Question: Our provider blocked a lumbar dural tear with a single piece of gelfoam. Would you code this at 62273? Wyoming Subscriber Answer: No, code 62273 (Injection, epidural, of blood or clot patch) is not an appropriate choice for application of a piece of gelfoam to seal over an epidural tear. That’s because the physician typically uses an open surgical approach to insert the gelfoam as a dural repair rather than injection as indicated in the 62273 code descriptor. If you’re coding for an open approach to dural repair, options include: If the physician completes the dural repair during another spinal procedure, it typically is included as part of the surgical procedure and is not separately billable.
