Final answer:
The correct medical codes for a patient admitted with hypertensive kidney disease, CKD stage III, and acute systolic congestive heart failure are I13.2, I50.9, and N18.3. These codes reflect accurate stages of CKD and associated conditions for proper diagnosis and treatment planning in the medical setting.
Step-by-step explanation:
Correct Coding for a Patient with Multiple Health Issues
A patient admitted with hypertensive kidney disease, CKD stage III, and acute systolic congestive heart failure should be correctly coded in medical records for accurate diagnosis and billing purposes. The correct ICD-10-CM codes for this scenario would be as follows: hypertensive kidney disease with stage 1 through stage 4 chronic kidney disease is classified to code I13.2; heart failure, unspecified is classified as I50.9; and chronic kidney disease, stage 3 is classified as N18.3. Therefore, the correct option for coding these conditions is (a) I13.2, I50.9, N18.3.
The progression of CKD is typically measured by serum creatinine and GFR (glomerular filtration rate), where stage 1 CKD is slightly diminished function with relatively normal GFR, and stage 5 CKD is severe, requiring renal replacement therapy. In this case, the patient has stage 3 CKD, which is a moderate decrease in kidney function.
CKD can lead to complications like congestive heart failure, which may present as pre-renal causes for proteinuria, as the failing heart leads to compromised kidney perfusion. Acute on chronic renal failure (AoCRF) may present in such a scenario, where the acute worsening of renal function occurs on the background of CKD. Accurate ICD-10 coding is essential for the proper management and treatment of the patient's conditions.
