Effective Jan. 1, 2003, the National Correct Coding Initiative started bundling CPT 72275 into the epidural codes 62310 and 62311. Append modifier -59 (Distinct procedural service) to 72275 only if you perform epidurography and an epidural injection during separate sessions on the same date of service.
Remember that the physician must provide a formal radiological report when reporting the epidurography radiological supervision and interpretation code.
