Below CPT 72275 for Medicare is found in addendum BB for ASCs. Addendum BB are services that are considered packaged and no separate payment is made.
CPT 72275 has a status indicator on the facility side for Medicare as N1
N1 Packaged service/item; no separate payment made.
Additionally below I copy and pasted the state operations manual describing the ASC as providing surgical services and certain services are considered ancillary. Procedures such as discograms or myelograms are not covered in ASCs for Medicare because they have a primary diagnostic purpose.
The concern that you would want to review is the procedure actually for the purpose of diagnostic epidurogram or is it more of the contrast is being injected with limited notation of the structures, but the primary purpose is therapeutic. Typically CPT 72275 is not going to be covered and the reason for the epidural is therapeutic.

Exclusive Provision of Limited Surgical Services
The ASC must offer only surgical services. Separate ancillary services that are integral to the surgical services, i.e., those furnished immediately before, during or immediately after a surgical procedure, may be provided. The ASC may not, however, offer services unrelated to the surgeries it performs.
What constitutes ?surgery??
For the purposes of determining compliance with the ASC definition, CMS relies, with minor modification, upon the definition of surgery developed by the American College of Surgeons (
www.facs.org/fellows_info/statements/st-11.html.) Accordingly, the following definition is used to determine whether or not a procedure constitutes surgery:
Surgery is performed for the purpose of structurally altering the human body by the incision or destruction of tissues and is part of the practice of medicine. Surgery also is the diagnostic or therapeutic treatment of conditions or disease processes by any instruments causing localized alteration or transposition of live human tissue which include lasers, ultrasound, ionizing radiation, scalpels, probes, and needles. The tissue can be cut, burned, vaporized, frozen, sutured, probed, or manipulated by closed reductions for major dislocations or fractures, or otherwise altered by mechanical, thermal, light-based, electromagnetic, or chemical means. Injection of diagnostic or therapeutic substances into body cavities, internal organs, joints, sensory organs, and the central nervous system, is also considered to be surgery. (This does not include the administration by nursing personnel of some injections, subcutaneous, intramuscular, and intravenous, when ordered by a physician.) All of these surgical procedures are invasive, including those that are performed with lasers, and the risks of any surgical procedure are not eliminated by using a light knife or laser in place of a metal knife, or scalpel.
