Instructions for Services Provided on and After January 1, 2011

Section 153b of the MIPPA requires that all ESRD-related laboratory tests must be reported by the ESRD facility whether provided directly or under arrangements with an independent laboratory. When laboratory services are billed by providers other than the ESRD facility and the laboratory test furnished is designated as a laboratory test that is included in the ESRD PPS (ESRD-related), the claim will be rejected or denied. In the event that an ESRD-related laboratory test was furnished to an ESRD beneficiary for reasons other than for the treatment of ESRD, the provider may submit a claim for separate payment using modifier AY. The AY modifier serves as an attestation that the item or service is medically necessary for the dialysis patient but is not being used for the treatment of ESRD. The items and services subject to consolidated billing located on the CMS website includes the list of ESRD-related laboratory tests that are routinely performed for the treatment of ESRD.

For services provided on or after January 1, 2011, the 50/50 rule no longer applies to independent laboratory claims for AMCC tests furnished to ESRD beneficiaries. The 50/50 rule modifiers (CD, CE, and CF) are no longer required for independent laboratories effective for dates of service on and after January 1, 2011. However, for services provided between January 1, 2011 and March 31, 2015, the 50/50 rule modifiers are still required for use by ESRD facilities that are receiving the transitional blended payment amount (the transition ends in CY 2014). For services provided on or after April 1, 2015, the 50/50 rule modifiers are no longer required for use by ESRD facilities.

Effective for dates of service on and after January 1, 2012, contractors shall allow organ disease panel codes (i.e., HCPCS codes 80047, 80048, 80051, 80053, 80061, 80069, and 80076) to be billed by independent laboratories for AMCC panel tests furnished to ESRD eligible beneficiaries if:

• The beneficiary is not receiving dialysis treatment for any reason (e.g., posttransplant beneficiaries), or

• The test is not related to the treatment of ESRD, in which case the supplier would append modifier “AY”.

Contractors shall make payment for organ disease panels according to the Clinical Laboratory Fee Schedule and shall apply the normal ESRD PPS editing rules for independent laboratory claims. The aforementioned organ disease panel codes were added to the list of bundled ESRD PPS laboratory tests in January 2012.

Effective for dates of service on and after April 1, 2015, contractors shall allow organ disease panel codes (i.e., HCPCS codes 80047, 80048, 80051, 80053, 80061, 80069, and 80076) to be billed by ESRD facilities for AMCC panel tests furnished to ESRD eligible beneficiaries if:

• These codes best describe the laboratory services provided to the beneficiary, which are paid under the ESRD PPS, or

• The test is not related to the treatment of ESRD, in which case the ESRD facility would append modifier “AY” and the service may be paid separately from the ESRD PPS.

Instructions for Services Provided Prior to January 1, 2011 For claims with dates of service prior to January 1, 2011, Medicare will apply the following rules to Automated Multi-Channel Chemistry (AMCC) tests for ESRD beneficiaries:

• Payment is at the lowest rate for tests performed by the same provider, for the same beneficiary, for the same date of service.

• The facility/laboratory must identify, for a particular date of service, the AMCC tests ordered that are included in the composite rate and those that are not included. See Publication 100-02, Chapter 11, Section 30.2.2 for the chart detailing the composite rate tests for Hemodialysis, Intermittent Peritoneal Dialysis (IPD), Continuous Cycling Peritoneal Dialysis (CCPD), and Hemofiltration as well as a second chart detailing the composite rate tests for Continuous Ambulatory Peritoneal Dialysis (CAPD).

• If 50 percent or more of the covered tests are included under the composite rate payment, then all submitted tests are included within the composite payment. In this case, no separate payment in addition to the composite rate is made for any of the separately billable tests.

• If less than 50 percent of the covered tests are composite rate tests, all AMCC tests submitted for that Date of Service (DOS) for that beneficiary are separately payable.

• A noncomposite rate test is defined as any test separately payable outside of the composite rate or beyond the normal frequency covered under the composite rate that is reasonable and necessary.

• For carrier processed claims, all chemistries ordered for beneficiaries with chronic dialysis for ESRD must be billed individually and must be rejected when billed as a panel.

(See §100.6UH for details regarding pricing modifiers.)

Implementation of this Policy:

ESRD facilities when ordering an ESRD-related AMCC must specify for each test within the AMCC whether the test:

a. Is part of the composite rate and not separately payable;

b. Is a composite rate test but is, on the date of the order, beyond the frequency covered under the composite rate and thus separately payable; or

c. Is not part of the ESRD composite rate and thus separately payable.

Laboratories must:

a. Identify which tests, if any, are not included within the ESRD facility composite rate payment

b. Identify which tests ordered for chronic dialysis for ESRD as follows:

1) Modifier CD: AMCC Test has been ordered by an ESRD facility or MCP physician that is part of the composite rate and is not separately billable.

2) Modifier CE: AMCC Test has been ordered by an ESRD facility or MCP physician that is a composite rate test but is beyond the normal frequency covered under the rate and is separately reimbursable based on medical necessity.

3) Modifier CF: AMCC Test has been ordered by an ESRD facility or MCP physician that is not part of the composite rate and is separately billable.

c.Bill all tests ordered for a chronic dialysis ESRD beneficiary individually and not as a panel.

The shared system must calculate the number of AMCC tests provided for any given date of service. Sum all AMCC tests with a CD modifier and divide the sum of all tests with a CD, CE, and CF modifier for the same beneficiary and provider for any given date of service.

If the result of the calculation for a date of service is 50 percent or greater, do not pay for the tests.

If the result of the calculation for a date of service is less than 50 percent, pay for all of the tests.

For FI processed claims, all tests for a date of service must be billed on the monthly ESRD bill. Providers that submit claims to a FI must send in an adjustment if they identify additional tests that have not been billed.

Carrier standard systems shall adjust the previous claim when the incoming claim for a date of service is compared to a claim on history and the action is adjust payment. Carrier standard systems shall spread the payment amount over each line item on both claims (the claim on history and the incoming claim).

The organ and disease oriented panels (80048, 80051, 80053, and 80076) are subject to the 50 percent rule. However, clinical diagnostic laboratories shall not bill these services as panels, they must be billed individually. Laboratory tests that are not covered under the composite rate and that are furnished to CAPD end stage renal disease (ESRD) patients dialyzing at home are billed in the same way as any other test furnished home patients.

FI Business Requirements for ESRD Reimbursement of AMCC Tests:

Requirement Number Requirements Responsibility
1.1 The FI shared system must RTP a claim for AMCC tests when a claim for that date of service has already been submitted. Shared system
1.2 Based upon the presence of the CD, CE and CF payment modifiers, identify the AMCC tests ordered that are included and not included in the composite rate payment. Shared System
1.3 Based upon the determination of requirement 1.2, if 50 percent or more of the covered tests are included under the composite rate, no separate payment is made. Shared System
1.4 Based upon the determination of requirement 1.2, if less than 50 percent are covered tests included under the composite rate, all AMCC tests for that date of service are payable. Shared System
1.5 Effective for claims with dates of service on or after January 1, 2006, include any line items with a modifier 91 used in conjunction with the “CD,” “CE,” or “CF” modifier in the calculation of the 50/50 rule. Shared System
1.6 FIs must return any claims for additional tests for any date of service within the billing period when the provider has already submitted a claim. Instruct the provider to adjust the first claim. FI or Shared System
1.7 After the calculation of the 50/50 rule, services used to determine the payment amount may never exceed 22. Effective for claims with dates of service on or after January 1, 2006, accept all valid line items submitted for the date of service and pay a maximum of the ATP 22 rate. Shared System
