Which ICD-10-CM code best describes a newborn with melena due to swallowed maternal blood at birth?

• A. P78.0
• B. P78.2
• C. P79.0
• D. P78.3

Answer: (B)

In ICD-10-CM coding for newborns, certain codes are designed to capture conditions that originate specifically in the perinatal period and, when possible, tie the presentation to its birth-related cause. A newborn who has melena because they swallowed maternal blood at birth is a distinct perinatal scenario, and there is a code that precisely describes this combination of symptom and etiology. The option that names melena in the newborn due to swallowed maternal blood provides the most exact description of the case, making it the best choice. The other options refer to different neonatal conditions or presentations that do not specify the exact cause of the melena, so they don’t fit as well.
