Cardiovasc disorder origin in the perinatal period, unsp

This code signifies a cardiovascular abnormality or dysfunction identified in a neonate or infant, where the precise nature of the heart condition is not specified. It indicates a problem with the heart or blood vessels that originated during the perinatal period (from the 28th week of gestation through 28 days after birth).

Utilize this code when documentation clearly states a cardiovascular disorder of perinatal origin but lacks specific details regarding the type of defect (e.g., "perinatal cardiac anomaly, type unspecified" or "neonatal heart murmur, etiology undetermined"). This is appropriate when further diagnostic workup is pending or inconclusive.

• Avoid using this code if a more specific cardiovascular diagnosis (e.g., congenital heart defect, arrhythmia) is documented.
• Always review the entire medical record for additional details that might allow for a more precise code selection.
• Consider sequencing this code after a code for the primary reason for admission or encounter, if applicable.
