Decreased fetal movements, unsp trimester, unsp

This code signifies a maternal condition where the pregnant patient reports a reduction in the frequency or strength of fetal movements, without further specification of the trimester. It indicates a concern for fetal well-being that requires further evaluation.

Apply this code when documentation clearly states "decreased fetal movements" or "reduced fetal activity" and the trimester is not specified or is not applicable to the clinical context. This is often used as an initial diagnosis when a patient presents with this complaint before a more definitive cause or specific trimester can be determined.

• Only use this code when the trimester is truly unspecified or not relevant to the clinical encounter.
• Prioritize more specific codes (O36.811-, O36.812-, O36.813-) if the trimester is documented.
• Always sequence this code as a maternal complication affecting management of pregnancy, childbirth, and the puerperium.
