Subdural Hematoma ICD-10 Code: S06.5X0A
Last updated: January 4, 2026
Subdural hematoma (SDH) coding depends on whether it's traumatic or nontraumatic (spontaneous).
Traumatic SDH Codes
| Code | Description |
|---|---|
| S06.5X0A | Traumatic SDH without LOC, initial |
| S06.5X1A | Traumatic SDH with LOC 30 min or less, initial |
| S06.5X2A | Traumatic SDH with LOC 31-59 min, initial |
| S06.5X3A | Traumatic SDH with LOC 1-5:59 hours, initial |
| S06.5X4A | Traumatic SDH with LOC 6-24 hours, initial |
| S06.5X5A | Traumatic SDH with LOC >24h with return to baseline, initial |
| S06.5X6A | Traumatic SDH with LOC >24h without return to baseline, initial |
| S06.5X9A | Traumatic SDH with LOC unspecified duration, initial |
Nontraumatic (Spontaneous) SDH Codes
| Code | Description |
|---|---|
| I62.00 | Nontraumatic subdural hemorrhage, unspecified |
| I62.01 | Nontraumatic acute subdural hemorrhage |
| I62.02 | Nontraumatic subacute subdural hemorrhage |
| I62.03 | Nontraumatic chronic subdural hemorrhage |
7th Character Requirements (Traumatic)
| Character | Meaning |
|---|---|
| A | Initial encounter |
| D | Subsequent encounter |
| S | Sequela |
Coding Tips
- Traumatic vs Nontraumatic: Critical distinction; affects code selection
- LOC duration: Document precisely; affects 6th character
- External cause: Add W/X/Y code for mechanism of injury (traumatic)
- Anticoagulation: Consider I62.0x even with minor trauma if on anticoagulants
Chronic SDH Special Considerations
| Scenario | Code |
|---|---|
| Spontaneous chronic SDH | I62.03 |
| Old traumatic SDH (sequela) | S06.5X_S |
| Chronic SDH from old trauma | S06.5X_D (subsequent) or I62.03 |
External Cause Codes (Traumatic SDH)
| Mechanism | Code Range |
|---|---|
| Fall | W00-W19 |
| Assault | X92-Y09 |
| MVC | V00-V99 |
| Struck by object | W20-W22 |
Frequently Asked Questions
What is the ICD-10 code for subdural hematoma?
S06.5X_A for traumatic SDH (with LOC character), or I62.0x for nontraumatic/spontaneous SDH. The cause determines the code category.
How do I code chronic subdural hematoma?
Use I62.03 (Nontraumatic chronic subdural hemorrhage) for spontaneous chronic SDH. For traumatic, consider S06.5X_D (subsequent) or S06.5X_S (sequela).
What's the difference between S06 and I62 for SDH?
S06.5X is for traumatic subdural hematoma (injury). I62.0x is for nontraumatic/spontaneous subdural hemorrhage (disease). Trauma history determines the code.
