May 23, 2008 is Fast Approaching! Are You Using Your Registered NPI Correctly?

Claims submitted incorrectly and without a registered NPI on or after May 23, 2008, will reject. You must register your NPI with IBC prior to submitting claims. Register your NPI online with IBC now.

Each claim must pass an NPI check-digit validation to ensure that it has a valid NPI. To date, many claims are not passing this check-digit validation. Claims that fail the check-digit validation after May 23, 2008, will reject. The most common reasons why claims are not passing the NPI check-digit validation are:

• the wrong provider identifier is entered in an NPI field;
• the NPI is entered incorrectly;
• the number entered is not a valid NPI.

If you are currently submitting claims with an NPI and a 10-digit legacy identifier, we have been able to accept your claims into our system consistent with our contingency plan. However, as of May 23, 2008, in accordance with the CMS mandate, providers must use the NPI as the primary identifier on the claim, and IBC will reject claims with invalid NPIs on or after this date.
