Excludes1 — never code together
The conditions below can never be reported together with F07.81 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code
Report an additional code alongside F07.81 to fully describe the condition. F07.81 is sequenced first.
- code to identify associated post-traumatic headache, if applicable (G44.3-)
Code also
Two codes may be needed to describe the condition fully. Whether F07.81 is sequenced first depends on the reason for the encounter.
- , if applicable, sequela of concussion (S06.0X- with seventh character S)
Inclusion terms
Alternative wording in documentation that is classified to F07.81.

Code first — inherited from F07

Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F07.81, but a patient may have both at the same time. When documentation supports it, F07.81 and the excluded code may both be reported.
