Traumatic Brain Injury
Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull. This is a penetrating injury.

Questions About S06.330SOverview
Is S06.330S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report contusion and laceration of cerebrum, unspecified, without loss of consciousness, sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in S06.330S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the contusion and laceration of cerebrum, unspecified, without loss of consciousness itself has resolved, not the original event.
Is S06.330S 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 contusion and laceration of cerebrum, unspecified, without loss of consciousness, sequela on inpatient claims.
What is the ICD-9 equivalent of S06.330S?
Under the General Equivalence Mappings, contusion and laceration of cerebrum, unspecified, without loss of consciousness, sequela converts to ICD-9-CM 907.0 (lt eff intracranial inj). The mapping is approximate, so confirm the match fits the documentation.
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.
