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

This code signifies a pregnant patient in her second trimester who has a pre-existing diagnosis of chronic kidney disease (CKD) that is directly linked to or caused by pre-existing hypertension. The CKD is a chronic condition that existed prior to the current pregnancy.

Apply this code when documentation clearly states a patient is in her second trimester, has a history of hypertension, and has been diagnosed with CKD as a consequence of that hypertension, with the CKD complicating the current pregnancy. Supporting documentation includes physician notes detailing the patient's medical history, current pregnancy stage, and the impact of the pre-existing hypertensive CKD on the pregnancy.

• Always confirm the trimester of pregnancy; incorrect trimester assignment is a common error.
• Ensure documentation explicitly links the CKD to pre-existing hypertension, not gestational hypertension or other causes.
• Sequence this code as a primary diagnosis when the hypertensive CKD is the main reason for the encounter, or as a secondary diagnosis when it's a significant co-morbidity.
