Oth pregnancy related conditions, first trimester

This code identifies various pregnancy-related conditions not classified elsewhere, specifically occurring during the first trimester. These are conditions that are directly attributable to the pregnancy but do not have a more specific ICD-10-CM code.

Apply this code when documentation indicates a pregnancy-related condition in the first trimester that is not covered by a more specific O-code. Examples include unusual but non-specific symptoms or complications directly linked to the pregnancy's physiological changes, such as persistent, atypical abdominal discomfort not due to labor or miscarriage, or unusual skin changes unique to pregnancy. The medical record must clearly state the condition and its occurrence within the first trimester.

• Always sequence this code after the primary reason for the encounter if the condition is a complication.
• Ensure documentation explicitly states "first trimester" or provides gestational age that falls within the first trimester (0-13 weeks 6 days).
• Avoid using this code if a more specific O-code exists for the documented pregnancy complication.
