CMS Pub. 100-04, ch. 19, § 90

NOTE: CMS seeks to reduce burden and modernize processes to ensure a reduction in

improper payments and an increase in customer satisfaction. The Certificate of Medical

Necessity (CMN) form and DME Information Form (DIF) were originally required to

help document the medical necessity and other coverage criteria for selected Durable

Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) items. In the past, a

supplier received a signed CMN from the treating physician or created and signed a DIF

to submit with the claim. Due to improvements in claims processing and medical records

management, the information found on CMNs or DIFs is available either on the claim or

in the medical record and is redundant. Therefore, to reduce burden and increase

customer satisfaction, providers and suppliers no longer need to submit these forms for

services rendered after January 1, 2023.

• For claims with dates of service on or after January 1, 2023 – providers and

suppliers no longer need to submit CMNs or DIFs with claims. Due to electronic

filing requirements, claims received with these forms attached will be rejected

and returned to the provider or supplier.

• F or claims with dates of service prior to January 1, 2023 – processes will not

change and if the CMN or DIF is required, it will still need to be submitted with

the claim, or be on file with a previous claim.

This statement applies throughout the Program Integrity Manual wherever CMNs and

DIFs are mentioned.

The DME MACs process claims for items of DMEPOS for use in the beneficiary’s

home. Beginning January 1, 2005, Medicare Part B makes payment for medically

necessary items of DME, prosthetics, orthotics, and supplies to IHS suppliers that furnish

DME for use in the beneficiary’s home. See Pub. 100-02, Medicare Benefit Policy

Manual, Chapter 15, §110 for more information on this benefit.

Note that the DME MACs make payment for DMEPOS only in cases where the

beneficiary medically needs the equipment in his or her home. Items provided during an

inpatient hospital or SNF stay are included in the payment made to the hospital or SNF,

with certain exceptions. (See Chapter 6, §20.3 of Pub. 100-04, Medicare Claims

Processing Manual for exceptions to SNF consolidated billing, and Chapter 20, §110.3

for exceptions to DMEPOS provided for fitting and training prior to an inpatient

discharge.) More information regarding when items of DMEPOS are billed to a DME

MAC or to an A/B MAC (A) is outlined below.

For more information on jurisdiction, payment policy, and claims processing rules for

DMEPOS, see Chapters 1 (for general information of submitting Medicare claims), 17

(for information specific to drugs paid by the DME MACs), and 20 (for information

specific to DMEPOS items and services) of Pub. 100-04, Medicare Claims Processing

Manual.
