Q: When is code I12.9 used?  I thought that was for hypertension with CKD without CHF?

A: Code I12.9 is for hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease.  This code is used when the patient has hypertension and CKD without heart disease.  A patient with hypertension and CKD and heart disease is classified to category I13.  Please note that code I13.0- (Hypertensive heart and chronic kidney disease) on slide 39 in the presentation should have been I12.- (Hypertensive chronic kidney disease with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease.  However, if the patient had hypertension, hypertensive heart disease, CKD, and diabetes, the codes listed on slide 39 are correct.

Q: In polling question #3, shouldn’t the code for ESRD with hypertension be I12.0?  If documentation says ESRD due to DM and pt has HTN. Do you still code as HTN and DM is related?

A: You are correct that in polling question #2, code I13.11 should be I12.0.  However, the correct answer in this case is still answer #2, E11.22, N18.6, and I10 since the ESRD was specifically linked to the diabetes.  Coding Clinic, Third Quarter 2019: Page 3 states: “When the patient has diabetes, hypertension and chronic kidney disease (CKD) and the provider documents CKD due to diabetes or diabetic CKD, diabetic nephropathy or other similar terminology a causal relationship is indicated, and denotes the CKD is not related to the hypertension. In this case, assign a code for diabetic chronic kidney disease. Do not assign a code for hypertensive CKD, as the hypertension would be coded separately.”

Q: When doctor writes type 1.5 diabetes treated as type 2, I’m told to code as type 2, just wanted to verify.

A: Per Coding Clinic, Third Quarter, 2018: Page 4, type 1.5 diabetes mellitus is assigned to category E13, Other specified diabetes mellitus.  It is incorrect to code it as type 2 diabetes mellitus.

Q: How do you code for gestational diabetes controlled by injectable non-insulin medications?  The codes allow for reporting of GDM controlled by diet, insulin, or oral hypoglycemic drugs, but the 2021 guidelines don’t address injectable non-insulin medication.

A: According to our clinical sources, it is clinically unfeasible that a patient with gestational diabetes mellitus (GDM) would be given an injectable non-insulin medication.
