Transient neonatal neutropenia

This code describes a temporary decrease in neutrophils, a type of white blood cell, in a newborn infant. This condition is typically benign and resolves spontaneously within the first few weeks or months of life. It is distinct from more severe or chronic forms of neutropenia.

Use this code for newborns diagnosed with a transient, self-limiting reduction in neutrophil count. Documentation should clearly indicate the neonatal period and the temporary nature of the neutropenia, often without an identifiable underlying cause or requiring specific treatment.

• Ensure documentation specifies "transient" or "neonatal" to differentiate from other neutropenia types.
• Do not code this with congenital neutropenia (D70.0) as per the Excludes1 note.
• Review the medical record for any associated conditions or underlying causes that might require additional coding.
