Questions About O32Overview

What is the ICD-10 code for maternal care for malpresentation of fetus?

O32 is the ICD-10-CM category for maternal care for malpresentation of fetus, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is O32 (Maternal care for malpresentation of fetus) a billable code?

No. This is a category header that groups the codes for maternal care for malpresentation of fetus, and headers cannot be submitted on claims. Claims for maternal care for malpresentation of fetus need a more specific code from this category, such as O32.0XX0, O32.0XX1, and O32.0XX2.

Can O32 be reported with a code from O64?

Not as a rule. The Excludes1 note on O32 lists "malpresentation of fetus with obstructed labor (O64.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
