In ICD-10-CM, the word “with” should be interpreted to mean “associated with” or “due to” when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular List. The classification presumes a causal relationship between the two conditions when linked by these terms in the Alphabetic Index or Tabular List.
The word “with” is sequenced immediately following the main term in the Alphabetic Index and not in alphabetical order.
The classification presumes a causal relationship between Hypertension and heart involvement and between hypertension and kidney involvement, as the two conditions are linked by the term “with” in the Alphabetic Index. Even in the absence of provider documentation explicitly linking them, these conditions should be coded as related.
ICD-10-CM, 2018 Guidelines instruct you to assume that there is a cause-and-effect relationship between hypertension and chronickidney disease reported with N18.-. The physician might not indicate that the hypertension and Chronic Kidney Disease are related, but the coder is to assume this relationship. Chronic renal failure (CRF), chronic kidney disease (CKD), and chronic renal insufficiency (CRI) when reported with hypertension are reported as follows:
• CRF/CKD/CRI + hypertension I12.9 + N18.9
• CKD stage 1 + hypertension I12.9 + N18.1
• CKD stage 2 + hypertension I12.9 + N18.2
• CKD stage 3 + hypertension I12.0 + N18.3
• CKD stage 4 + hypertension I12.0 + N18.4
• CKD stage 5 + hypertension I12.0 + N18.5
• CKD stage 6 or ESRD or on dialysis + I12.0 + N18.6
• Patient with CKD on any type of dialysis I12.9 + N18.6 + Z99.2
CKD should not be coded as hypertensive if the physician has specifically documented a different cause.
Hypertension may last only temporarily (transient), reported with R03.0, Elevated blood pressure reading without diagnosis of hypertension. If the patient has been diagnosed as having high blood pressure, you cannot subsequently assign a transient hypertension code. If the hypertension occurs during and due to pregnancy, assign O13.- or O14.-based on if there is or is not significant proteinuria (large amount of protein in the urine that results from renal disease or other abnormal condition).
There are no separate codes for benign or malignant hypertension
Hypertension, Secondary
Secondary hypertension is due to an underlying condition so two codes will be required.
Hypertension (accelerated) (benign) (essential) (idiopathic) (malignant) (systemic) is coded to Category I10
