I agree with Debra, ICD9 guidelines state there is an assumed a relationship between HTN & CKD.
White coat syndrome - the stress of being in the doctors office causes temporary increase in blood pressure. One elevated reading does not constitute a diagnosis of hypertension.
Here are some ICD9 guidelines:
Hypertension, Transient
Assign code 796.2, Elevated blood pressure reading without diagnosis of hypertension, unless patient has an established diagnosis of hypertension. Assign code 642.3x for transient hypertension of pregnancy.
ICD-9-CM Official Guidelines for Coding and Reporting Effective October 1, 2011 Page 38 of 107
Hypertensive Chronic Kidney Disease
Assign codes from category 403, Hypertensive chronic kidney disease, when conditions classified to category 585 or code 587 are present with hypertension.
ICD-9-CM Official Guidelines for Coding and Reporting Effective October 1, 2011 Page 36 of 107
From a medical perspective hypertension/diabetes usually causes chronic kidney disease. The treatment of CKD consists of getting control of the disease causing the kidney damage. You might want to query your physician as to what is the true underlying cause. If there has not been a definitive diagnosis of HTN then Hypertensive chronic kidney disease should not be reported.
