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

This code signifies a pregnant patient in her second trimester who has a pre-existing condition 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 diagnosis of pre-existing hypertensive heart disease and chronic kidney disease in a pregnant patient during her second trimester. The medical record must explicitly link these pre-existing conditions as complicating the pregnancy, not merely co-occurring.

• Ensure documentation specifies "pre-existing" to differentiate from gestational hypertension or new-onset kidney disease during pregnancy.
• Verify the trimester of pregnancy is clearly documented as the second trimester.
• Do not use this code if only one of the conditions (hypertensive heart disease or chronic kidney disease) is present; both must be pre-existing and complicating the pregnancy.
