How Blue Cross Blue Shield of Michigan denies compounded medications (non-glp-1) — bhrt, ldn, ketamine, custom-dose pediatrics — and how to counter it

Where Blue Cross Blue Shield of Michigan pushes back: 1) Compounded ketamine experimental for mental health; 2) Spravato (esketamine) is FDA-approved alternative; 3) Mental-health pharmacy benefit excludes compounded drugs.

Counter-arguments that hold up: Cite Wilkinson Am J Psychiatry 2017 review on oral / sublingual ketamine in treatment-resistant depression; cite Andrade J Clin Psychiatry 2017. Document failed standard antidepressants (SSRIs, SNRIs, augmentation) per STAR*D / Maudsley framework. Spravato (esketamine intranasal) FDA-approved 2019 is the comparator commercial product — when Spravato is unavailable due to access, REMS-prescriber location barrier, cost-share unaffordable, or in-clinic-administration impractical, compounded sublingual / intranasal ketamine is medically necessary. Submit pharmacy 503A + USP 795 compliance + Schedule III handling. Ketamine HCl is on the FDA 503A bulks list Category 1.
