About coding cerebral contusion
The ICD-10-CM code for cerebral contusion is S06.33 (Contusion and laceration of cerebrum, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S06.33.
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-).
