An OB/GYN office documents supervision of a normal first pregnancy at 28 weeks with no complications. Which coding concept best guides ambulatory obstetric diagnosis selection?
Select an answer to reveal the explanation.
Short Explanation
Healthy prenatal visits still live in the pregnancy chapter—they're not a generic physical. At 28 weeks you're in the third-trimester lane for routine supervision of a first pregnancy, and the chart's weeks help nail the right encounter detail.
Full Explanation
Routine outpatient prenatal care for an uncomplicated pregnancy is reported with supervision-of-normal-pregnancy codes (or related pregnancy chapter concepts as documentation supports), not as an incidental pregnancy Z-status alone or as a non-obstetric wellness exam when the visit is prenatal supervision. ICD-10-CM pregnancy coding commonly requires trimester and, when available, weeks of gestation to complete the diagnostic statement. Postpartum codes apply after delivery, not during ongoing antepartum supervision at 28 weeks.
