What is ICD-10 code P10.0?

P10.0 is the ICD-10-CM diagnosis code for Subdural hemorrhage due to birth injury. Bleeding between the brain and its outer membrane (subdural space) that occurred as a result of trauma during the birth process. P10.0 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. P10.0 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. P10.0 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. P10.0 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

What is the V28 vs V24 difference for P10.0?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. P10.0 is a payment HCC under V28 (Intracranial Hemorrhage) but was not retained as a payment HCC under V24. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting P10.0?

Document the severity and location of the subdural hemorrhage; specify whether it is acute, subacute, or chronic if applicable Link to delivery complications and maternal factors that may have contributed to the birth injury Because P10.0 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Is P10.0 an HCC code?

Yes. P10.0 (Subdural hemorrhage due to birth injury) maps to Intracranial Hemorrhage under the CMS-HCC V28 risk adjustment model, with a community non-dual aged RAF of 0.239. It is billable for payment year 2026.

Coder answer: P10.0 is billable and maps to V28 HCC 248, Intracranial Hemorrhage. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

HCC Category Mapping

V28HCC 248, Intracranial Hemorrhage

0.239

Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for P10.0

For P10.0 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed P10.0 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

P10.0 is the ICD-10-CM diagnosis code for subdural hemorrhage due to birth injury. Bleeding between the brain and its outer membrane (subdural space) that occurred as a result of trauma during the birth process. P10.0 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering birth trauma (p10-p15).

Under the CMS-HCC V28 risk adjustment model, P10.0 maps to Intracranial Hemorrhage (HCC 248) with a community, non-dual, aged base RAF weight of 0.239. P10.0 was not retained as a payment HCC under the older V24 model, so V28 introduced or recategorized it during the 2024–2026 phase-in. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.

Document the severity and location of the subdural hemorrhage; specify whether it is acute, subacute, or chronic if applicable. Because P10.0 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P10.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document the severity and location of the subdural hemorrhage; specify whether it is acute, subacute, or chronic if applicable
•Link to delivery complications and maternal factors that may have contributed to the birth injury

Clinical Significance

Subdural hemorrhage due to birth injury represents serious intracranial bleeding that can cause immediate neurological complications and long-term developmental disabilities. These newborns require intensive monitoring for increased intracranial pressure and may need neurosurgical intervention.

Documentation Requirements

✓Documentation of subdural hemorrhage confirmed by imaging
✓Evidence that hemorrhage resulted from birth trauma
✓Description of delivery complications or instrumentation
✓Clinical signs of intracranial bleeding
✓Neurological assessment findings
✓Neurosurgical consultation if indicated
✓Serial imaging studies and monitoring plan
