Medicare “Cleaning Up” Providers with Tax ID vs. SS Numbers

Medicare is cracking down on providers who do not have their information recorded properly with Medicare. For example, if a provider signed up with Medicare under his/her social security number, but now uses a tax ID# for claims, his/her claims are being rejected by Medicare stating “NPI/Tax ID number not on crosswalk.” Medicare is requiring that your NPI number, your EIN or Tax ID number, and your LBN (Legal Business Name as registered with the IRS) all match up. If you tax id number is registered to John Smith MD but you call your practice Centertown Medical Office, Medicare must have you on file as John Smith MD. Their name for you must match what is on file with the IRS. Also, your NPI number must also match up with the IRS information. So if you are receiving strange rejections from Medicare, or if you have received a letter from CMS stating that your information doesn’t match, you need to straighten it out.

If you don’t have any idea what part is not matching, your best bet is to call your Medicare carrier and verify your information with them. They usually can direct you as to what information is not matching up.
