CMS 1500 Claim Form Transition

Currently, Colorado Medicaid providers submit professional claims electronically or via the Colorado 1500 (CO-1500) paper claim form. Effective December 1, 2014, the CO-1500 paper claim form will be replaced by the current CMS 1500 paper claim form (rev. 02-12).  Per federal mandate, the Department is required to institute ICD-10 diagnosis and procedure code sets throughout its systems and business processes for claims with dates of service on or after October 1, 2015. In preparation for this implementation, the Department is transitioning all professional paper claim submission to the CMS 1500 claim form.
