Maternal care for known or suspected fetal abnormality and damage - O35
This notation helps users understand the scope of a code O35 category and provides additional information about the conditions or terms that fall under that category.
Category Includes:
- the listed conditions in the fetus as a reason for hospitalization or other obstetric care to the mother, or for termination of pregnancy
Excludes1: It indicates that the conditions described by two codes cannot occur together in the same patient. These codes are mutually exclusive.
Type 1 Excludes:
- encounter for suspected maternal and fetal conditions ruled out (Z03.7-)
Code Also: It indicates that an additional code should be used alongside the primary code to capture related factors or associated conditions.
Category codeAlso:
- any associated maternal condition
The seventh character in ICD-10-CM is an essential component that adds specificity to diagnosis codes by indicating aspects like the encounter type, stage, or other relevant clinical details.
Category SevenChr Note:
- 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.
