Capture Bilateral 62311
PDF
Question: When I use CPT 62311 how do I capture the "bilateral" portion? The descriptor states "single" injection, but I have a "bilateral epidural space" in the physician dictation. I know that this code does not allow for modifier -50 (Bilateral procedure), and when I tried billing it with two units, I received a denial. Should I use 64483 instead since it allows for modifier -50? Answer: CPT does not consider interlaminar epidural injections to be unilateral procedures. The injection includes a moderate amount of medication that spreads throughout the whole epidural space, meaning both sides. However, that statement doesn't always hold true. You must have good documentation of the problems the physician encountered during the spread of contrast for these scenarios. If you do, you can add modifier -59 (Distinct procedural service), because the physician performed two procedures with supporting medical necessity. This modifier overrides the National Correct Coding Initiative edit.

A few patients anatomically have an epidural septum that prevents the spread of contrast and, likewise, the medication. Also, the patient could have a large herniation that impinges on the anterior epidural space. Then the physician may be forced to perform a second procedure in an attempt to get the anesthetic/steroid to the contralateral side. Many times the second injection is transforaminal and not interlaminar, so you should look at two codes:
However, you may encounter difficulty when the physician provides two interlaminar injections at the same level and setting. For this rare instance, your supporting documentation must hit the "awesome" category, because most payers will not process a second interlaminar injection. You can always appeal the denial with a letter requesting review by a physician of a similar specialty and a strong letter of medical necessity by your physician.
