What 72220 covers
This examination produces radiographic images focused on the sacrum and coccyx, with at least two views. It is commonly ordered for localized tailbone pain, injury, or concern about an abnormality in these bones. A radiologic technologist typically obtains the images in an outpatient imaging department, hospital, or office equipped for X-ray; a physician, often a radiologist, interprets them and documents the findings.
Report 72220 when the ordered study targets the sacrum and coccyx, rather than the sacroiliac joints or lumbar spine. The record should support the reason for imaging and identify the requested anatomy; the image set and interpretation report support the service performed. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and billing without either modifier represents the global service.

72220 billing questions
When should 72220 be chosen instead of a sacroiliac joint X-ray?
Use 72220 when the examination targets the sacrum and coccyx. Sacroiliac joint studies are reported with 72200 or 72202, depending on the views.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 reports the physician's interpretation, and modifier TC reports the technical portion. Without either modifier, the claim represents the global service.
What documentation supports this code?
The record should show the clinical reason for imaging and the sacrum and coccyx as the requested anatomy. The images and a physician's interpretation report support the service.
Does the code include both image acquisition and interpretation?
The global service includes both portions. When the portions are furnished and billed separately, use modifier 26 for interpretation or modifier TC for the technical service.
How is 72220 distinguished from a lumbar spine X-ray?
Choose 72220 for imaging centered on the sacrum and coccyx. Use a lumbar spine code when the study is directed at the lumbar vertebrae.
