California-Specific Requirements

Medicare Part B enrollment in California is administered by Noridian Healthcare Solutions, the Medicare Administrative Contractor (MAC) for Jurisdiction E, which covers California, Nevada, Hawaii, American Samoa, Guam, and the Northern Mariana Islands. Providers enroll through PECOS using the appropriate CMS form: 855I for individual practitioners, 855B for clinics and group practices, 855R for reassignment of benefits to a group, or 855A for institutional providers. Standard PECOS processing is 45-65 days when the application is clean. California-specific items: Medical Board of California (or allied health board) license verification, retroactive billing limited to 30 days before the enrollment effective date per Medicare rules, and California Medicare Advantage plans (such as CalOptima in Orange County) require separate enrollment with each MA organization. Revalidation required every 5 years per the standard CMS revalidation schedule.
