Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the Z59 Code Range

Housing and money problems can affect a person's circumstances. This category includes homelessness, inadequate housing, difficulty getting enough food, and limited financial resources.

Z59.0 separates sheltered from unsheltered homelessness. Z59.1 distinguishes inadequate housing related to temperature, utilities, or other conditions. Other categories address conflict with neighbors or landlords, problems living in a residential institution, food insecurity, poverty, and low income.

Z59.7 separates insufficient health insurance coverage from insufficient welfare support. Under Z59.8, housed people experiencing housing instability are distinguished by risk of homelessness or past homelessness. Other subdivisions identify transportation insecurity, financial insecurity, and material hardship due to limited resources.

FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, deleted Z59.86.
