AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Issue 4; New/Revised ICD-10-CM Codes
Neonatal Cerebral Infarction
A new subcategory P91.82, Neonatal cerebral infarction, has been created with the following codes to describe right, left, bilateral and unspecified neonatal cerebral infarction:P91.821 Neonatal cerebral infarction, right side of brain P91.822 Neonatal cerebral infarction, left side of brain P91.823 Neonatal cerebral infarction, bilateral P91.829 Neonatal cerebral infarction, unspecified side Neonatal cerebral infarction (or stroke) is a cerebrovascular condition that occurs between 20 weeks of fetal life through the 28th postnatal day. This condition is defined as a severe disorganization or even a complete disruption of the gray matter of the developing brain caused...

Article Overview
This premium article covers the addition of a new ICD-10-CM subcategory for neonatal cerebral infarction and provides clinical background on how the condition is recognized, described, and documented in newborns. It is aimed at coders, CDI staff, billers, and neonatal clinicians who need to understand the scope of the diagnosis and the related documentation considerations. The article also includes a coding-oriented admission example illustrating how the diagnosis is reflected in newborn inpatient coding.
Why This Topic Matters
Neonatal neurologic diagnoses can affect coding accuracy, record specificity, and downstream reporting. Understanding the updated diagnosis category and the clinical features that support documentation helps users identify relevant records and code the encounter appropriately.
