Health26 Lyme Disease Most Common in the Age Group 51-60 in the Period 2018-2022

Malaise and Fatigue and Soft-Tissue-Related Diagnoses Were Generally More Common in Lyme Disease Patients Than All Patients, according to FAIR Health Study

NEW YORK, Oct. 17, 2023 /PRNewswire/ — In the period 2018-2022, more Lyme disease claim lines were filed for individuals in the 51-60 age group than any other group, according to an infographic based on private insurance claims and released today by FAIR Health.1 Individuals aged 51 to 60 accounted for 23.5 percent of Lyme disease claim lines, compared to 18.8 percent in the next largest age group, 41-50. The remaining age groups studied, with their percentages of Lyme disease claim lines, were 31-40 (14.1 percent), 19-30 (14.0 percent), 61-70 (13.9 percent), 0-18 (11.3 percent) and over 70 (4.3 percent).

These and other findings on this tick-borne, bacterial illness were drawn from the national, independent nonprofit organization FAIR Health’s database of over 42 billion privately billed healthcare claim records, the largest such repository in the nation. Among the other key findings:

  • To identify later diagnoses associated with Lyme disease, FAIR Health examined a statistically significant cohort of individuals from 2018 to 2022, comparing the prevalence of certain diagnoses among Lyme patients to all patients in the cohort. The analysis found that, across all age groups except those over 80, malaise and fatigue and soft-tissue-related diagnoses were more common among Lyme patients than among the total patient population.
  • The prevalence of Lyme disease varies by time of year when comparing rural and urban areas. From 2018 to 2022, claim lines with Lyme disease diagnoses peaked nationally in June and July of each year. During these summer months, rural areas, on average, had a greater share of claim lines associated with Lyme disease diagnoses than urban areas. From November to April, however, claim lines with Lyme disease diagnoses occurred more often in urban than rural areas.
  • In 2018, the states with the greatest proportion of claim lines with Lyme disease diagnoses as a percentage of all diagnoses in the state, from highest to lowest, were New Jersey, North Carolina, Rhode Island, Connecticut and Massachusetts.
  • By contrast, in 2022, the top Lyme disease states, from highest to lowest, were New Jersey, Vermont, Connecticut, Pennsylvania and Rhode Island. North Carolina and Massachusetts dropped off the list, and Vermont and Pennsylvania joined the list. Connecticut rose from fourth to third place, and Rhode Island fell from third to fifth place.

FAIR Health President Robin Gelburd stated, “Lyme disease remains a pressing public health concern. FAIR Health will continue to use its repository of claims data to provide actionable and relevant insights to healthcare stakeholders seeking to better understand this disease.”
