*I would say do not code the headache's. If the jaw pain is a late effect of the concussion, then I would use 907.0 and 784.92. If current concussion then 850.9, 784.92. Hope this helps.
Symptoms
By Mayo Clinic staff
The signs and symptoms of a concussion can be subtle and may not be immediately apparent. Symptoms can last for days, weeks or even longer.
The most common symptoms after a concussive traumatic brain injury are headache, amnesia and confusion. The amnesia, which may or may not be preceded by a loss of consciousness, almost always involves the loss of memory of the impact that caused the concussion.
Signs and symptoms of a concussion may include:
Headache or a feeling of pressure in the head
Temporary loss of consciousness
Confusion or feeling as if in a fog
Amnesia surrounding the traumatic event
Dizziness or "seeing stars"
Ringing in the ears
Nausea or vomiting
Slurred speech
Fatigue
Some symptoms of concussions may be immediate or delayed in onset by hours or days after injury:
Concentration and memory complaints
Irritability and other personality changes
Sensitivity to light and noise
Sleep disturbances
Psychological adjustment problems and depression
Disorders of taste and smell
Symptoms in children
Head trauma is very common in young children. But concussions can be difficult to recognize in infants and toddlers because they can't readily communicate how they feel. Nonverbal clues of a concussion may include:
Listlessness, tiring easily
Irritability, crankiness
Change in eating or sleeping patterns
Lack of interest in favorite toys
Loss of balance, unsteady walking
