Inclusion terms
Alternative wording in documentation that is classified to O36.0.
- Maternal care for Rh incompatibility (with hydrops fetalis)
Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O36.0 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 O36
The conditions below can never be reported together with O36.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 15
Report an additional code alongside O36.0 to fully describe the condition. O36.0 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 O36.0, but a patient may have both at the same time. When documentation supports it, O36.0 and the excluded code may both be reported.
