Excludes1 — never code together
The conditions below can never be reported together with P39.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- gonococcal conjunctivitis (A54.31)
Inclusion terms
Alternative wording in documentation that is classified to P39.1.
- Neonatal chlamydial conjunctivitis
- Ophthalmia neonatorum NOS
Use additional code — inherited from P39
Report an additional code alongside P39.1 to fully describe the condition. P39.1 is sequenced first.
- code to identify organism or specific infection
Excludes2 — not included here — inherited from Chapter 16
The conditions below are not part of P39.1, but a patient may have both at the same time. When documentation supports it, P39.1 and the excluded code may both be reported.
