Intravenous Antibiotic Therapy and Associated Diagnostic Testing for Lyme Disease

Effective date
Not stated in the notice
Identified
Jun 20, 2026

Summary

Treatment of Lyme disease consists of oral antibiotics except for neuroborreliosis, Lyme carditis and Lyme arthritis. A 2- to 4-week course of IV antibiotics may be considered medically necessary for neuroborreliosis with objective neurologic complications of documented Lyme disease, and a single 2- to 4-week IV course may be considered for Lyme carditis or for the small subset of well-documented Lyme arthritis that is severe enough to need the rapid response of IV antibiotics. IV antibiotic therapy is considered investigational for conditions such as chronic fatigue syndrome or fibromyalgia without objective evidence of Lyme disease, post-Lyme syndrome, and repeat or prolonged courses longer than 4 weeks.

What to do

Action · 11 steps
01Billing team: For IV antibiotic claims for neuroborreliosis, confirm the chart documents objective neurologic complications of documented Lyme disease.
02Serologic documentation requires a positive or indeterminate ELISA and a positive immunoblot by CDC criteria, or clinical findings of erythema migrans in early infection.
03Documented CSF abnormalities must include all of pleocytosis, intrathecal production of B.
04burgdorferi antibodies, and increased protein.
05PCR-based detection of B.
06burgdorferi in CSF may replace serologic documentation when neurologic symptoms have lasted less than 14 days.
07For Lyme carditis, the chart should show positive serologic findings with a high degree of atrioventricular block or a PR interval greater than 0.3 seconds.
08Confirm IV courses are 2 to 4 weeks, since repeat or prolonged IV courses longer than 4 weeks are considered investigational.
09Do not bill IV antibiotics as medically necessary for chronic fatigue syndrome or fibromyalgia without objective clinical or laboratory evidence of Lyme disease, for seronegative Lyme disease without CSF antibodies, for initial therapy in Lyme arthritis without coexisting neurologic symptoms, for cranial nerve palsy without clinical evidence of meningitis, or for post-Lyme syndrome.
10Do not bill repeat PCR testing used to justify IV therapy beyond 1 month, urine PCR, genotyping, stand-alone C6 peptide ELISA, CXCL13, or OspA testing as medically necessary, since the policy considers them investigational.
11BCBSMS makes no payment for services not documented to be medically necessary.
