Post-traumatic headache, unspecified, intractable

This code signifies a headache that develops following a traumatic injury, where the specific type of headache is not documented, and it is resistant to standard medical treatment. The intractable nature indicates that the headache is severe and persistent despite therapeutic interventions.

Use this code for patients presenting with a chronic, debilitating headache clearly linked to a prior physical trauma, where the headache type (e.g., tension, migraine) is not specified by the provider, and treatment has been unsuccessful. Documentation must explicitly state "post-traumatic headache" and "intractable" or describe the headache as resistant to treatment.

• Ensure documentation clearly links the headache to a traumatic event and specifies its intractable nature.
• Do not use this code if the specific type of post-traumatic headache (e.g., migraine, tension-type) is documented; instead, use the more specific code.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when managing other conditions alongside the intractable post-traumatic headache.
