Just like virtually all code sets, mammography codes saw several changes with the beginning of the 2018 calendar year. These codes, used to describe a variety of breast imaging services, have seen numerous changes in the recent past, including last year. For 2017, the CPT codebook removed codes 77051-77057 and replaced them with a set of three new codes. The Centers for Medicare and Medicaid Services (CMS), however, did not accept these replacement CPT codes and instead mandated the use of several G codes in their place. Thankfully, the 2018 update removed these G codes and brought everyone back to the same page.
The G codes that were deleted beginning January 1st are:
- G0202: screening mammography, bilateral (2-view study of each breast), including computer aided detection (CAD) when performed
- G0204: diagnostic mammography, including CAD when performed, bilateral
- G0206: diagnostic mammography, including CAD when performed, unilateral
In their place, the following 2017 CPT codes were formally adopted by CMS:
- 77067: screening mammography, bilateral (2-view study of each breast), including CAD when performed
- 77066: diagnostic mammography, including CAD when performed, bilateral
- 77065: diagnostic mammography, including CAD when performed, unilateral
Additionally, the CPT codes 76706 (a replacement for G0389) also saw some changes. Though officially implemented back in January 2017, the new year changed the Type of Service (TOS) from 5 to 4, although the coinsurance and deductible for this service will continue to be waived.
All coders who work with practices that provides these types of services should be sure to review all of these coding updates and apply them to any claims in 2018. In addition, it is a good idea to monitor further CMS updates throughout the year in case additional changes are made. By always staying up to date with the latest codes and compliance trends, practices can make sure that they provide the greatest level of care possible.
