O35.7 — Maternal care for (suspected) damage to fetus by other medical procedures
O35.7 is a non-billable header ICD-10-CM code for maternal care for (suspected) damage to fetus by other medical procedures. 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 O35. 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 O35 that has a 7th character of 1 through 9.

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

Other codes that can never be billed with O35.7
These codes carry an Excludes1 note pointing at O35.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O35.7 alone.
- O09.829Supervision of pregnancy with history of in utero procedure during previous pregnancy, unspecified trimester
Risk adjustment
O35.7 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.
How O35.7 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to O35.7.
