Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Z13: its own notes plus those printed at block Z00-Z13 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.

  • Screening is the testing for disease or disease precursors in asymptomatic individuals so that early detection and treatment can be provided for those who test positive for the disease.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • encounter for diagnostic examination-code to sign or symptom

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.

From Block Z00-Z13 Persons encountering health services for examinations applies to 156 codes
  • examinations related to pregnancy and reproduction (Z30-Z36, Z39.-)

Notes

General instructions on how these codes are used.

From Block Z00-Z13 Persons encountering health services for examinations applies to 156 codes
  • Nonspecific abnormal findings disclosed at the time of these examinations are classified to categories R70-R94.
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.
