    ICD-10-CM Code For Abnormal Findings On Neonatal Screening: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group P09 includes abnormal results from neonatal screening tests, such as metabolic, endocrine, hematologic, and other congenital or inherited conditions detected in the newborn period. These ICD-10-CM diagnosis codes are used to document abnormal screening findings that require confirmatory testing, monitoring, or early intervention, capturing clinical complexity and the need for follow-up. Accurate coding within the ICD-10-CM P09 group supports proper claim adjudication and appropriate reimbursement.

    ICD-10-CM P09: Abnormal Findings On Neonatal Screening Overview

    The ICD-10-CM P09 diagnosis group captures abnormal results identified on newborn screening tests performed shortly after birth. These findings typically relate to metabolic, endocrine, hematologic, or other congenital conditions detected through laboratory or physiologic screening of neonates. Accurate coding supports complete clinical documentation and appropriate reimbursement for follow-up evaluation and management.

    When to Use

    Use a code from this group when a newborn screening test yields an abnormal or positive result that requires follow-up testing, monitoring, or referral. These codes are appropriate for initial encounters documenting the abnormal screen prior to confirmation of a definitive diagnosis.

    Typical Clinical Scenarios

    • A newborn in the well-baby nursery has an abnormal critical congenital heart disease (CCHD) screen with low oxygen saturation on routine pulse oximetry and is referred for cardiology evaluation and echocardiography; the infant is otherwise stable but the abnormal screening result prompts further diagnostic workup, so a code from this group is assigned to capture the abnormal neonatal screen. Typical codes: P09.1.
    • A term neonate fails the newborn metabolic screening with an initial dried blood spot showing an elevated marker suggestive of a metabolic disorder; the baby is admitted for repeat testing, metabolic consult, and temporary dietary management while confirmatory testing is pending, and the abnormal newborn screening result is coded to document the screening finding. Typical codes: P09.2, P09.3.
    • A premature infant in the NICU has an abnormal hearing screen on automated auditory brainstem response (AABR) prior to discharge; the result is documented as abnormal and the infant is scheduled for outpatient diagnostic audiology and follow-up, so an abnormal neonatal screening code is used as a comorbidity on the NICU discharge record. Typical codes: P09.4, P09.8.
