How is O41.10 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to O41.10. They show the wording a clinician may have documented, which often differs from the Tabular description.

Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O41.10 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.-)
Excludes1 — never code together — inherited from O41
The conditions below can never be reported together with O41.10 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- encounter for suspected maternal and fetal conditions ruled out (Z03.7-)
Use additional code — inherited from Chapter 15
Report an additional code alongside O41.10 to fully describe the condition. O41.10 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 O41.10, but a patient may have both at the same time. When documentation supports it, O41.10 and the excluded code may both be reported.
