Questions About S06.36ASOverview

Is S06.36AS a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report traumatic hemorrhage of cerebrum, unspecified, with loss of consciousness status unknown, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What does the 7th character S in S06.36AS mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the traumatic hemorrhage of cerebrum, unspecified, with loss of consciousness status unknown itself has resolved, not the original event.

Is S06.36AS exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for traumatic hemorrhage of cerebrum, unspecified, with loss of consciousness status unknown, sequela on inpatient claims.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
