AAPC CPC Exam - Topic 10 Question 66 Discussion

Posted by James on Jul 15, 2026 at 09:30 PM

What ICD-10-CM coding is reported for a patient who has hypertension and CKD stage 2?

Suggested Answer: B

When hypertension and chronic kidney disease (CKD) are documented together, ICD-10-CM assumes a cause-and-effect relationship.

I12.9 = Hypertensive chronic kidney disease with stage 1--4 CKD

N18.2 = CKD stage 2

I12.0 is only for CKD stage 5 or ESRD, which does not apply here.

Therefore, the correct code combination is I12.9, N18.2.

I agree with A. It specifies the stage of CKD too. Makes sense!

I’m leaning towards B) I12.9, N18.2. It covers unspecified hypertension.

I think it's A) I12.0, N18.2. Seems accurate for both conditions.

CKD stage 2 should definitely be N18.2, no doubt!

Definitely I12.0, N18.2 for that combo.

I definitely recall that I12.0 is for hypertension with CKD, but I can't remember if it's stage 1 or 2. I think I need to review that part again.

I feel like I should know this, but I keep mixing up the codes for hypertension. I might lean towards A or B, but I need to double-check.

I remember practicing a question similar to this, and I think it had to do with the relationship between hypertension and CKD. Maybe B is the right choice?

I think the answer might be A, but I'm not completely sure about the specifics of the hypertension codes.
