Explanation

XX7 E0 (zero) Change in patient status

The provider may not submit more than one claim change reason code per adjustment

request. It must choose the single reason that best describes the adjustment it is requesting.

It should use claim change reason code D1 only when the charges are the only change on the

claim. Other claim change reasons frequently change charges, but the provider may not

"add" reason code D1 when this occurs.

The claim change reason code is entered as a condition code on the ASC X12 837

institutional claim format or on the hard copy Form CMS-1450 For reason codes D0-D4 and

D7-D9, submit a debit-only adjustment request, bill type XX7. For reason codes D5 and D6,

submit a cancel-only adjustment request, bill type XX8.

B. - Edits on Claim Change Reason Codes

The following edits are based on the claim change reason code. The A/B MAC (A) must

apply them to each incoming adjustment request.

• If the type of bill is equal to XX7 and the claim change reason code is not equal to

D0-D4, D7-D9, or E0, the A/B MAC (A) rejects the request back to the provider with

the following error message, "Claim change reason code must be present and equal to

D0-D4, D7-D9, or E0 for a debit-only adjustment request."

• If the type of bill is equal to XX8 and the claim change reason code is not equal to

D5-D6, the A/B MAC (A) rejects the request back to the provider with the following

error message, "Claim change reason code must be present and equal to D5-D6 for a

cancel-only adjustment request."

• If the type of bill is equal to XX7 or XX8 and the ICN/DCN of the claim being

adjusted is not present, the A/B MAC (A) rejects the request back to the provider

with the following message, "ICN/DCN of the claim being adjusted is required for an

adjustment request."

• If more than one claim change reason code is present on the provider's request, the

A/B MAC (A) rejects the request back to the provider with the following message,

"only one claim change reason code may apply to a single adjustment request from a

provider. Choose the single claim change reason code that best describes the reason

for the provider's request and resubmit."

• If the provider submits an adjustment request as type of bill not equal to XX7 or

XX8, the A/B MAC (A) rejects the request back to the provider with the message,

"Provider submitted adjustment request must use type of bill equal to XX7 or XX8."

• If the claim change reason code is equal to D0, the A/B MAC (A) compares the

beginning and ending dates on the provider's request to those on the claim to be

adjusted on its history. If these dates are the same, it rejects the request back to the

provider with the message, "Dates of service must change for claim change reason

code D0."

• If the claim change reason code is equal to D1, the A/B MAC (A) compares the total

and line item charges on the provider's request to those on the claim to be adjusted on

its history. If these changes are the same, the A/B MAC (A) rejects the request back

to the provider with the message, "Charges must be changed for claim change reason

code D1."

• If the claim change reason code is equal to D2, the A/B MAC (A) compares revenue

codes/HCPCS on the provider's request to those on the claim to be adjusted on its

history. If these codes are the same, it rejects the request back to the provider with

the message, "Revenue codes/HCPCS must change for claim change reason code

D2."

• If the claim change reason code is equal to D3, the A/B MAC (A) compares the

ending date on the provider's request to that on the claim to be adjusted on its history.

If these dates are the same, it rejects the request back to the provider with the

message, "Thru dates must change for the claim change reason code D3."

• If the claim change reason code is equal to D4, the A/B MAC (A) compares

diagnosis and procedure codes on the provider's request to those on the claim to be

adjusted on its history. If these codes are the same and are in the same sequence, it

rejects the request back to the provider with the message, "Diagnoses and/or

procedures must change for claim change reason code D4."

• If the claim change reason code is equal to D5 or D6, type of bill must be equal to

XX8 on the provider's request. If type of bill is not equal to XX8, the A/B MAC (A)

rejects the request back to the provider with the message, "Type of bill must be equal

to XX8 for claim change reason codes D5 or D6."

• If the claim change reason code is equal to D7, an MSP value code (12-16, 41-43, or

47) must be present, if a value code, 12-16, 41-43, or 47, is not present, the A/B

MAC (A) rejects the request back to the provider with the message, "An MSP value

code (12-16, 41-43, or 47) must be present for claim change reason code D7."

• If the claim change reason code is equal to D7, and one or more of value codes 12-16,

41-43, and/or 47 is present but each value amount is equal to 0 (zero) or spaces, the

A/B MAC (A) rejects the request back to the provider with the message, "invalid

value amount for claim change reason code D7."

• If the claim change reason code is equal to D8, and a value code 12-16, 41-43, or 47

is present, the A/B MAC (A) rejects the claim back to the provider with the message,

"Invalid value code for claim change reason D8."

• If the claim change reason code is equal to E0, the A/B MAC (A) compares patient

status on the provider's request to that on the claim to be adjusted. If patient status is

the same, the A/B MAC (A) rejects the request back to the provider with the

message, "Patient status must change for claim change reason E0."

If an adjustment the provider initiates results in a change to a higher weighted DRG, the A/B

MAC (A) edits the adjustment request to insure it was submitted within 60 days of the date

of the remittance for the claim to be adjusted. If it is, the A/B MAC (A) processes the claim

for payment. If the remittance date is more than 60 days prior to the receipt date of the

adjustment request and results in a change to a lower weighted DRG, the A/B MAC (A)

processes the claim for payment and forwards it to CWF.

The A/B MAC (A) must suspend for investigation all adjustment requests with claim change

reason codes D4, D8, and D9. Providers that consistently use D9 will be investigated and, if

a pattern of abuse is evident, may be reported to the OIG.

C. - Additional edits

The A/B MAC (A) must perform the following additional edits and investigate adjustment

requests the provider submits:

• A full denial once the bill is paid, except to accomplish retraction of a duplicate

payment;

• A change in DRG based on a change in age or sex;

• A change in deductible;

• An adjustment request that changes a previously submitted QIO adjustment request;

• An adjustment of a bill due to a change in utilization or spell data on another bill;

• A reopening to change a no-payment bill to a payment bill;

• A reopening to pay a previously denied line item;

• An adjustment request the provider initiates with a claim change reason code equal to

D7, with the Medicare payment amount equal to or greater that the previously paid

amount; or

• An adjustment request with a claim change reason code equal to E0, and the claim is

for a PPS provider. The A/B MAC (A) must investigate if the change is from patient

status 02, transferred to another acute care facility.
