0CU is a non-billable ICD-10-PCS code that heads the group for Mouth and Throat, Supplement, so it cannot be submitted on a claim; a more specific seven-character code is required. The root operation Supplement involves putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.
