Maternal care for damage to fetus by drugs, fetus 3

This code signifies medical attention provided to a pregnant patient due to concerns or confirmed evidence that illicit or prescribed drug exposure has caused harm or abnormalities to the developing fetus. This includes situations where the mother's drug use (e.g., opioids, cocaine, alcohol, certain medications) is suspected or known to have adversely affected fetal development. The "3" in the final character indicates a third trimester encounter.

Use this code when documentation clearly indicates maternal care focused on monitoring, evaluating, or managing a pregnancy where the fetus is believed to have been damaged by maternal drug exposure during the third trimester. This applies to both recreational and prescribed drugs with known teratogenic effects. Supporting documentation would include physician notes detailing drug exposure, fetal anomalies, growth restriction, or other adverse fetal outcomes attributed to drugs.

• Ensure the documentation specifies the third trimester for this specific code; otherwise, a different trimester character (1 or 2) would be used.
• Always code the specific drug exposure (e.g., T40.2X1- for opioid use) as an additional diagnosis to provide a complete clinical picture.
• Do not use this code for fetal abnormalities due to genetic causes or other non-drug-related factors.
