What 78431 covers
This examination uses PET to assess myocardial perfusion in separate rest and stress acquisitions, with a concurrently acquired CT used for attenuation correction. Stress may be induced by exercise or medication. Nuclear medicine or cardiology imaging teams perform the technical study, and a qualified practitioner interprets the images. This protocol distinguishes the code from a single-study PET examination and from SPECT myocardial perfusion imaging.
Medicare assigns physician fee schedule status C (carrier priced): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The service has professional and technical portions: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no modifier reports the global service. Report the code for the rest-and-stress PET myocardial perfusion examination with CT.

How to choose
- 78429Cardiac PETSingle metabolic study with CT
- 78429 is a single PET study with metabolic evaluation at rest or stress. This code covers rest-and-stress PET myocardial perfusion imaging.
- 78430Myocardial PETRest and stress with CT
- Both codes describe rest-and-stress PET myocardial perfusion imaging with CT. 78431 specifies a concurrently acquired CT for attenuation correction.
- 78451Cardiac SPECTSingle rest or stress study
- 78451 is a single-study SPECT myocardial perfusion examination. This code is a rest-and-stress PET examination with concurrently acquired CT.
- 78452Nuclear stress testSPECT, multiple perfusion studies
- 78452 is multiple-study SPECT myocardial perfusion imaging. This code is the PET rest-and-stress examination with concurrently acquired CT.
78431 billing questions
When should this code be used instead of a SPECT cardiac study?
Use this code for rest-and-stress myocardial perfusion imaging performed with PET and concurrently acquired CT. SPECT myocardial perfusion studies are reported with codes such as 78451 or 78452, depending on the study.
Does this code include both rest and stress imaging?
Yes. It represents PET myocardial perfusion imaging at rest and under exercise or pharmacologic stress, with concurrently acquired CT for attenuation correction.
How should the professional and technical portions be reported?
Append modifier 26 for the professional interpretation or modifier TC for the technical portion. Report the global service without either modifier.
Does Medicare publish a national payment for this code?
No. Its physician fee schedule status is C, meaning the Medicare Administrative Contractor sets payment for each claim.
How does this differ from 78429?
Code 78429 describes a single PET study with metabolic evaluation at rest or stress. This code represents PET myocardial perfusion imaging at both rest and stress.
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.
