Excludes1 — never code together — inherited from F13.9
The conditions below can never be reported together with F13.959 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F13.959, but a patient may have both at the same time. When documentation supports it, F13.959 and the excluded code may both be reported.
- symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)
