Disaster/Emergency-Related Claims

(Rev. 2999, Issued; 07-25-14, Effective: 01-01-12, Implementation: 08-25-14)

In order to facilitate claims processing and track services and items provided to

beneficiaries during disaster/emergency situations, a modifier and condition code have

been established for providers to use on disaster/emergency related claims. The modifier

and condition code have been in effect since August 21, 2005. The codes are effective

for dates of service on and after August 21, 2005. The modifier and/or condition code

can be used by providers submitting claims for beneficiaries who are emergency patients

in any part of the country.

The DR Condition Code: The title of the DR condition code is “disaster related” and its

definition requires it to be “used to identify claims that are or may be impacted by

specific payer/health plan policies related to a national or regional disaster.” The DR

condition code is used only for institutional billing, i.e., claims submitted by providers

using the ASC X12 837 institutional claim format or on an institutional paper claim Form

CMS-1450. In previous emergencies, use of the DR condition code has been

discretionary with the billing provider or supplier. It no longer may be used at the

provider or supplier’s discretion. Use of the DR condition code will be mandatory for any

claim for which Medicare payment is conditioned on the presence of a “formal waiver,”

as defined below. The DR condition code also may be required for any type of claim for

which, at the A/B MAC (A)’s or (HHH)’s discretion or as directed by CMS in a

particular disaster or emergency, the use of the DR condition code is needed to efficiently

and effectively process claims or to otherwise administer the Medicare fee-for-service

program.

The CR Modifier: Both the short and long descriptors of the CR modifier are

“catastrophe/disaster related.” The CR modifier is used in relation to Part B items and

services for both institutional and non-institutional billing. Non-institutional billing, i.e.,

claims submitted by “physicians and other suppliers”, are submitted either using the ASC

X12 837 professional claim format or on a professional paper claim Form CMS-1500 or,

for pharmacies, in the NCPDP format. In previous emergencies, use of the CR modifier

has been discretionary with the billing provider or supplier. It no longer may be used at

the provider or supplier’s discretion. Use of the CR modifier will be mandatory for

applicable HCPCS codes on any claim for which Medicare Part B payment is conditioned

on the presence of a “formal waiver,” as defined below. The CR modifier also may be

required for any HCPCS code for which, at the A/B MAC (A)’s, (B)’s, or (HHH)’s or

DME MAC’s discretion or as directed by CMS in a particular disaster or emergency, the

use of the CR modifier is needed to efficiently and effectively process claims or to

otherwise administer the Medicare fee-for-service program.

Formal Waivers: A “formal waiver” is a waiver of a program requirement that otherwise

would apply by statute or regulation. There are two types of formal waivers. One type is

a temporary waiver or modification of a requirement under the authority described in

§1135 of the Social Security Act (the Act). Although Medicare payment rules

themselves are not waivable under this statutory provision, the waiver authority under

§1135 may permit Medicare payment in a circumstance where such payment would

otherwise be barred because of noncompliance with the requirement being waived or

modified. The second type of formal waiver is a waiver based on a provision of Title

XVIII of the Act or its implementing regulations. The most commonly employed waiver

in this latter category is the waiver of the “3-day qualifying hospital stay” requirement

that is a precondition for Medicare payment for skilled nursing facility services. This

requirement may be waived under §1812(f) of the Act.

Several conditions must be met for a §1135 waiver to be implemented. First, the

President must declare an emergency or disaster under the National Emergencies Act or

the Robert T. Stafford Disaster Relief and Emergency Assistance Act. Such a declaration

will specify both an effective date and the geographic area(s) covered by the declaration.

Second, the Secretary of the Department of Health and Human Services must declare -

under §319 of the Public Health Service Act - that a public health emergency exists

within some or all of the areas covered by the Presidential declaration. Third, the

Secretary must authorize the waiver of one or more requirements specified in §1135 of

the Act. Fourth, the Secretary or the Administrator of CMS must determine which

Medicare program requirements, if any, may be waived or modified under the Secretary’s

authorization and whether specific conditions within the geographic area(s) specified by

the Secretary’s declaration warrant waiver or modification of one or more requirements

of Title XVIII of the Act. If all of the foregoing conditions are met, the Secretary or

CMS Administrator may specify the extent to which a waiver or modification of a

specific Medicare requirement is to be applied within the geographic area(s) with respect

to which the waiver authority has been invoked.

The waiver of a Medicare requirement based on authority included in the provision of

Title XVIII of the Act or its implementing regulations may be made at the discretion of

the Administrator of CMS unless otherwise specified. Such a waiver does not require

either a Presidential or a Secretarial declaration nor, if such declarations are made, would

such a waiver be necessarily limited by the geographic boundaries specified in such

declarations. Nevertheless, the Administrator may elect to limit the effect of “Title XVIII

waivers” to such geographic areas and to such time frames as are specified by such

declarations.

A Medicare requirement established in statute or regulation that is not subject to waiver

under either of these types of “formal waiver” generally may not be waived as a matter of

administrative discretion. Because most Medicare requirements are not “waivable,”

nearly all Medicare entitlement, coverage, and payment rules will remain in effect during

a disaster or emergency.

Informal Waivers: An “informal waiver” is a discretionary waiver or relaxation of a

procedural norm, when such norm is not required by statute or regulation, but rather is

reflected in CMS guidance or policy. Such norm may be waived or relaxed

administratively if circumstances warrant. One example of such a norm would be claims

filing jurisdiction. In the event of a disaster/emergency that impaired or limited

operations at a particular Medicare Administrative Contractor (MAC), alternative claims

filing jurisdictions could be established. Informal waivers are made by the CMS

Administrator or his/her delegates.

Further Instructions in the Event of a Disaster or Emergency: In the event of a disaster or

emergency, CMS will issue specific guidance to MACs via one or more Technical

Direction Letter (TDL) that will contain a summary of the Secretary’s declaration (if

any); specify the geographic areas affected by any declarations of a disaster or

emergency; specify what formal waivers and/or informal waivers, if any, have been

authorized; specify the beginning and end dates that apply to the use of the DR condition

code and/or the CR modifier; and specify what other uses of the condition code and/or

modifier, if any, will be mandatory for the particular disaster/emergency.

Reporting Utilization of the Condition Code and Modifier: MACs must compile reports

of utilization of the use of the condition code and/or modifier as specified via any TDL as

may be issued in the event of a specific disaster or emergency.

B. Policy:

The DR Condition Code:

• The DR condition code is used for institutional billing only.

• Use of the DR condition code is required when a service is affected by an

emergency or disaster and Medicare payment for such service is conditioned on

the presence of a “formal waiver” (as that term is described in “Background”,

above)

• Use of the DR condition code also may be required when either the A/B MAC

(A) or (HHH) or CMS determine that such use is needed to efficiently and

effectively process claims or to otherwise administer the Medicare fee-for-service

program.

• The DR condition code is used at the claim level when all of the services/items

billed on the claim are related to the emergency/disaster.

The CR Modifier:

• The CR modifier is used for Part B items and services only but may be used in

either institutional or non-institutional billing.

• Use of the CR modifier is required when an item or service is impacted by an

emergency or disaster and Medicare payment for such item or service is

conditioned on the presence of a “formal waiver” (as that term is described in

“Background”, above)

Use of the CR modifier also may be required when either the A/B MAC (A), (B), or

(HHH), or DME MAC or CMS determine that such use is needed to efficiently and

effectively process claims or to otherwise administer the Medicare fee-for-service

program.
