Other disturbances of cerebral status of newborn (P91) ICD-10-CM
The P91 code range covers other disturbances of cerebral status of newborn with 23 ICD-10-CM diagnosis codes. 18 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the P91 range.
Ischemic Stroke
Stroke due to BRAIN ISCHEMIA resulting in interruption or reduction of blood flow to a part of the brain. When obstruction is due to a BLOOD CLOT formed within in a cerebral blood vessel it is a thrombotic stroke. When obstruction is formed elsewhere and moved to block a cerebral blood vessel (see CEREBRAL EMBOLISM) it is referred to as embolic stroke. Wake-up stroke refers to ischemic stroke occurring during sleep while cryptogenic stroke refers to ischemic stroke of unknown origin.
About the P91 Code Range
The ICD-10 code section P91 is used to classify a variety of specific disturbances affecting the cerebral status of newborns. These codes address conditions ranging from neonatal cerebral ischemia and hypoxic ischemic encephalopathy (HIE) to neonatal cerebral infarction and different types of neonatal encephalopathy.
This section covers unique conditions such as neonatal cerebral ischemia (P91.0), known also as acute cerebral ischemia or epilepsy due to perinatal cerebral ischemia, highlighting brain blood flow issues in newborns. Codes like P91.6 for hypoxic ischemic encephalopathy (HIE) further specify severity levels, including mild, moderate, or severe forms, which reflect the extent of oxygen deprivation to the newborn's brain. Other codes, like P91.82 for neonatal cerebral infarction, distinguish the affected brain side, aiding in precise documentation. Additional listings cover acquired cysts, cerebral irritability or depression, coma, and unspecified neonatal encephalopathies with related synonyms to clarify coding choices. These specific codes are essential for accurately identifying and documenting various cerebral conditions in neonates, thereby guiding appropriate clinical care and billing.
