Professional and facility claims began rejecting on March 1, 2017, when billing and rendering or attending taxonomy is not properly reported. When providers submit NPI(s) anywhere on a claim, the corresponding taxonomy must also be submitted. When billing and rendering/attending NPI is included on a claim that may be coordinated with UCare coverage, the corresponding taxonomy must be included in order for UCare to process the claim. Claims that are coordinated with UCare coverage and do not have taxonomy reported, when applicable, will be rejected. When a claim is rejected due to taxonomy not being properly reported, a provider may see the rejection or error category of A6 (The claim/encounter is missing the information specified in the status details and has been rejected) and error code 145 (Entity’s specialty/taxonomy code) on their 277 CA, rejection report from their clearinghouse. To avoid payment delays on these claims, add taxonomy to the claim and resubmit it to UCare.
