How is O35.08 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to O35.08. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Pregnancy › complicated by › fetal › spina bifida (single) (uterine)

Excludes1 — never code together — inherited from Chapter 15

  • supervision of normal pregnancy (Z34.-)

Excludes1 — never code together — inherited from O35

The conditions below can never be reported together with O35.08 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 O35.08 to fully describe the condition. O35.08 is sequenced first.
