Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Z85: its own notes plus those printed at block Z77-Z99 and Chapter 21. A note printed at a category, block or chapter applies to every code under it.

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.

  • personal history of benign neoplasm (Z86.01-)
  • personal history of carcinoma-in-situ (Z86.00-)

Code First

The underlying condition named in the note is sequenced before this code.

  • any follow-up examination after treatment of malignant neoplasm (Z08)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code to identify:
  • alcohol use and dependence (F10.-)
  • exposure to environmental tobacco smoke (Z77.22)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

From Block Z77-Z99 Persons with potential health hazards related to family and personal history and certain conditions influencing health status applies to 567 codes
  • any follow-up examination (Z08-Z09)

Notes

General instructions on how these codes are used.

From Chapter 21 (Z00-Z99) Factors influencing health status and contact with health services applies to 1,425 codes
  • 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.

  • Z08 Encounter for follow-up examination after completed treatment for malignant neoplasm
    code to identify the personal history of malignant neoplasm (Z85.-)
  • Z15.0 Genetic susceptibility to malignant neoplasm
    code, if applicable, for any personal history of malignant neoplasm (Z85.-)

Patient EducationClinical

Cancer

Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.
