What 59425 covers
This code represents routine prenatal care across four to six visits, such as monitoring maternal and fetal status, assessing pregnancy progress, and managing common prenatal concerns. Obstetricians and other clinicians providing pregnancy care may report it in office or other outpatient settings when their services cover the antepartum portion rather than the full obstetrical package.
Select the code based on the documented number of antepartum visits: four through six, rather than seven or more. Keep records supporting the visit count and the prenatal care provided. The code is reported for the antepartum care course, not once for each visit. CMS classifies it as a maternity code, so the usual global surgery rules do not apply; it is not assigned a standard surgical global period.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
