Is I11 billable?
No — I11 is a non-billable header code. I11 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 2 billable codes beneath I11.

Includes
Conditions classified to I11.
Excludes1 — never code together — inherited from I10-I1A
The conditions below can never be reported together with I11 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from I10-I1A
Report an additional code alongside I11 to fully describe the condition. I11 is sequenced first.
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I11, but a patient may have both at the same time. When documentation supports it, I11 and the excluded code may both be reported.
