About the 0CU Code Range

The ICD-10-PCS root operation Supplement (code 0CU) refers to the procedural addition of material to a body part to reinforce or support the structure. This operation is categorized in the Medical and Surgical section and specifically targets the Mouth and Throat body region.

The provided codes exemplify how Supplement procedures involve using different types of tissue substitutes—such as autologous (the patient's own tissue), synthetic, or nonautologous substitutes—to enhance various anatomical parts of the mouth and throat. This includes areas like the Upper and Lower Lip, Hard and Soft Palate, Buccal Mucosa, Gingiva, Tongue, Pharynx, Uvula, Epiglottis, Larynx, and Vocal Cords. The approach may be Open, Percutaneous, External, or via Natural or Artificial Openings, including endoscopic methods, reflecting procedural diversity in how supplementation is performed. For example, code 0CU007Z describes supplementing the upper lip with autologous tissue using an open approach, while 0CUM77Z covers supplementing the pharynx via a natural opening.
