Headache following some kind if trauma, such as whiplash or a blow to the head, has a special classification as post-traumatic.
Diagnostic codes are unique for this type of headache, and distinguish it from other headaches, such as migraines, tension headaches, sinus headaches, etc.
A post-traumatic headache may require a more extensive course of treatment. Your doctor’s use of the pertinent diagnostic codes alerts insurance companies and auxiliary caregivers, and are important to justify additional care that may be needed by the patient.
