of muscle tissue, designated by CPT® Code 20200, involves the surgical removal of a small sample from the superficial layer of muscle. This procedure is primarily utilized for diagnostic purposes, allowing healthcare providers to investigate various muscle-related diseases. Conditions such as muscular dystrophy, myasthenia gravis, polymyositis, dermatomyositis, amyotrophic lateral sclerosis (ALS), Friedreich's ataxia, and parasitic infections like trichinosis or toxoplasmosis can be evaluated through this biopsy. The process begins with the careful cleansing of the intended biopsy site to minimize the risk of infection. Following this, a precise incision is made in the muscle to extract a tissue sample, which is then sent for pathology examination to determine the presence of any underlying conditions. It is important to note that CPT® Code 20200 is specifically used for biopsies involving a superficial incision, while CPT® Code 20205 is reserved for deeper muscle biopsies that require more extensive tissue dissection.
