Personal and family history codes
support the need for screening and
follow-up exams.

a disease, has the sequelae or residual of a past disease or condition, or has another factor influencing his or her health status.

Since status codes may affect the course of treatment and its outcome, the codes are used to track public health issues. For example, the status codes for infection with drug-resistance microorganism are assigned as an additional code for infectious conditions to indicate the presence of the drug-resistant infectious organism (see “Inpatient, Acute Care—Status Scenario”).

Outpatient Prenatal Visits

In ICD-9-CM a code from category V23, Supervision of high-risk pregnancy, should be used as the first-listed diagnosis for routine prenatal outpatient visits for patients with high-risk pregnancies unless a pertinent tabular category V23 exclude note applies. When appropriate, secondary chapter 11 codes may be reported with category V23 codes.

In contrast, ICD-10-CM does not include Z code prenatal visits for supervision of high-risk pregnancy. Rather, routine prenatal outpatient visits for patients with high-risk pregnancies are assigned a code from chapter 15, category O09, Supervision of high-risk pregnancy, as the first-listed diagnosis. ¢
