Baird analyst Brian Skorney noted Anthem (ANTM) has categorized Sarepta (SRPT) Duchenne muscular dystrophy drug Exondys 51 as "not medically necessary" in a new coverage policy, but he cautions this "does not mean that Anthem is not covering the drug." The analyst explains that the policy means prior authorization requirements may be stricter, but he "highly doubts" that eligible patients will be denied coverage. Skorney, who adds that other large insurers appear to have favorable coverage for the drug, keeps an Outperform rating and $102 price target on Sarepta shares.
