S06.30AA is a billable diagnosis code used to specify a medical diagnosis of unspecified focal traumatic brain injury with loss of consciousness status unknown, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

S06.30AA is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like unspecified focal traumatic brain injury with loss of consciousness status unknown. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

Unspecified diagnosis codes like S06.30AA are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
