About S06.5
S06.5 is the ICD-10-CM diagnosis code for traumatic subdural hemorrhage. It belongs to category S06 (intracranial injury), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 1 subcodes must be used instead.
Within S06 (intracranial injury), S06.5 is specifically for traumatic subdural hemorrhage. Related codes cover concussion (S06.0), traumatic cerebral edema (S06.1), diffuse traumatic brain injury (S06.2), focal traumatic brain injury (S06.3), epidural hemorrhage (S06.4), traumatic subarachnoid hemorrhage (S06.6), other specified intracranial injuries (S06.8), unspecified intracranial injury (S06.9) and 1 more.
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Use an additional code, if applicable, for traumatic brain compression or herniation (S06.A-). Use an additional code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
