How is O36.2 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to O36.2. They show the wording a clinician may have documented, which often differs from the Tabular description.

Excludes1 — never code together

The conditions below can never be reported together with O36.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • hydrops fetalis associated with ABO isoimmunization (O36.1-)
  • hydrops fetalis associated with rhesus isoimmunization (O36.0-)

Inclusion terms

Alternative wording in documentation that is classified to O36.2.

  • Maternal care for hydrops fetalis not associated with isoimmunization

Excludes1 — never code together — inherited from Chapter 15

Excludes1 — never code together — inherited from O36
