Coding Pain Management ServicesNotes/Comments/QuestionsInjections Questions to ask:When reporting spinal injections keep these key questions inmind and it will help you determine which series of codes touse.What is the approach? Epidural, transforaminal, facet What is being injected? Anesthetic, steroid, contrast, neurolytic agent What regions are treated? Regions: cervical, thoracic, lumbar, sacral How many levels are treated? Is it a unilateral or a bilateral injection? One or more than one level31Injections Epidural injectionsThe approach for an epidural injection is directly into theepidural space between vertebrae. The purpose is to relievecervical or neck pain; thoracic or midback pain; lumbar or lowback pain. Transforaminal injectionsThe approach for a transforaminal injection is by way of theintervertebral foramen. There are two foramen for eachvertebra on opposite sides of the spine. The needle is insertedto gain access to the epidural space and nerve root. Facet joint or facet joint nerve injectionsThe approach for facet injections are by way of theintravertebral facets. Each vertebra has four facets.Injections are performed to block the pain signals from thefacet joint of the spine and associated nerves to the brain.AHIMA 2008 Audio Seminar SeriesCPT Codes Copyright 2007 by AMA.

Coding Pain Management ServicesNotes/Comments/QuestionsDestruction by Neurolytic Agent Trigeminal rhizotomy may be performed byradiofrequency ablation or by neurolytics.Trigeminal ablations are performed to treattrigeminal neuralgia or tic douloureux. This is acondition of the fifth cranial nerve thought to because by compressive venous or arterial loops inthe face. The intense pain caused by this conditionis often triggered by activities such as chewing orteeth brushing. It is sometimes referred to as the“suicide disease” because patients are driven totake their own life due to intense pain and failureto obtain effective treatment.47Destruction by Neurolytic Agent Destruction by neurolytic agent trigeminalnerve; 64600supraorbital, infraorbital mental orinferior alveolar 64605second and third division at theforamen ovale 64610second and third division at theforamen ovale with radiologicmonitoring Report modifier 50 for bilateral injections at thesame level48AHIMA 2008 Audio Seminar SeriesCPT Codes Copyright 2007 by AMA.
