Summary & Overview
CPT 76815: Limited Fetal Ultrasound Examination
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. The publication covers benchmarking and utilization patterns, common billing modifiers and claim considerations, and relevant clinical scenarios that differentiate limited from routine or comprehensive fetal ultrasound services.

Billing Code Overview
CPT code 76815 describes a limited ultrasound examination of the fetus. The provider performs a focused assessment of one or more specific fetal parameters rather than a comprehensive fetal survey. The service emphasizes targeted imaging to evaluate discrete clinical questions, such as fetal position, cardiac activity, amniotic fluid assessment, or growth parameters when a full anatomic or detailed fetal study is not required.
-
Service type: Limited fetal ultrasound examination (targeted ultrasound)
-
Typical site of service: Outpatient imaging centers, hospital outpatient departments, and physician offices with ultrasound capability where obstetric or maternal-fetal evaluations are performed.

Clinical & Coding Specifications
Clinical Context
A 28-year-old pregnant patient at 22 weeks' gestation presents to the obstetric ultrasound suite for a focused, limited fetal ultrasound 76815 requested by the maternal–fetal medicine specialist because of a single, specific concern: reduced fetal movement reported by the patient the previous evening. The outpatient visit begins with brief clinical intake documenting last fetal movement, maternal vital signs, and pertinent prenatal history. The sonographer performs a targeted limited fetal exam to assess the identified parameter(s) — for example, fetal presentation, fetal heart activity (cardiac motion and rate), amniotic fluid volume, or placental location — rather than a comprehensive anatomical survey.
The provider documents the specific indication prompting the limited exam, the exact parameters evaluated, ultrasound findings for those parameters, and any immediate clinical interpretation or recommendation. If the imaging identifies an urgent abnormality (absent cardiac activity, significant oligohydramnios, or malpresentation requiring immediate management), the provider communicates results to the ordering clinician and documents the communication and any plan. Typical sites of service include the outpatient obstetrics clinic, hospital-based labor and delivery unit, and freestanding imaging centers that offer obstetric ultrasound.
