G8806 Pregnancy Location Ultrasound HCPCS Reimbursement

HCPCS Level II code G8806 denotes the performance of a trans-abdominal or trans-vaginal ultrasound with documentation of pregnancy location. This code is used when imaging is performed specifically to identify and record whether a pregnancy is located within the uterus or is extrauterine. Nationally, accurate use of this code supports clinical decision-making in early pregnancy care and contributes to tracking imaging utilization for pregnancy location assessment.

Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the service, typical sites of service, and the common modifiers associated with billing for this type of ultrasound. The publication outlines benchmarks and coding considerations relevant to payers named above, highlights common billing practice patterns, and summarizes policy or reimbursement updates when available. Clinical context emphasizes the role of trans-abdominal and trans-vaginal approaches in determining pregnancy location and the implications for patient management. If specific coding crosswalks, ICD-10 pairings, or taxonomy entries are not provided in the input, those items are noted as not available.

Billing Code Overview

HCPCS Level II code G8806 describes the performance of trans-abdominal or trans-vaginal ultrasound with documentation of pregnancy location. The service reflects imaging performed to determine and record whether a pregnancy is intrauterine or extrauterine (e.g., ectopic) using either a trans-abdominal or trans-vaginal approach.

Service type: Diagnostic obstetric ultrasound for pregnancy location determination
Typical site of service: Outpatient imaging centers, hospital outpatient departments, and ambulatory care clinics where ultrasound imaging is performed

Clinical Context

A 28-year-old pregnant patient presents to the outpatient obstetric ultrasound suite with pelvic pain and possible early pregnancy. The clinician orders a transabdominal and, if necessary, transvaginal ultrasound to document intrauterine pregnancy location and to exclude ectopic pregnancy. The sonographer performs a transabdominal scan first; if visualization is limited or more detail is required, a transvaginal scan is performed during the same encounter. Images and measurements (gestational sac, yolk sac, fetal pole, cardiac activity if present) are documented in the report along with the anatomic location of the pregnancy (intrauterine, interstitial, cornual, cesarean scar, or adnexal). Findings are reviewed with the ordering clinician; results are placed in the medical record and used to guide next steps such as routine prenatal care, serial beta-hCG monitoring, or urgent gynecologic referral for suspected ectopic pregnancy.
