Matern care for abnlt fetl hrt rate or rhym, 1st tri, unsp

This code signifies maternal care provided during the first trimester for any detected irregularity in the fetal heart rate or rhythm. This includes instances where the specific type of abnormality is not documented or is not applicable to further specification. It indicates that the mother is receiving monitoring and management due to concerns about the fetal cardiac activity.

Use this code when a pregnant patient in her first trimester presents with or is diagnosed with an abnormal fetal heart rate or rhythm, and the documentation does not specify the exact nature of the abnormality or it's not clinically relevant for further detail. Supporting documentation would include physician notes detailing fetal heart rate monitoring, ultrasound findings, or clinical assessments indicating an irregular fetal heartbeat during the first trimester.

• Ensure the documentation clearly specifies "first trimester" for this code to be appropriate.
• If a specific fetal heart rate abnormality (e.g., bradycardia, tachycardia) is identified and documented, a more specific code from the O36.83 subcategory should be used.
• This code is for maternal care; do not use it for fetal conditions coded from Chapter 16 (P00-P96).
