ICD-10-CM Code C71.7
Malignant neoplasm of brain stem

BILLABLE
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

C71.7 is a billable ICD code used to specify a diagnosis of malignant neoplasm of brain stem. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code C71 is used to code Atypical teratoid rhabdoid tumor

Atypical teratoid rhabdoid tumor (AT/RT) is a rare tumor usually diagnosed in childhood. Although usually a brain tumor, AT/RT can occur anywhere in the central nervous system (CNS) including the spinal cord. About 60% will be in the posterior cranial fossa (particularly the cerebellum). One review estimated 52% posterior fossa, 39% sPNET (supratentorial primitive neuroectodermal tumors), 5% pineal, 2% spinal, and 2% multi-focal.

Malignant neoplasm of brain stem (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 191.7 was previously used, C71.7 is the appropriate modern ICD10 code.
