Code first
The underlying condition below must be sequenced before O34. O34 describes a manifestation and cannot be the principal or first-listed diagnosis.
- any associated obstructed labor (O65.5)
Use additional code
Report an additional code alongside O34 to fully describe the condition. O34 is sequenced first.
- code for specific condition
Includes
Conditions classified to O34.
- the listed conditions as a reason for hospitalization or other obstetric care of the mother, or for cesarean delivery before onset of labor
Excludes1 — never code together — inherited from Chapter 15
The conditions below can never be reported together with O34 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 O34 to fully describe the condition. O34 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 O34, but a patient may have both at the same time. When documentation supports it, O34 and the excluded code may both be reported.
