50.1 - Electronic Submission of Claims and Mandatory Assignment
(Rev. 2979, Issued: 06-27-14, Effective: 01-01-12, Implementation: 07-28-14)
Under the DMEPOS Competitive Bidding Program, all claims shall be submitted electronically
using the ASC X12 837 professional claim format except for MSP claims. (NOTE: Claims with
multiple MSP situations may be submitted on a paper claim.) Exceptions to the mandatory
electronic billing requirement granted under the Administrative Simplification Compliance Act
(ASCA) do not apply to DMEPOS Competitive Bidding claims.
All DMEPOS Competitive Bidding Program claims are subject to mandatory assignment.
Mandatory assignment denotes that a supplier shall accept the Medicare payment as payment in
full for their services. The beneficiary’s liability is limited to any applicable deductible plus the
20 percent coinsurance. For additional information concerning mandatory assignment of claims,
see Chapter 1, §30.3.1 of the Medicare Claims Processing Manual.
