Is E66.8 billable?
No — E66.8 is a non-billable header code. E66.8 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 E66.8.

Excludes1 — never code together — inherited from Chapter 4
The conditions below can never be reported together with E66.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- transitory endocrine and metabolic disorders specific to newborn (P70-P74)
Code first — inherited from E66
The underlying condition below must be sequenced before E66.8. E66.8 describes a manifestation and cannot be the principal or first-listed diagnosis.
- obesity complicating pregnancy, childbirth and the puerperium, if applicable (O99.21-)
Use additional code — inherited from E66
Report an additional code alongside E66.8 to fully describe the condition. E66.8 is sequenced first.
Excludes2 — not included here — inherited from E66
The conditions below are not part of E66.8, but a patient may have both at the same time. When documentation supports it, E66.8 and the excluded code may both be reported.
