Z01.811Encounter for preprocedural respiratory examination

Billable / specific codeICD-10-CMPOA exempt

Z01.811 is a billable, specific ICD-10-CM code for encounter for preprocedural respiratory examination. It is valid for submission on a claim.

Excludes1 inherited from the categories above Z01.811

These are not written on Z01.811, but they bind it: a note on a category applies to every code beneath it. Billing Z01.811 with anything listed here is a denial.

Written on Z01 Encounter for other special examination without complaint, suspected or reported diagnosis

  • encounter for examination for administrative purposes (Z02.-)
  • encounter for examination for suspected conditions, proven not to exist (Z03.-)
  • encounter for laboratory, radiologic and imaging examinations for sign(s) and symptom(s) - code to the sign(s) or symptom(s)

Excludes2 inherited from the categories above Z01.811

Also inherited, and the opposite of Excludes1: these conditions are not part of Z01.811, but a patient can have both, so you may code both.

Written on Z01 Encounter for other special examination without complaint, suspected or reported diagnosis

  • encounter for laboratory and radiologic examinations as a component of general medical examinations (Z00.0-)
  • screening examinations (Z11-Z13)

Risk adjustment

Z01.811 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

Z01.811 is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
