Pre-exist hyp chronic kidney disease comp preg, third tri

This code signifies a pregnant patient in her third trimester who has a pre-existing history of hypertension that has led to chronic kidney disease. The chronic kidney disease is a direct complication of her pre-existing hypertension and is now impacting the current pregnancy.

Apply this code when documentation clearly indicates a pregnant patient in her third trimester with a pre-existing diagnosis of hypertensive chronic kidney disease. This code is appropriate when the chronic kidney disease is explicitly stated as a complication of the pre-existing hypertension during the current pregnancy.

• Always confirm the trimester of pregnancy from the medical record.
• Ensure documentation specifies "pre-existing" hypertension and that the chronic kidney disease is a complication of this hypertension.
• Do not use if the hypertension or kidney disease developed during the current pregnancy (gestational).
