Following a 2015 Congressional directive, CMS is abandoning its Social Security based Medicare ID for a new randomly generated one. The new card will be hitting beneficiary’s mailboxes in April with everyone covered by a year later.
The old ID is a SSN plus one letter. The letter says if you are a beneficiary, child, widow, etc. The new will have both letters and numbers. It is wholly random and drops the coding for beneficiary, etc. Fortunately, it will exclude S, L, O, I, B and Z, which can look like numbers. You can see the new ID’s details here.
Claimants will have until 2020 to adopt the new IDs, but that’s not the half of it. For the HIT world, this means many difficult, expensive and time consuming changes. CMS sees this as a change in how it tracks claims. However, its impact may make HIT managers wish for the calm and quiet days of Y2K. That’s because adopting the new number for claims is just the start. Their systems use the Medicare ID as a key field for just about everything they do involving Medicare. This means they’ll not only have to cross walk to the new number, but also their systems will have to look back at what was done under the old.
Ideally, beneficiaries will only have to know their new number. Realistically, every practice they see over the next several years will want both IDs. This will add one more iteration to patient matching, which is daunting enough.
With MACRA Congress made a strong case for Medicare no longer relying on SSNs for both privacy and security reasons. Where it failed was seeing it only as a CMS problem and not as an HIT problem with many twists and turns.
