2013 CMS Updates in Molecular Pathology CPT Coding

Effective January 1st 2013. The AMA is implementing over 100 new CPT codes for molecular pathology.  These codes will replace the current stacking codes (83890 – 83914). We are providing the new 2013 codes for informational purposes only as guidance to assist clients with billing.

Pricing will remain unchanged, unless a new service line was created. We strongly recommend that clients confirm CPT codes with their Medicare Administrative Contractor or other payers. We will continue to monitor the industry’s use of the new CPT codes and encourage the AMA and CMS to expand the number of genes specified in the codes. Please contact us with any questions or concerns so we may ensure an efficient and successful transition. 

For the crosswalk of Molecular Pathology CPT codes for 2013, please refer to the CPT Code List. Contact the laboratory at 918-502-1721 or Lynne Whetsell at for pricing information.
