The code S06.5X9A is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code S06.5X9A might also be used to specify conditions or terms like intracranial hematoma following injury, intracranial hemorrhage following injury with brief loss of consciousness, intracranial hemorrhage following injury with loss of consciousness, intracranial hemorrhage following injury with loss of consciousness, intracranial hemorrhage following injury with open intracranial wound and loss of consciousness , subdural hematoma, etc.

S06.5X9A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like traumatic subdural hemorrhage with loss of consciousness of unspecified duration. 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 S06.5X9A 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.

The code S06.5X9A is linked to some Quality Measures as part of Medicare's Quality Payment Program (QPP).

Information for Patients


Traumatic Brain Injury

Also called: Acquired brain injury, TBI

Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death. Half of all TBIs are from motor vehicle accidents. Military personnel in combat zones are also at risk.

Symptoms of a TBI may not appear until days or weeks following the injury. A concussion is the mildest type. It can cause a headache or neck pain, nausea, ringing in the ears, dizziness, and tiredness. People with a moderate or severe TBI may have those, plus other symptoms:

Health care professionals use a neurological exam and imaging tests to assess TBI. Serious traumatic brain injuries need emergency treatment. Treatment and outcome depend on how severe the injury is. TBI can cause a wide range of changes affecting thinking, sensation, language, or emotions. TBI can be associated with post-traumatic stress disorder. People with severe injuries usually need rehabilitation.
