Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O45 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- supervision of normal pregnancy (Z34.-)
Use additional code — inherited from Chapter 15
Report an additional code alongside O45 to fully describe the condition. O45 is sequenced first.
- code, if applicable, from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known.
Excludes2 — not included here — inherited from Chapter 15
The conditions below are not part of O45, but a patient may have both at the same time. When documentation supports it, O45 and the excluded code may both be reported.
