Pre-exist hyp heart and chr kidney dis comp preg, third tri

This code signifies a pregnant patient in her third trimester who has a pre-existing history of both hypertensive heart disease and chronic kidney disease. These pre-existing conditions are actively complicating the current pregnancy, indicating a higher risk for both mother and fetus.

Apply this code when documentation clearly states a pregnant patient in her third trimester has pre-existing hypertension affecting the heart and pre-existing chronic kidney disease, and these conditions are impacting the pregnancy. Supporting documentation includes physician notes detailing the pre-existing nature of both conditions and their current influence on the pregnancy.

• Ensure documentation explicitly states "pre-existing" for both hypertensive heart disease and chronic kidney disease.
• Verify the pregnancy is in the third trimester; otherwise, a different trimester-specific code should be used.
• Do not use this code if the hypertension or kidney disease is gestational or developed during the current pregnancy.
