Chapter 21
Standardization Codes

21.1 Overview

This section contains information for those electronic billers receiving the electronic remittance file in either the National Standard Format (NSF) or the ANSI ASC X12 format. Electronic billers receiving the remittance file receive the standardized codes in order to convey the reason for claim/line level adjudication. The following sections contain the ANSI and Medicare standardized codes and messages that are provided within your electronic remittance file.

21.2 ANSI Group Codes

An ANSI Group Code is always shown with each ANSI reason code to indicate when you may or may not, bill a beneficiary for the non-paid balance of the services or equipment you furnished. Group codes are not used with Medicare Reference (REF) or Medicare Outpatient Adjudication (MOA) remark code entries.

a. PR - Patient Responsibility

A PR group code signifies the amount that may be billed to the beneficiary or to another payer on the beneficiaryĺs behalf. For example, PR would be used with the reason code for patient deductible or coinsurance, if the patient assumed financial responsibility for a service not considered reasonable and necessary, for the cost of therapy or psychiatric services after the coverage limit had been reached, for a charge denied as result of the patientĺs failure to supply primary payer or other information, or where a patient is responsible for payment of excess non-assigned physician charges. Charges that have not been paid by Medicare and/or are not included in a PR group, such as a late filing penalty (reason code B4), excess charges on an assigned claim (reason code 42), excess charges attributable to rebundled services (reason code B15), charges denied as result of the failure to submit necessary information by a provider who accepts assignment, or services that are not reasonable and necessary for care (reason code 50 or 57) for which there are no indemnification agreements are the liability of the provider. Providers may be subject to penalties if they bill a patient for charges not identified with the PR group code.

b. CO - Contractual Obligations

A CO group code identifies amounts for which the provider is financially liable. These include, participation agreement violations, assignment amount violations, excess charges by a managed care plan provider, late filing penalties, Gramm-Rudman reductions, or medical necessity denials/reductions. The patient may not be billed for these amounts.

c. OA - Other Adjustment

An OA group code is used when neither PR nor CO applies. At least one PR, CO or OA group code appears on each remittance advice. For example, OA would be used when a claim is paid in full at initial adjudication with reason code 93 and a zero amount, or with reason codes such as 69-85 that are components of payments rather than adjustments to payments. Neither the patient nor the provider can be held responsible for any amount classified as an OA adjustment.

d. CR - Correction to or Reversal of a Prior Decision

A CR group code is used whenever there is a change to a previously adjudicated claim. CR explains the reason for the correction; PR, CO and/or OA must always be used in tandem with CR to show the revised information. Separate reason code entries must be used in the NSF for the CR group entry, and any other groups that apply to the readjudicated claim.

21.3 ANSI REASON CODES

ANSI reason codes explain the reasons for any financial adjustments to claims, such as denials, reductions or increases in payment.

21.4 Medicare Reference (REF) Remark Codes

Remark codes must be used to relay service-specific Medicare informational messages that cannot expressed with a reason code. Medicare remark codes are maintained by HCFA.

Remark codes and messages must be used whenever they apply. Although contractors may use their discretion to determine when certain remark codes apply, they do not have discretion as to whether to use an applicable remark code in a remittance notice. A limitation of liability message (m25-M27) must be used where applicable. An unlimited number of Medicare line level remark codes may be entered as warranted in an X12 835 Remittance Advice; there is a limit of 5 line level remark code entries in a NSF Remittance Advice and on a standard paper remittance notice.

a. Line Level Remark Codes

If you believe the service should have been fully covered as billed, or if you did not know and could not reasonably have been expected to know that we would not pay for this (more extensive) service, or if you notified the patient in writing in advance that we would not pay for this (more extensive) service and he/she agreed in writing to pay, ask us to review your claim within six months of receiving this notice. If you do not request review, we will, upon application from the patient, reimburse him/her for the amount you have collected from him/her (for the/in excess of any deductible and coinsurance amounts applicable to the less extensive) service. We will recover the reimbursement from you as an overpayment.
M26

Payment has been (denied for the/made only for a less extensive) service because the information furnished does not substantiate the need for the (more extensive) service. If you have collected (any amount from the patient/any amount that exceeds the limiting charge for the less extensive service), the law requires you to refund that amount to the patient within 30 days of receiving this notice.

The law permits exceptions to the refund requirement in two cases:

  • If you did not know, and could not have reasonably been expected to know, that we would not pay for this service: or
  • If you notified the patient in writing before providing the service that you believed that we were likely to deny the service, and the patient signed a statement agreeing to pay for the service.

If you come within either exception, or if you believe the carrier was wrong in its determination that we do not pay for this service, you should request review of this determination within 30 days of receiving this notice. Your request for review should include any additional information necessary to support your position.

