About the 0C0 Code Range
The ICD-10-PCS root operation Alteration (character 0C0) involves modifying the appearance of the mouth and throat without affecting their basic structure or function. This procedure is often performed to improve cosmetic appearance or restore a more typical look.
Within the Medical and Surgical section, the Alteration operation can be applied to specific body parts like the Upper Lip and Lower Lip using various tissue substitutes and approaches.
