fili123, I'm currently investigating Forteo/Teriparatide/Tymlos costs for Medicare Part D plans in my area (New England). Both Forteo & Tymlos are brand drugs and under 2024 Part D drug changes (thanks to the Inflation Reduction Act) actually cost approximately $3-3500 for the full year. The costs fall in the first 3 months (Jan-Mar) then there is no monthly cost Apr-Dec.

Teriparatide (generic Forteo) actually costs more, approximately 7-8000 your out-of-pocket for the full year. If understand the medicare drug changes correctly, generic drugs are less cost overall, but spread over all 12 months. It's weird right? We're all conditioned to go to generic drugs for cost savings.

For more information for your area go to Medicare.gov.

Learn more about coverage phases.
What you pay for drugs in a year depends on what coverage phase you’re in. Once you meet your “deductible,” a drug’s cost could vary in each coverage phase. You’ll start a new coverage phase once your spending for drugs has reached a certain amount.

Cost after deductible (also called "initial coverage")
Cost after deductible (also called "initial coverage") - You’ll pay a percentage of the plan’s cost for covered drugs. Once you and your plan spend $5,030 combined on drugs (including deductible), you’re in the coverage gap.

Coverage gap (also called "donut hole")
Coverage gap (also called "donut hole") - You’re in this phase if you and your plan spend $5,030 on drugs. During this phase, your plan doesn’t pay for your drugs. You’ll pay no more than 25% of the cost for brand-name drugs and generic drugs until you spend $8,000.

Cost after coverage gap (also called "catastrophic coverage")
Cost after coverage gap (also called "catastrophic coverage") - You’ll reach this phase if your drug costs reach $8,000 during the year (this includes certain payments made by other people or entities on your behalf, including Medicare’s Extra Help program). You won’t have to pay a copayment or coinsurance for covered Part D drugs for the rest of the calendar year.
