E36Intraoperative complications of endocrine system

Non-billable headerICD-10-CM

E36 is a non-billable header ICD-10-CM code for intraoperative complications of endocrine system. 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.

  • postprocedural endocrine and metabolic complications and disorders, not elsewhere classified (E89.-)

Other codes that can never be billed with E36

These codes carry an Excludes1 note pointing at E36. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E36 alone.

  • E36.0Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating a procedure

Risk adjustment

E36 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 E36

3 child codes. Green means billable.
