Thread: Ganglion impar block

    Default Ganglion impar block

    AAPC: Back to School
    I need help coding for a ganglion impar block. I am looking at 64520 but am unsure. Is there a better code to use?

    Look at 64505 and 64510. It will also help. But you are under correct series of codes

    Thank You

    The ganglion impar is found anterior to the coccyx and is the only unpair sympathetic ganglion. Commonly it is injected for diagnosis of rectal pain due to tumor, trauma, etc.

    Currently there is no CPT code for either an injection of destruction of the ganglion impar. Per Sept 2007 CPT Assistant: report 64999 for an injection of the ganglion impar.

    Thank You Marvelh for your contribution. Here is the cpt assistant article.

    Surgery: Nervous System
    CPT Assistant September 2007, Volume 17, Issue 9, pages 10-11
    What is the appropriate CPT code to report for a ganglion impar sympathetic block?
    Code 64999, Unlisted procedure, nervous system, should be reported. When reporting an unlisted code to describe a procedure or service, it will be necessary to submit supporting documentation (eg, a procedure report) along with the claim to provide an adequate description of the nature, extent, and need for the procedure and the time, effort, and equipment necessary to provide the service.

    CPT 2009 recommended code 64517 to be reported for this procedure versus an unlisted code 64999. Is this still accurate currently?

    __________________________________________________ _______
    CPT Assistant articles over the years have provided concrete understanding in proper code assignment and compliant billing. With gudiance from the AMA via CPT Assistant or CPT Network, published articles are straight from the source, which provide a better understanding of the codes within the CPT Manual. With changes in healthcare everyday and with such future requirements-- EMR/EHR, E presribing, Quality measures reporting, there is not a reason to make it more difficult than it needs to be. If there is CPT Assistant article that states it is unlisted, until otherwise specified that is considered the most appropriate code to bill. CPT 2009 did not state to use hypogastric plexus block for this procedure but that procedure could be compared in a cover letter for the pricing or requested reimbursement when you bill the insurance company the unlisted code.

    Is 64999 still the only acceptable code for an Impar Ganglion Block?
