These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
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.

Traveler's Health
Traveling can increase your chances of getting sick. A long flight can increase your risk for deep vein thrombosis. Once you arrive, it takes time to adjust to the water, food, and air in another place. Water in developing countries can contain viruses, bacteria, and parasites that cause stomach upset and diarrhea.

Questions About Z71.84Overview
Is Z71.84 (Other specified counseling) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report encounter for health counseling related to travel on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z71.84 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because encounter for health counseling related to travel describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z71.84 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 encounter for health counseling related to travel on inpatient claims.
