Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O26 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 O26 to fully describe the condition. O26 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 O26, but a patient may have both at the same time. When documentation supports it, O26 and the excluded code may both be reported.
Excludes2 — not included here — inherited from O20-O29
The conditions below are not part of O26, but a patient may have both at the same time. When documentation supports it, O26 and the excluded code may both be reported.
