CaseWhy Appeals now covers Medicare Part D
CaseWhy Appeals started with Medicare Advantage denials. As of today, it does the same job for Medicare Part D: a prescription drug denied as not on your plan's formulary, requiring prior authorization you weren't told about, or subject to a step-therapy or quantity limit you weren't expecting.
Upload the denial notice and CaseWhy Appeals explains, in plain language, what the actual Part D rule requires, tells you both of your deadlines — the coverage-determination clock and, if you need it, the faster expedited-review clock — and drafts the appeal letter itself, citing the real rule rather than a generic template.
One deliberate difference from the Medicare Advantage product: your case record never has a field for the name of your specific medication — CaseWhy Appeals works from the denial category and reason on your notice instead, and the letter it drafts still cites the exact rule your plan is required to follow. For a typed or pasted notice, the drug's name is stripped out before it's ever sent to the model that writes your explanation, too.
Understanding the denial is free, the same as it's always been. Fighting it is $39 once for a Part D case, after your letter already exists — you see it before you're ever asked to pay.
