S06.5X9S is a billable diagnosis code used to specify a medical diagnosis of traumatic subdural hemorrhage with loss of consciousness of unspecified duration, sequela. The code S06.5X9S 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 S06.5X9S 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 , late effect of complications of trauma, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

S06.5X9S is a sequela code, includes a 7th character and should be used for complications that arise as a direct result of a condition like traumatic subdural hemorrhage 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 S06.5X9S 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.

Information for Patients


Bleeding Disorders

Also called: Clotting disorders

Normally, if you get hurt, your body forms a blood clot to stop the bleeding. For blood to clot, your body needs cells called platelets and proteins known as clotting factors. If you have a bleeding disorder, you either do not have enough platelets or clotting factors or they don't work the way they should.

Bleeding disorders can be the result of other diseases, such as severe liver disease or a lack of vitamin K. They can also be inherited. Hemophilia is an inherited bleeding disorder. Bleeding disorders can also be a side effect of medicines such as blood thinners.

Various blood tests can check for a bleeding disorder. You will also have a physical exam and history. Treatments depend on the cause. They may include medicines and transfusions of blood, platelets, or clotting factor.
