O36.2 — Maternal care for hydrops fetalis

Non-billable headerICD-10-CM

O36.2 is a non-billable header ICD-10-CM code for maternal care for hydrops fetalis. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

One of the following 7th characters is to be assigned to each code under category O36. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O36 that has a 7th character of 1 through 9.

0: not applicable or unspecified
1: fetus 1
2: fetus 2
3: fetus 3
4: fetus 4
5: fetus 5
9: other fetus

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Maternal care for hydrops fetalis NOS
Maternal care for hydrops fetalis not associated with isoimmunization

Risk adjustment

O36.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead O36.2

4 child codes. Green means billable.
