Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to Z72.0: its own notes plus those printed at Z72 and Chapter 21. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Tobacco use NOS
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
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.
- 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.

Questions About Z72.0Overview
What is the ICD-10 code for tobacco use?
The ICD-10-CM code for tobacco use is Z72.0 (sometimes written as Z720). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z72.0 (Problems related to lifestyle) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report tobacco use on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z72.0 group to?
On inpatient claims, tobacco use 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 Z72.0 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because tobacco use describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z72.0 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 tobacco use on inpatient claims. The code appears in the Persons encountering health services in other circumstances (Z69-Z76) range of the CMS exempt list.
