We have recently started to bill out for pain pump refills and I'm not familiar with J codes. Right now for one specific patient we are needing to bill out for Bupivacaine PF 10MG/ML and Hydromorphone PF 1MG/ ML. I have been told by Iowa Medicaid, which is the insurance the patient has, that J3490 is a dump code, billable with documentation. I have also been advised to use J7799, also a dump code, billable with documentation. I'm not sure which direction to go in. If any one has any knowledge of what direction to go in for pain pump refills I would greatly appreciate it.
