CMS Pub. 100-08, ch. 3, § 3.2.3.7
Special Provisions for Lab ADRs
This section applies to MACs, CERT, RACs, UPICs, and SMRC as
indicated.
ICD-10-CM is used for diagnoses on inpatient discharges and for other services provided
upon implementation of ICD-10.
When the MACs, CERT, RACs, SMRC, and UPICs send an ADR for a lab service, the
following documentation shall be requested from the billing lab:
• The order for the service billed (including sufficient information to
allow the reviewer to identify and contact the ordering provider);
• Verification of accurate processing of the order and submission of
the claim; and
• Diagnostic or other medical information supplied to the lab by the
ordering provider, including any diagnosis codes or narratives.
The contractor shall deny the claim if a benefit category, statutory exclusion, or coding
issue is in question, or send an ADR to the ordering provider to determine medical
necessity. The contractor shall review information from the lab and find it insufficient
before the ordering provider is contacted. The contractor shall send an ADR to the
ordering provider that shall include sufficient information to identify the claim in
question.
If the documentation received does not demonstrate that the service was reasonable and
necessary, the contractor shall deny the claim. These denials are considered medical
record reviews. Contractor denial notices shall remind providers that beneficiaries cannot
be held liable for these denials unless they received proper liability notification before
services were rendered, as detailed in CMS Pub. IOM 100-04, chapter 30.
