Excludes1 — never code together — inherited from Chapter 4
The conditions below can never be reported together with E70 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)
Excludes1 — never code together — inherited from E70-E88
The conditions below can never be reported together with E70 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 E70-E88
The conditions below are not part of E70, but a patient may have both at the same time. When documentation supports it, E70 and the excluded code may both be reported.
- Ehlers-Danlos syndromes (Q79.6-)

How long has E70 existed?
E70 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
