Private insurance claims with a diagnosis of Lyme disease have soared in the U.S. over the past decade, according to a new report by FAIR Health, a nonprofit that tracks healthcare costs and insurance trends.
Lyme disease is a bacterial illness spread by ticks. It can also lead to other chronic pain conditions such as joint and back pain, chronic fatigue, fibromyalgia and neuropathy.
Fair Health analyzed a database of 23 billion private insurance claims from 2007 to 2016, and found that claims with a diagnosis of Lyme disease increased by 185 percent in rural areas and 40 percent in urban areas.
A recent CDC study also found the number of Lyme disease cases increasing, with nearly 40,000 confirmed and probable cases in 2015.
"Lyme disease is growing as a public health concern,” said FAIR Health President Robin Gelburd
Although Lyme disease historically has been concentrated in the Northeast and upper Midwest, the FAIR Health study suggests that it is spreading geographically. In 2007, insurance claims with diagnoses of Lyme disease were highest in New Jersey, Rhode Island, Connecticut, Massachusetts and New York.
By 2016, the top states were Rhode Island, New Jersey, Connecticut, North Carolina and New York -- with the emergence of North Carolina suggesting significant expansion to a new region.
Summer is the peak season for Lyme disease, with insurance claims more common in rural than in urban settings, according to the FAIR Health report. In the winter and early spring (December through April), claims involving Lyme disease were reported more often in urban than rural settings.
Age is also a differing factor in rural and urban environments. In rural settings, claims with Lyme disease diagnoses were more common for middle-aged and older people. Patients aged 41 years and older accounted for nearly two-thirds of the rural diagnoses. In urban populations, younger individuals with Lyme disease accounted for a higher percentage of claims.
Lyme disease is usually treated with antibiotics, but some patients experience complications that lead to Lyme disease syndrome (PTLDS), with long-term symptoms such as fatigue, muscle and joint pain and cognitive issues. Autoimmune diseases have also been associated with chronic Lyme disease.
Left untreated, Lyme disease can lead to serious chronic conditions, as Sarah Elizabeth Hirschle shared with us recently.
For patients with a Lyme disease diagnosis, FAIR Health reported the most common subsequent diagnoses were:
- Joint pain (dorsalgia, low back pain, hip and knee pain)
- Chronic fatigue
- Soft tissue disorders (myalgia, neuralgia, fibromyalgia)
Early symptoms of Lyme disease include fever, chills, headaches, fatigue, muscle and joint aches, and swollen lymph nodes. A delayed rash often appears at the site of the tick bite. The rash grows in size and sometimes resembles a bulls-eye.
