What does the 7th character S in S06.9X6S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the unspecified intracranial injury with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving itself has resolved, not the original event.

Is S06.9X6S exempt from POA reporting?

CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for unspecified intracranial injury with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving, sequela on inpatient claims.

What is the ICD-9 equivalent of S06.9X6S?

Under the General Equivalence Mappings, unspecified intracranial injury with loss of consciousness greater than 24 hours without return to pre-existing conscious level with patient surviving, sequela converts to ICD-9-CM 907.0 (lt eff intracranial inj).
