S06.9X9S is a billable diagnosis code used to specify a medical diagnosis of unspecified intracranial injury with loss of consciousness of unspecified duration, sequela. The code S06.9X9S is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code S06.9X9S might also be used to specify conditions or terms like brain injury with open intracranial wound and loss of consciousness, brain injury without open intracranial wound and with loss of consciousness, closed fracture of base of skull, closed fracture of base of skull with intracranial injury, closed fracture of base of skull with loss of consciousness , closed fracture of vault of skull, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

S06.9X9S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like unspecified intracranial injury with loss of consciousness of unspecified duration. According to ICD-10-CM Guidelines a "sequela" code should be used for chronic or residual conditions that are complications of an initial acute disease, illness or injury. The most common sequela is pain. Usually, two diagnosis codes are needed when reporting sequela. The first code describes the nature of the sequela while the second code describes the sequela or late effect.

Unspecified diagnosis codes like S06.9X9S 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.
