P10.0
BillableSubdural hemorrhage due to birth injury
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is P10.0 an HCC code?
Yes. P10.0 maps to Cerebral Hemorrhage under the CMS-HCC V28 risk adjustment model.
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. 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 Cerebral Hemorrhage (HCC 248) with a community, non-dual, aged base RAF weight of 0.289. 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
Excludes 1 — Do NOT code together
- subdural hemorrhage accompanying tentorial tear (P10.4)
Commonly Confused Codes
- •P52.8 — Other specified intracranial non-traumatic hemorrhages of newborn (non-traumatic vs birth injury)
- •P10.1 — Cerebral hemorrhage due to birth injury (cerebral vs subdural location)
- •S06.5X9A — Traumatic subdural hemorrhage without loss of consciousness (non-birth trauma)
- •P91.2 — Neonatal cerebral leukomalacia (white matter injury vs hemorrhage)
