 is continuing to make other technical, clarifying and conforming changes in the NCD manual and they are also clarifying the existing policy related to diagnostic tests for Somatic (Acquired) Cancer. If CMS were to make material revisions to policy, this could potentially impact the scope of clonoSEQ coverage. 

Under Medicare Part B, payment for most diagnostic laboratory tests is made under the Clinical Laboratory Fee Schedule (“CLFS”), which assigns payment amounts to tests based on billing codes. Under the Protecting Access to Medicare Act of 2014 (“PAMA”), certain laboratories that receive the majority of their Medicare revenue from payments made under the CLFS or Medicare’s Physician Fee Schedule are required to report to CMS every three years, or annually for “advanced diagnostic laboratory tests,” commercial payor payment rates and volumes for tests they perform and that are assigned specific billing codes. PAMA has special provisions relating to “advanced diagnostic laboratory tests,” as defined by the statute, and these provisions affect the rate-setting at the time of launch and the periodicity of rate reporting and revision. Laboratories that fail to report the required payment information may be subject to substantial civil monetary penalties. If, in the future, clonoSEQ or any of our tests are assigned a specific code we would be required to report commercial payor payment data on those tests. Payments for tests billed under miscellaneous codes are determined by the MACs, which also have discretion to change those payment rates. 

CMS uses the data reported by laboratories to calculate a payment rate for each CLFS test, other than those coded with miscellaneous codes and certain others, based on the volume-weighted median of the private payor rates. These rates apply for three years, except that payment rates for advanced diagnostic laboratory tests apply for one year. If we offer tests with specific codes, this apparatus will apply. Under these circumstances, Medicare’s payment rates would be determined by the rates we and other laboratories, if any, with tests that share the specific codes we use, obtain from commercial payors. In that case, if we are unable to obtain and maintain adequate reimbursement rates from commercial payors, this may adversely affect our Medicare rates. 

In some circumstances, our tests may be furnished to hospital inpatients and paid by Medicare under different rules. For example, when a specimen is obtained from a patient who is at the time classified by Medicare as a hospital inpatient, Medicare would not make a separate payment for the test and we would have to look to the hospital for payment. We do not know how often this will
