About S06.33
S06.33 is the ICD-10-CM diagnosis code for contusion and laceration of cerebrum, unspecified. It belongs to category S06 (intracranial injury), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 11 subcodes must be used instead.
Within S06.3, choose S06.33 (Contusion and laceration of cerebrum, unspecified) only when documentation doesn't support a more specific option: unspecified focal traumatic brain injury (S06.30), contusion and laceration of right cerebrum (S06.31), contusion and laceration of left cerebrum (S06.32), traumatic hemorrhage of right cerebrum (S06.34), traumatic hemorrhage of left cerebrum (S06.35), traumatic hemorrhage of cerebrum, unspecified (S06.36), contusion, laceration, and hemorrhage of cerebellum (S06.37) and contusion, laceration, and hemorrhage of brainstem (S06.38).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Use an additional code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
