E89 — Postprocedural endocrine and metabolic complications and disorders, not elsewhere classified

Non-billable headerICD-10-CM

E89 is a non-billable header ICD-10-CM code for postprocedural endocrine and metabolic complications and disorders, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

intraoperative complications of endocrine system organ or structure (E36.0-, E36.1-, E36.8)

Other codes that can never be billed with E89

These codes carry an Excludes1 note pointing at E89. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E89 alone.

N95Menopausal and other perimenopausal disorders
N95.1Menopausal and female climacteric states
R29.0Tetany
R73Elevated blood glucose level
E28Ovarian dysfunction
E28.8Other ovarian dysfunction
E03Other hypothyroidism
E20Hypoparathyroidism

Risk adjustment

E89 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead E89

8 child codes. Green means billable.
