Final answer:
The appropriate N18 Chronic Kidney Disease (CKD) code should be reported to identify the CKD stage. The secondary diagnosis could be from I10-I15 if the patient has hypertensive disease, E11-E14 if the patient has diabetes mellitus. The codes Z86.73 and I60-I67 could be used if the patient has a history of TIA or cerebrovascular diseases.
Step-by-step explanation:
Yes, the code from category N18 Chronic Kidney Disease (CKD) should be reported to identify the stage of the CKD. However, the choice of secondary diagnosis code depends on the specifics of the patient's medical history. If the patient has a concurrent diagnosis of hypertension, the appropriate codes would be from category I10-I15 Hypertensive diseases. If diabetes, then the codes from category E11-E14 Diabetes mellitus would be appropriate. Codes from categories Z86.73 Personal history of transient ischemic attack (TIA) and I60-I67 Cerebrovascular diseases could also be reported as secondary diagnoses if they are part the patient's medical history.
