Necrotizing enterocolitis, unspecified

This code represents a severe inflammatory disease of the intestine, primarily affecting premature infants, characterized by intestinal tissue death. It signifies a diagnosis of necrotizing enterocolitis (NEC) where the specific stage or type of NEC is not documented. The condition can lead to perforation, sepsis, and significant morbidity and mortality.

Use this code when the medical record clearly states a diagnosis of necrotizing enterocolitis, but lacks further specification regarding the extent, stage, or specific type (e.g., focal, diffuse). This code is appropriate when the provider's documentation only indicates "necrotizing enterocolitis" without additional detail.

• Do not use this code if more specific documentation regarding the stage or type of NEC is available; instead, use a more precise subcategory.
• Always review the entire medical record for any mention of the stage (e.g., Bell's staging) or specific characteristics of NEC.
• Consider sequencing this code as a principal diagnosis when it is the primary reason for the admission or encounter.
