Joint, limb, back, abdominal and bowel pain are the most common types of chronic pain. A study published in The Journal of Pain analyzed treatment data from more than 4.8 million chronic-pain patients with commercial or Medicaid insurance. The researchers found that while the types and frequencies of pain were similar across insurance groups, treatments differed significantly.

Commercially insured patients were more likely to receive restorative and complementary treatments than those with Medicaid. For example, physical therapy was provided to 9 percent of Medicaid-insured patients, compared to 31.1 percent of commercially insured patients. Chiropractic care was accessed by 19.2 percent of Medicaid-insured patients and 38.6 percent of commercially insured patients.

Commercially insured patients also received care more quickly, with wait times from diagnosis to treatment being 50 days shorter for restorative therapy. Medicaid patients were more likely to rely on prescription pain medications, with 81.6 percent having at least one prescription, versus 65.6 percent of commercially insured patients. Commercially insured patients accessed outpatient specialist care more frequently and used multiple non-medication treatments
