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 00B7 includes procedures performed to excise tissue or portions of the cerebral hemisphere. These ICD-10-PCS codes are used for inpatient documentation when a portion of the cerebral hemisphere is surgically removed for conditions such as tumors, infarction, hemorrhage, or other focal pathology. Accurate coding within the ICD-10-PCS 00B7 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Cerebral Hemisphere Excision Procedure Overview

Procedures in this group involve the excision of tissue from the cerebral hemisphere and target the central nervous system and cranial nerves. These operations remove a portion of the cerebral hemisphere for diagnostic or therapeutic reasons, such as tumor resection or removal of necrotic tissue. Accurate coding of these excisions is important for inpatient reimbursement because it documents the extent and intent of the surgical intervention and supports appropriate case mix classification.

Typical Clinical Scenarios

An adult patient presents to the emergency department with acute worsening of neurologic status after a large ischemic stroke with malignant cerebral edema causing midline shift and declining consciousness; neurosurgeons perform an open craniectomy with excision of infarcted cerebral hemisphere tissue to decompress the brain and remove necrotic tissue. A code from this excision group is used to report removal of cerebral hemisphere tissue performed via an open approach in the inpatient setting. Typical codes: 00B70ZX, 00B70ZZ
A middle-aged patient with a newly diagnosed, symptomatic cortical glioma undergoes a planned, image-guided percutaneous endoscopic resection to remove the tumor-bearing portion of the cerebral hemisphere for therapeutic intent and tissue diagnosis; the patient is admitted postoperatively for monitoring and further oncologic planning. Use a percutaneous endoscopic excision code to reflect removal of cerebral hemisphere tissue through an endoscopic minimally invasive approach. Typical codes: 00B74ZX, 00B74ZZ
A patient with recurrent seizure disorder due to a localized cortical malformation previously treated conservatively is admitted for a staged percutaneous excisional procedure to remove the epileptogenic focus in the cerebral hemisphere after prior interventions failed; the procedure targets removal of dysfunctional cortical tissue to control seizures and is performed using a percutaneous approach. Typical codes: 00B73ZX, 00B73ZZ
