P52
Non-Billable (Header)Intracranial nontraumatic hemorrhage of newborn
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
What This Code Means
P52 is the ICD-10-CM diagnosis code for intracranial nontraumatic hemorrhage of newborn. P52 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering hemorrhagic and hematological disorders of newborn (p50-p61).
Header codes like P52 cannot be reported on claims directly — they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at P52's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P52 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
