Peptic ulcer of newborn

This code signifies the presence of an ulceration in the gastrointestinal tract, specifically the stomach or duodenum, occurring in a newborn. This condition results from an imbalance between protective and aggressive factors in the gastric mucosa, leading to tissue erosion.

Apply this code when documentation explicitly states a diagnosis of peptic ulcer in an infant within the neonatal period (birth to 28 days). Supporting clinical findings may include hematemesis, melena, abdominal distension, or evidence of perforation on imaging.

• Ensure the documentation clearly specifies "newborn" or "neonate" to differentiate from peptic ulcers in older infants or children.
• Do not use this code for stress ulcers or gastritis without definitive ulceration.
• Sequence this code as a principal diagnosis if it is the primary reason for admission, or as a secondary diagnosis if it is a co-morbidity affecting care.
