P52.8 is a billable ICD-10-CM diagnosis code for other intracranial (nontraumatic) hemorrhages of newborn. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 791, 793. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 39 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Hemorrhagic and hematologic disorders of newborn.
For Medicare Advantage risk adjustment, P52.8 maps to CMS-HCC Category 248 (Intracranial Hemorrhage) under the V28 model, adding a risk factor of about 0.239 for a community, non-dual, aged beneficiary in payment year 2026.
