What 76818 covers
This service combines real-time ultrasound assessment of fetal breathing, movement, tone, and amniotic fluid with a nonstress test (NST). An obstetric sonographer or other qualified imaging staff may acquire the ultrasound images, while the interpreting physician or qualified practitioner evaluates and documents the findings. The NST records fetal heart-rate response, typically in an obstetric imaging or fetal surveillance setting when a biophysical profile is ordered with heart-rate testing.
Report 76818 when the documented assessment includes both the ultrasound biophysical profile and NST; use 76819 when the profile is performed without NST. The record should support the fetal assessment, ultrasound findings, NST results, and interpretation. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. Reporting without either modifier represents the global service.

76818 billing questions
How is 76818 different from 76819?
76818 includes an NST along with the ultrasound biophysical profile. Use 76819 when the profile is performed without an NST.
Can the NST also be reported as 59025?
The NST is part of 76818 when it is performed as the NST component of that biophysical profile. Do not separately report 59025 for that same NST service.
What do modifiers 26 and TC represent?
Modifier 26 identifies the professional interpretation. Modifier TC identifies the technical service, including equipment and staff; without either modifier, the claim represents the global service.
What documentation supports 76818?
Document the ultrasound biophysical findings, amniotic fluid assessment, NST results, and the interpreting professional’s conclusion. The record should show that both ultrasound assessment and NST were performed.
Is 76818 reported per fetus or by time?
The service is a fetal assessment, not a timed service. Document which fetus or fetuses were assessed and the work performed for each.
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.
