SDH ICD-10-CM Codes

What ICD-10 codes are used for SDH?

A subdural hematoma occurs when blood collects abnormally beneath the dura mater—the tough outer membrane that protects the brain and spinal cord and lies just beneath the skull.

Here's a list of the ICD-10 codes for subdural hematoma (SDH) that practitioners can use for billing, coding, documentation, etc.:

Traumatic subdural hematoma

• S06.5X0A - Traumatic subdural hemorrhage without loss of consciousness, initial encounter
• S06.5X1A - Traumatic subdural hemorrhage with loss of consciousness of 30 minutes or less, initial encounter
• S06.5X2A - Traumatic subdural hemorrhage with loss of consciousness of 31 minutes to 59 minutes, initial encounter
• S06.5X3A - Traumatic subdural hemorrhage with loss of consciousness of 1 hour to 5 hours 59 minutes, initial encounter
• S06.5X4A - Traumatic subdural hemorrhage with loss of consciousness of 6 hours to 24 hours, initial encounter
• S06.5X5A - Traumatic subdural hemorrhage with loss of consciousness greater than 24 hours with return to pre-existing conscious level, initial encounter
• S06.5X6A - Traumatic subdural hemorrhage with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving, initial encounter
• S06.5X7A - Traumatic subdural hemorrhage with loss of consciousness of any duration with death due to brain injury before regaining consciousness, initial encounter
• S06.5X8A - Traumatic subdural hemorrhage with loss of consciousness of any duration with death due to other cause before regaining consciousness, initial encounter
• S06.5X9A - Traumatic subdural hemorrhage with loss of consciousness of unspecified duration, initial encounter
• S06.5XAA - Traumatic subdural hemorrhage with loss of consciousness status unknown, initial encounter

Non-traumatic subdural hematoma

• I62.01 - Nontraumatic acute subdural hemorrhage
• I62.02 - Nontraumatic subacute subdural hemorrhage
• I62.03 - Nontraumatic chronic subdural hemorrhage
• I62.00 - Nontraumatic subdural hemorrhage, unspecified

For the traumatic subdural hematoma codes, please note that all of those are for initial encounters. For subsequent encounters, replace the last letter with a D. For sequela, replace the letter with an S.

Clinical information

• When blood collects on one's brain's surface due to a tear in the vein or clot, it's called a subdural hematoma or SDH. 
• There are two types of subdural hematomas: acute and chronic. Acute subdural hematomas are because of severe head injuries like car accidents, blows to the head, etc., and it's the most dangerous type of SDH. On the other hand, chronic subdural hematomas are because of minor head injuries and symptoms aren't immediately noticeable.
• Whether acute or chronic, the common symptoms of a subdural hematoma are numbness, drowsiness, weakness, confusion, nausea, slurred speech, loss of consciousness/function on one side, and severe headaches. 
• A patient will undergo imaging tests like a CT or MRI scan to diagnose SDH. 
• Treatments for SDH include a craniotomy, burr hole, and medication.

Synonyms include

• Subdural hematoma, traumatic
• Subdural hemorrhage, after injury
• Traumatic subdural hematoma
• Nontraumatic subdural hematoma
• Subdural hematoma with coma or brain compression
• Subdural hematoma due to traumatic brain compression
• Subdural hemorrhage with loss of consciousness
