Astrocytoma with Trapped Temporal Horn
A 55-year-old female was admitted with enlarging right temporal horn and right cavity near the lateral ventricle. She had been previously diagnosed with pilocytic astrocytoma and has a long neurosurgical history, status post intraventricular tumor resection, endoscopic membrane lysis, and ventricular peritoneal shunt placement. The patient was admitted for trapped right temporal horn and was also diagnosed with recurrent astrocytoma, hydrocephalus, and encephalopathy. She had re-resection of the tumor. Would it be appropriate to assign a separate diagnosis code for the trapped temporal horn, or is it considered integral to the patient’s condition? ...

Article Overview
This article discusses diagnosis coding for a neurosurgical inpatient case involving recurrent astrocytoma, trapped temporal horn, hydrocephalus, and encephalopathy. It is aimed at coders and CDI staff who need to understand how the case is framed for principal and secondary diagnosis assignment in a brain tumor-related admission.
Why This Topic Matters
Cases involving brain tumors and postoperative or obstructive ventricular findings often raise questions about whether certain diagnoses are reported separately or treated as part of the underlying condition. This article helps readers understand the general coding context for a complex neurosurgical admission without replacing the full premium guidance.
