ICD-10-PCS Code for Temporal Bone, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0NU6 includes procedures performed to supplement bone or related structures in the left temporal bone. These ICD-10-PCS codes are used for inpatient documentation when biological or synthetic material is placed to reinforce or augment the left temporal bone. Accurate coding within the ICD-10-PCS 0NU6 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Temporal Bone, Left Supplement Procedure Overview

Procedures in this group involve placement of biological or synthetic material to reinforce or augment the structure or function of the left temporal bone, which is part of the head and facial bones body system. These interventions typically supplement existing bone or related structures to restore stability, support, or hearing-related function. Accurate ICD-10-PCS coding of these procedures ensures inpatient records reflect the specific supplement performed and supports correct reimbursement and case mix assignment.

Typical Clinical Scenarios

A 45-year-old patient presents after a high-energy lateral skull fracture from a motor vehicle collision causing comminution of the left temporal bone with instability and cosmetic deformity; the patient is taken to the operating room for open reconstruction where biologic graft or synthetic plate is secured to reinforce the fractured temporal bone and restore contour and protection of intracranial contents. Typical codes: 0NU607Z, 0NU60JZ
An elderly patient with chronic otologic disease and progressive conductive hearing loss has planned elective mastoid and tympanomastoid reconstruction where bone graft or alloplastic material is applied percutaneously endoscopically to augment the left temporal bone and improve ossicular support and middle ear architecture; the patient is admitted for the scheduled inpatient procedure due to comorbidities and anticipated observation. Typical codes: 0NU647Z, 0NU64JZ
A patient with prior temporal bone tumor resection develops a postoperative bony defect with cerebrospinal fluid leak and recurrent infections; during a revision percutaneous procedure the surgeon places nonautologous tissue substitute material to supplement and seal the left temporal bone defect and prevent further intracranial communication. Typical codes: 0NU63KZ, 0NU60KZ
