New and revised ICD-10-CM obstetric guidelines

摘要

WHEN COMPARING THE ICD-9-CM and ICD-10-CM obstetric guidelines, coding professionals should note both revised and completely new guidelines in ICD-10-CM. These guidelines are a result of various new concepts introduced in Chapter 15 of ICD-10-CM, such as the addition of a seventh character to identify the fetus in a multiple gestation affected by the condition being coded. Some of these new and revised ICD-10-CM obstetric guidelines are highlighted below.This new ICD-10-CM guideline for the final character indicates that many of the Chapter 15 codes specify the trimester of the pregnancy. A note at the beginning of Chapter 15 defines the timeframes for the three trimesters. The assignment of the final character for trimester is based on either the provider's documentation of the trimester-or the number of weeks of gestation-for the current admission/encounter.
