Supervision of elderly primigravida, third trimester

This code signifies the ongoing medical management and monitoring of a pregnant patient who is 35 years of age or older, experiencing her first pregnancy, and is currently in her third trimester. It indicates that the pregnancy is being supervised due to the advanced maternal age, which is considered a risk factor.

Apply this code when a primigravid patient, aged 35 or older, is receiving antenatal care during her third trimester. Documentation should clearly state the patient's age, primigravid status, and the current trimester of pregnancy.

• Ensure the patient's age (35 or older) and primigravida status are explicitly documented.
• Verify the current trimester of pregnancy; this code is specific to the third trimester.
• Do not use this code if the patient is multiparous, regardless of age.
