The ICD-10-CM code S09.90XD might also be used to specify conditions or terms like closed injury of head, closed wound of head, conversion muteness, friction alopecia, head and neck injury , headache due to injury of head and neck, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
S09.90XD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like unspecified injury of head. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.
Unspecified diagnosis codes like S09.90XD 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
Also called: Cranial injuries, Skull fractures, Skull injuries
Chances are you've bumped your head before. Often, the injury is minor because your skull is hard and it protects your brain. But other head injuries can be more severe, such as a skull fracture, concussion, or traumatic brain injury.
Head injuries can be open or closed. A closed injury does not break through the skull. With an open, or penetrating, injury, an object pierces the skull and enters the brain. Closed injuries are not always less severe than open injuries.
Some common causes of head injuries are falls, motor vehicle accidents, violence, and sports injuries.
It is important to know the warning signs of a moderate or severe head injury. Get help immediately if the injured person has
- A headache that gets worse or does not go away
- Repeated vomiting or nausea
- Convulsions or seizures
- An inability to wake up
- Dilated (enlarged) pupil in one or both eyes
- Slurred speech
- Weakness or numbness in the arms or legs
- Loss of coordination
- Increased confusion, restlessness, or agitation
Doctors use a neurologic exam and imaging tests to make a diagnosis. Treatment depends on the type of injury and how severe it is.
