S09Other and unspecified injuries of head

Not billable

Is S09 billable?

No — S09 is a non-billable header code. S09 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath S09.

What codes fall under S09? (6)

How long has S09 existed?

S09 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.

Which codes are confused with S09?

ICD-10-CM declares these codes mutually exclusive with S09 — exactly one of each pair can be correct for a given encounter.
