What 76813 covers
This obstetric ultrasound measures the fluid-filled space at the back of the fetal neck during first-trimester screening for chromosomal abnormalities. An ultrasound technologist or physician acquires the images, and an interpreting physician—often an obstetrician, radiologist, or maternal-fetal medicine specialist—documents the measurement. The scan may use a transabdominal or transvaginal approach, depending on the clinical circumstances and image quality.
Report 76813 for one fetus or the first fetus in a multiple gestation; report 76814 for each additional gestation when its measurement is performed. Documentation should support the number of fetuses assessed, the nuchal translucency measurement, image acquisition, and the physician’s interpretation. CMS recognizes professional and technical components: bill modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier for the global service. The professional and technical components have separate payment rates.
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.

- 76814Nuchal translucency
- 76813 covers one fetus or the first fetus in a multiple gestation. 76814 covers each additional fetus whose NT is measured.
- 76811Obstetric ultrasound
- 76811 is for a detailed fetal anatomic examination. 76813 is for the first-trimester nuchal translucency measurement.
76813 billing questions
How does 76813 differ from 76801?
76813 reports the first-trimester nuchal translucency measurement. 76801 is for a first-trimester obstetric ultrasound examination, rather than the specific NT measurement.
How is 76813 used for a multiple gestation?
Report 76813 for the first fetus assessed and 76814 for each additional fetus with a separately performed NT measurement.
Can the professional and technical services be billed separately?
Yes. Use modifier 26 for the physician’s interpretation or modifier TC for the equipment and staff; billing without either modifier represents the global service.
What documentation supports 76813?
The record should identify the fetus assessed and include the NT measurement, supporting images, and the interpreting physician’s findings.
Does 76813 represent a complete first-trimester anatomy survey?
No. It represents the nuchal translucency measurement; use 76801 when a complete first-trimester obstetric ultrasound examination is performed and documented.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
