CPT code 76815 denotes a limited, targeted ultrasound examination of the fetus focused on one or more specific parameters rather than a full anatomic survey. This code is used when providers perform focused imaging to answer discrete clinical questions—examples include confirming fetal cardiac activity, assessing fetal position, estimating amniotic fluid volume, or documenting growth in select settings. Nationally, use of limited fetal ultrasound affects outpatient obstetric imaging workflow, coding specificity, and claims adjudication for prenatal care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent and clinical context for 76815, guidance on where this service is typically provided, and what to expect in payer coverage considerations.
