ICD-10-PCS Code For Cerebral Hemisphere: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 00T7 includes procedures performed to resect tissue in the cerebral hemisphere. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of a cerebral hemisphere is surgically removed to treat pathology such as neoplasm, refractory epilepsy, or extensive injury. Accurate coding within the ICD-10-PCS 00T7 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Cerebral Hemisphere Resection Procedure Overview

This procedure group includes resections of all or a portion of a cerebral hemisphere, targeting the central nervous system and cranial nerves. Resection procedures involve cutting out or off brain tissue without replacement to remove pathological tissue, such as tumors or irreversibly damaged brain regions. Accurate ICD-10-PCS coding for these resections is important for precise inpatient documentation and appropriate reimbursement because it captures the extent and anatomical site of the procedure.

When to Use

Use a code from this group when the operative report documents removal of tissue from a cerebral hemisphere as a resection procedure. These codes apply when the procedure removes pathological or nonviable brain tissue and does not include replacement of the removed tissue.

Typical Clinical Scenarios

A 55-year-old patient with a recently diagnosed large, symptomatic glioma confined to one cerebral hemisphere presents for a planned craniotomy because progressively worsening focal neurologic deficits and seizures have failed medical management; inpatient resection of the affected hemisphere tissue is undertaken to remove tumor burden and relieve mass effect. Typical codes: 00T70ZZ.
A 28-year-old with medically refractory focal epilepsy originating from one cerebral hemisphere undergoes an elective hemispherectomy procedure after presurgical evaluation demonstrates unilateral seizure focus and failed multiple antiseizure medications; the goal is resection of the epileptogenic brain tissue to control seizures and improve quality of life. Typical codes: 00T70ZZ.
A 62-year-old who sustained extensive traumatic brain injury with necrotic, nonviable cortical tissue and worsening intracranial hypertension is taken urgently to the operating room for removal of the devitalized cerebral hemisphere tissue to control intracranial pressure and prevent further secondary injury. Typical codes: 00T70ZZ, 00T73ZZ
