Massive pulmonary hemorrhage origin in the perinatal period

This code signifies a severe, extensive bleeding event within the lungs of a newborn, occurring shortly before, during, or immediately after birth. This condition is life-threatening and involves significant blood loss into the pulmonary tree, often leading to respiratory distress and failure.

Assign this code for neonates diagnosed with substantial intrapulmonary bleeding that is clearly documented as originating within the perinatal period. Documentation should specify the massive nature of the hemorrhage and its onset relative to birth. This code is appropriate when the hemorrhage is the primary diagnosis or a significant co-morbidity impacting the newborn's care.

• Ensure documentation explicitly states "massive" or a similar descriptor indicating severe hemorrhage, and confirms perinatal origin.
• Distinguish from less severe pulmonary hemorrhages (P26.0, P26.8, P26.9) which do not meet the "massive" criteria.
• Consider sequencing with codes for underlying causes or associated conditions, such as prematurity or respiratory distress syndrome.
