Personal risk factors, not elsewhere classified

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 7 more specific codes instead:

  • Z91.0 Allergy status, other than to drugs and biological substances (also a header)
  • Z91.1 Patient's noncompliance with medical treatment and regimen (also a header)
  • Z91.4 Personal history of psychological trauma, not elsewhere classified (also a header)
  • Z91.5 Personal history of self-harm (also a header)
  • Z91.8 Other specified personal risk factors, not elsewhere classified (also a header)
  • Z91.A Caregiver's noncompliance with patient's medical treatment and regimen (also a header)
  • Z91.B Personal risk factor of exposure to diethylstilbestrol

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
