I13 — Hypertensive heart and chronic kidney disease

Not billable

Is I13 billable?

No — I13 is a non-billable header code. I13 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath I13.
