The Limited Income NET (LI NET) Program is designed to eliminate gaps in coverage for low-income individuals transitioning to Medicare Part D drug coverage.
Point-of-sale prescription drug coverage
The LI NET Program ensures that individuals with Medicare’s low-income subsidy (LIS), or Extra Help, who are not yet enrolled in a Part D prescription drug plan, are still able to obtain immediate prescription drug coverage. If an individual is later determined to be ineligible because he or she does not receive the LIS, the individual will be financially responsible for claims already paid on his or her behalf.
Retroactive prescription drug coverage
The LI NET Program provides retroactive coverage for new dual eligibles (those individuals who are eligible for both Medicare and Medicaid or Medicare and Supplemental Security Income [SSI] from the Social Security Administration). Medicare automatically enrolls these individuals into the LI NET Program for eligible periods with an effective date retroactive to the start of their full-benefit dual-eligible status. Enrollment in the LI NET Program is temporary until Medicare enrolls these individuals in a standard Medicare Part D plan for the future.

The enrollment form should be completed when information such as the beneficiary’s low-income subsidy (LIS) status is not visible in Medicare’s systems and it is preventing claims from processing at the point of sale. Best available evidence (BAE) will need to be provided to prove the beneficiary’s eligibility for LIS, Medicaid or Supplemental Security Income (SSI).
