Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to Z86.011: its own notes plus those printed at Z86.0, Z86, block Z77-Z99, and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Excludes2

Code First
The underlying condition named in the note is sequenced before this code.
Code Also
A second code may be needed to fully describe the condition; the note gives no sequencing direction.
Notes
General instructions on how these codes are used.
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Benign Tumors
Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

The ICD-10-CM code for personal history of benign neoplasm of the brain is Z86.011 (sometimes written as Z86011). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z86.011 (Personal history of benign neoplasm) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of benign neoplasm of the brain on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z86.011 group to?
On inpatient claims, personal history of benign neoplasm of the brain maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.5574. Higher weights mean higher Medicare reimbursement.
Can Z86.011 be a principal diagnosis?

Is Z86.011 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for personal history of benign neoplasm of the brain on inpatient claims. The code appears in the Persons with potential health hazards related to family and personal history and certain conditions influencing health status (Z77-Z99) range of the CMS exempt list.
