Supervision of high risk pregnancy, unsp, third trimester

This code signifies the ongoing medical oversight of a pregnancy that has been identified as high-risk, but the specific reason for the high-risk designation is not documented. This particular code specifies that the patient is in her third trimester of pregnancy. It indicates that the patient requires closer monitoring due to potential complications affecting either the mother or the fetus, without detailing the nature of those risks.

Use this code when a pregnant patient in her third trimester is receiving enhanced prenatal care due to a high-risk factor, but the medical record lacks specific documentation of the underlying high-risk condition. This code is appropriate when the provider's documentation clearly states "supervision of high-risk pregnancy, unspecified" or similar language, and the gestational age confirms the third trimester. It should be used when more specific high-risk codes (e.g., for pre-eclampsia, diabetes in pregnancy) cannot be assigned due to insufficient detail.

• Always strive for a more specific high-risk pregnancy code if the documentation allows.
• Ensure the documentation explicitly states "third trimester" or provides gestational weeks that fall within the third trimester (typically week 28 to delivery).
• This code should be a secondary diagnosis, with the primary diagnosis often being the reason for the encounter or a more specific pregnancy complication if available.
