Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the P91 range.

Hypoxic Ischemic Encephalopathy

Ischemic brain damage in which the entire brain is deprived of oxygen. It may be fatal or lead to long term disabilities including developmental delays, intellectual disability, and seizures.

Neonatal Encephalopathy

Abnormal functioning of the central nervous system in the newborn period that may be due to a variety of etiologies including hypoxia/ischemia, metabolic disturbance, or infection.

About the P91 Code Range

These newborn conditions affect the brain. P91 separates named disturbances, including acquired cysts, irritability, depression, and coma, from other specified and unspecified disturbances.

Hypoxic ischemic encephalopathy (HIE) has codes for unspecified, mild, moderate, and severe forms under P91.6. Under other specified disturbances, P91.81 separates newborn encephalopathy in diseases classified elsewhere from unspecified newborn encephalopathy. P91.82 separates newborn brain infarction by right, left, both, or unspecified sides of the brain.
