S06.4X9A — Epidural hemorrhage with loss of consciousness of unspecified duration, initial encounter
Is S06.4X9A billable?
Yes, but S06.4X9A is an unspecified code. S06.4X9A is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, S06.4X9A is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting S06.4X9A — the more specific alternatives are listed below.

Which MS-DRGs does S06.4X9A group to?
S06.4X9A sits in MDC 01 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Excludes1 — never code together — inherited from S06
The conditions below can never be reported together with S06.4X9A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- head injury NOS (S09.90)
Use additional code — inherited from Chapter 19
Report an additional code alongside S06.4X9A to fully describe the condition. S06.4X9A is sequenced first.

How long has S06.4X9A existed?
S06.4X9A has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
