Idaho has the longest list
If you see UHC Community Plan patients in Idaho, more tests are limited or not paid starting November 1, 2026 (fecal calprotectin, bone turnover markers), December 1, 2026 (gut dysbiosis stool testing, some autoimmune/ANA panels, Lyme) and January 1, 2027 (pancreatitis enzymes, with lipase limited to once a week; IBD serologic markers; immune cell function assays; intracellular micronutrient testing; certain onychomycosis tests; ST2; homocysteine).
How does this affect my practice?
More lab denials if your order sets or standing orders don't match the new limits.
Diagnosis codes matter more than ever. Many of these tests are paid only when the claim carries a qualifying diagnosis.
Frequency tracking becomes your job. A B12 test repeated after 2 months, or a fibrosis panel after 4, can be denied.
Patient trust. Medicaid patients usually can't be billed for denied services. Check your state's Medicaid rules before sending any bill. Mostly, the denial just becomes lost revenue.
What should I do now?
