2027 ICD-10-CM Diagnosis Code E36.01Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure
ICD-10-CM Codes›E00–E89›E36›E36
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
E36.01 is a billable ICD-10-CM diagnosis code for intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 919 through 921. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 80 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Postprocedural or postoperative endocrine or metabolic complication.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to E36.01: its own notes plus those printed at E36.0, E36, and Chapter 4. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- intraoperative hemorrhage and hematoma of an endocrine system organ or structure due to accidental puncture or laceration during a procedure (E36.1-)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Notes
General instructions on how these codes are used.
- All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Questions About E36.01Overview
Is E36.01 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does E36.01 group to?
When intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure is the principal diagnosis on an inpatient stay, it groups to MS-DRG 920, 919, 921, with relative weights from 0.6719 to 1.7624 depending on complications. Higher weights mean higher Medicare reimbursement.
Is E36.01 a CC or MCC?
CMS lists E36.01 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 80 closely related codes in its exclusion list.
Can E36.01 be reported with a code from E36.1?
Not as a rule. The Excludes1 note at E36.0, which applies to E36.01, lists "intraoperative hemorrhage and hematoma of an endocrine system organ or structure due to accidental puncture or laceration during a procedure (E36.1-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of E36.01?
Under the General Equivalence Mappings, intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure converts to ICD-9-CM 998.11 (hemorrhage complic proc) and 998.12 (hematoma complic proc). The mapping is approximate, so confirm the match fits the documentation.
