ICD-10 Code I62.0: Nontraumatic subdural hemorrhage
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Diseases of the circulatory system (I00-I99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes nontraumatic subdural, extradural, or otherwise unspecified intracranial hemorrhage in the I62 family. The most accurate code depends on whether the bleed is subdural versus extradural and, for subdural hemorrhage, whether the phase is unspecified, acute, subacute, or chronic.
When is it used?
- May be used when a clinician documents nontraumatic subdural hemorrhage in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Emergency, inpatient, neurology, neurosurgery, and utilization-review workflows where nontraumatic intracranial bleeding is part of the active assessment.
- Coding workflows where the chart identifies subdural versus extradural location, subdural phase, or whether the bleed remains otherwise unspecified.
Common management context
- Evaluation often includes brain imaging review, neurologic examination, hemodynamic and anticoagulation context, and coordination across neurology, neurosurgery, and critical-care teams.
- Documentation usually becomes more specific when the chart identifies subdural versus extradural bleeding and clarifies unspecified versus acute versus subacute versus chronic subdural pattern.
- Specialist context already linked on this page includes Cardiologist, General Physician, Orthopedic Specialist.
🔍Key distinctions
Important notes
- This ICD-10 family captures nontraumatic subdural, extradural, and otherwise unspecified intracranial hemorrhage rather than subarachnoid or intracerebral hemorrhage.
- Hemorrhage location and, for subdural bleeding, temporal phase are what drive final code specificity inside this family.
- This title groups nontraumatic subdural hemorrhage patterns, and the final code usually depends on whether the bleed is unspecified, acute, subacute, or chronic.
- Documentation that describes this nontraumatic intracranial hemorrhage branch is coded differently from subarachnoid hemorrhage, intracerebral hemorrhage, traumatic intracranial bleeding, or cerebral infarction.
