E36.01

E36.01 — Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure

Billable / specific codeICD-10-CM

E36.01 is a billable, specific ICD-10-CM code for intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure. It is valid for submission on a claim.

Excludes1 inherited from the categories above E36.01

These are not written on E36.01, but they bind it: a note on a category applies to every code beneath it. Billing E36.01 with anything listed here is a denial.

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

intraoperative hemorrhage and hematoma of an endocrine system organ or structure due to accidental puncture or laceration during a procedure (E36.1-)

Excludes2 inherited from the categories above E36.01

Also inherited, and the opposite of Excludes1: these conditions are not part of E36.01, but a patient can have both, so you may code both.

Written on E36 — Intraoperative complications of endocrine system

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

Risk adjustment

E36.01 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.

Medicare coverage

E36.01 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
