About the 0CM Code Range
The root operation Reattachment (code 0CM) in the ICD-10-PCS system refers to reconnecting a body part that was completely detached from its normal location. This procedure is classified under the Medical and Surgical section and specifically targets the Mouth and Throat area.
The ICD-10-PCS Reattachment operation involves restoring anatomical continuity to parts such as the Upper Lip (code 0CM00ZZ), Lower Lip (code 0CM10ZZ), Soft Palate, Tongue, and Uvula. It also includes the reattachment of dental structures, covering both Upper and Lower Teeth in single, multiple, or all teeth categories, with approaches ranging from Open (e.g., 0CMW0Z0) to External (e.g., 0CMWXZ0). These detailed codes allow precise documentation of reattachment procedures, essential for accurate clinical records and billing when addressing traumatic injuries or surgical reconstructions of the mouth and throat region.
