I62.0Nontraumatic subdural hemorrhage

I62.0 is the ICD-10-CM diagnosis code for nontraumatic subdural hemorrhage. It belongs to category I62 (other and unspecified nontraumatic intracranial hemorrhage), block I60-I69 (cerebrovascular diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within I62 (other and unspecified nontraumatic intracranial hemorrhage), I62.0 is specifically for nontraumatic subdural hemorrhage. Related codes cover extradural hemorrhage (I62.1) and intracranial hemorrhage, unspecified (I62.9).

To report this condition, pick the subcode that matches the documentation: I62.00 (unspecified), I62.01 (hemorrhage), I62.02 (hemorrhage) and I62.03 (hemorrhage).

Use an additional code, if known, to indicate National Institutes of Health Stroke Scale (NIHSS) score (R29.7-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
