Is D84 billable?
No — D84 is a non-billable header code. D84 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 7 billable codes beneath D84.

Excludes1 — never code together — inherited from D80-D89
The conditions below can never be reported together with D84 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 3
The conditions below are not part of D84, but a patient may have both at the same time. When documentation supports it, D84 and the excluded code may both be reported.
- autoimmune disease (systemic) NOS (M35.9)
