Epidemiology of Systemic Sclerosis in a Large US Managed Care Population

The Journal of Rheumatology, 03/05/2012

Furst DE et al. – This analysis suggests a higher incidence and lower prevalence of systemic sclerosis (SSc) in this managed care organization (MCO) than those previously reported for the United States.


  • Subjects with claims–based evidence of SSc (ICD–9–CM code 710.1x) were identified from a health plan database.
  • Incidence and prevalence for the period 2003–2008 were calculated.


  • The overall age– and sex–adjusted incidence rate (2003–2008) for SSc was 5.6 cases per 100,000 person–years.
  • The annual prevalence of SSc ranged from 13.5 in 2003 to 18.4 (per 100,000) in 2008.
