Article Overview

This short coding guidance article focuses on a newborn found to have a possible systolic ejection murmur during a routine physical examination and the need to determine the appropriate ICD-10-CM assignment in the perinatal period. It is relevant to inpatient and outpatient coders, newborn clinicians, and coding educators who work with perinatal diagnoses and neonatal cardiovascular findings.

Why This Topic Matters

Neonatal findings that are not yet fully explained can be coded differently from established diagnoses, so understanding the perinatal classification framework helps support consistent ICD-10-CM reporting.

What You Will Learn

  • How a suspected cardiovascular finding in a newborn is discussed in perinatal coding guidance.
  • Why the perinatal period matters for ICD-10-CM diagnosis selection.
  • How unresolved underlying causes are handled at a high level in this type of coding scenario.
  • The role of ICD-10-CM indexing terms in directing coding review.