If you request review within the 30-day period, you may delay refunding the amount to the patient until you receive the results of the review. If the review decision is favorable to you, you do not need to make any refund. If, however, the review is unfavorable, the law specifies that you must make the refund within 15 days of receiving the unfavorable review decision.

The law also permits you to request review at any time within six months of receiving this notice. A review requested after the 30-day period does not permit you to delay making the refund. Regardless of when a review is requested, the patient will be notified that you have requested one, and will receive a copy of the determination.

The patient has received a separate notice of this denial decision. The notice advises that he/she may be entitled to a refund of any amounts paid, if you should have known that we would not pay and did not tell him/her. It also instructs the patient to contact your office if he/she does not hear anything about a refund within 30 days.

The requirements for refund are in ž1842(l) of the Social Security Act and 42CFR411.408. The section specifies that physicians who knowingly and willfully fail to make appropriate refunds may be subject to civil monetary penalties and/or exclusion from the program.

Please contact this office if you have any questions about this notice.

M27 The beneficiary has been relieved of liability of payment of these items and services under the limitation of liability provision of the law. You, the provider, are ultimately liable for the beneficiary's waived charges, including any charges for coinsurance, since the items or services were not reasonable and necessary or constituted custodial care, and you knew or could reasonably have been expected to know, that they were not covered.

You may appeal this determination provided that the beneficiary does not exercise his/her appeal rights. If the beneficiary appeals the initial determination, you are automatically made a party to the appeals determination. If, however, the beneficiary or his/her representative has stated in writing that he/she does not intend to request a reconsideration, or the beneficiary's liability was entirely waived in the initial determination, you may initiate an appeal.

You may ask for a reconsideration for hospital insurance (or a review for medical insurance) regarding both the coverage determination and the issue of whether you exercised due care. The request for reconsideration must be filed within 60 days (or 6 months for a medical insurance review) from the date of this notice. You may make the request through any Social Security office or through this office.

21.5 Medicare Outpatient Adjudication (MOA) Remark Codes

MEDICARE CLAIM LEVEL REMARKS CODES

A maximum of 5 of these claim level Medicare Inpatient Adjudication (MIA) and 5 of these claim level Medicare Outpatient
Adjudication (MOA) remarks codes may be used per claim. See the Medicare 835 Implementation Guides. Insert these codes
in the space for semantics 5 or 20-23 of the MIA segment or semantics 3-7 of the MOA segment as applicable. Previously
established MIA/MOA semantic codes [MIA01, 03-04, 06-19 and 24, and MOA01-02 and 08-09] are not impacted by this
instruction and must continue to be used as indicated in the Medicare Part A 835 Implementation Guide. MIA01, 03-04,
06-19 and 24, and MOA01-02 and 08-09 as listed in the Part A 835 Implementation Guide do not apply to the NSF, but
individual Medicare MIA/MOA remarks codes listed in this document must also be used in the NSF and the standard paper
remittance notice. See NSF and standard paper remittance notice specifications for use of Medicare MIA/MOA remarks
codes in NSF and paper RAs.

Medicare MIA/MOA remarks codes are used to convey appeal information and other claim-specific information that does
not involve a financial adjustment. As with the 835/NSF reason and Medicare line level remarks codes, Medicare
contractors are also prohibited from use of local MIA/MOA codes.

An appropriate appeal, limitation of liability or other message must be used whenever applicable. Although contractors have
discretion to determine when certain remarks codes and messages apply, they do not have discretion as to whether to use
applicable codes and messages.

 
Code Value Description
MA01 (Initial Part B determination, carrier or intermediary)--If you do not agree with what we approved for these services, you may appeal our decision. To make sure that we are fair to you, we require another individual that did not process your initial claim to conduct the review. However, in order to be eligible for a review, you must write to us within 6 months of the date of this notice, unless you have a good reason for being late. If you meet the criteria for a telephone review, you should phone this office if you wish to request a telephone review.  
MA02 (Initial Part A determination)--If you do not agree with this determination, you have the right to appeal. You must file a written request for a reconsideration within 60 days of receipt of this notification. Decisions made by a PRO must be appealed to that PRO. (An institutional provider, e.g., hospital, SNF, HHA, may appeal only if the claim involves a medical necessity denial, a SNF noncertified bed denial, or a home health denial because the patient was not homebound or was not in need of intermittent skilled nursing services, and either the patient or the provider is liable under ž1879 of the Social Security Act, and the patient chooses not to appeal.)  
MA03 (Hearing) If you do not agree with the Medicare approved amounts and $100 or more is in dispute (less deductible and coinsurance) , you may ask for a hearing. You must request a hearing within six months of the date of this notice. To meet the $100, you may combine amounts on other claims that have been reviewed/reconsidered. This includes reopened reviews if you received a revised decision. You must appeal each claim on time. At the hearing, you may present any new evidence which could affect our decision.
