ICD-10 Code for Abortion
Also indexed as (complete) (spontaneous)
The ICD-10-CM code for abortion is O03.9 — Complete or unspecified spontaneous abortion without complication. This is the code the Alphabetic Index gives for abortion with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
O03.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which abortion code should you use?
The Alphabetic Index lists 62 codes under Abortion. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
