Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- current nicotine dependence (F17.2-)
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.
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.

What is the ICD-10 code for personal history of nicotine dependence?
The ICD-10-CM code for personal history of nicotine dependence is Z87.891 (sometimes written as Z87891). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Z87.891 (Personal history of other specified conditions) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of nicotine dependence on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Z87.891 group to?
On inpatient claims, personal history of nicotine dependence 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 Z87.891 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of nicotine dependence describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z87.891 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 nicotine dependence 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.
