Thrombectomy and Stent In the Same Procedure

Leorah Posted Sun 01st of October, 2017 14:13:37 PM
Our doctors performed a Mechanical thrombectomy (61645) in the right common carotid artery. After performing the procedure the doctors looked up further to the internal carotid artery and decided that a carotid stent was needed (37215) to keep proper blood flow. Our doctors have said that we can code both the 61645 and the 37215 because the stent was much further up in the brain and in a different area. If that is the case then I am not sure which ICD diagnosis codes I should use. I used I63.311 for the thrombectomy. What should I use for the stent? If I show it is on the same side will the insurance deny the 37215 code?

  • The ICD part is not very much clear as per documentation provided above. If you go by SuperCoder index and search for thrombosis, then it will lead to ICD I65.2x series {Occlusion and stenosis of carotid artery} which seems to be the correct ICD as per above scenario. You need to refer your operative report to get an exactly correct ICD and also just for reference purposes, you can go through CPT to ICD crosswalk options available in SuperCoder.
  • As per NCCI guidelines, both CPTs 37215 and 61645 can be reported at the same session by adding modifier-59 with CPT-61645 in order to indicate the distinctness of the procedure.
