Coding Clinic tackles HTN and renal sclerosis coding

These Q&As come from the Coding Clinic, Fourth Quarter 2010 Page: 137 Coding advice or code assignments contained in this issue effective with discharges October 1, 2010.

Question:
A patient seen in the physician’s office was diagnosed with renal sclerosis due to hypertension. I understand that this should be coded with a code from category 403, Hypertensive chronic kidney disease, but I’m unable to determine what 5th digit should be applied. Please provide some clarification.
Answer:
Assign code 403.90, Hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage I through stage IV, or unspecified. The fifth digit of “0” should be assigned since there is no chronic kidney disease stage specified. In addition, assign also code 587, Renal sclerosis, unspecified.

Question:
A patient with renal sclerosis due to hypertension and stage V chronic kidney disease (CKD) is seen in the doctor’s office. How should this be coded?
Answer:
Assign code Assign code 403.91, Hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage V or end stage renal disease; code 587, Renal sclerosis, unspecified; and code 585.5, Chronic kidney disease, stage V, for a patient with hypertension due to renal sclerosis and stage V CKD. The fifth digit for subcategory 403.9 is selected on the basis of the documented CKD stage.
