Medicare Provider Enrollment and PECOS Applications.
CMS-855 applications, PECOS management, reassignments and group additions prepared correctly the first time — with follow-up through your MAC until the approval letter arrives.
Common Medicare enrollment failures
Wrong application type
Filing an 855I when the situation needs an 855B or 855R restarts the process from zero.
Development letters
MAC requests for missing information carry short response deadlines; a missed reply means rejection.
Reassignment errors
Incorrect reassignment of benefits sends payments to the wrong entity or blocks them entirely.
Effective date surprises
Retrospective billing rules are narrow; misunderstanding them creates uncollectible claims.
