Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

General laboratory reimbursement criteria

Covered when ALL of the following reimbursement and documentation requirements are met:

Services reported on the CMS-1500 (or electronic equivalent) must be accurately coded and describe the services performed.

The performing provider must meet applicable certification and billing responsibilities (including a valid CLIA certificate on file when required).

Diagnostic laboratory tests must be ordered by the treating physician or Other Qualified Health Care Professional (Other QHP) and the order must document the specific test(s) to be performed (generic instructions such as 'run labs' are insufficient).

Documentation examples: signed requisition listing specific tests, an unsigned requisition with an authenticated medical record supporting intent, authenticated medical record entries, or standardized electronic requisitions.

Duplicate laboratory services submitted by the Same Group Physician or Other QHP or by multiple providers are generally reimbursable only once; repeat or distinct services require appropriate modifiers to be considered for separate reimbursement.

Acceptable modifiers include 91 for repeats and 59 or selective EPSU modifiers (XE, XP, XS, XU) for distinct services; do not use modifiers 76 or 77 to indicate repeat laboratory services.

Laboratory services performed in a facility place of service (POS 19, 21, 22, 23, 26, 34, 51, 52, 55, 56, 57, 61) are reimbursable to the facility; independent/reference/non-reference providers will not be reimbursed for those facility-performed manual or automated services unless a specific exception applies.

Exceptions include certain reproductive laboratory procedures, molecular pathology/Genomic Sequencing Procedures and proprietary laboratory analyses when the facility is not equipped to perform the testing and appropriately refers it.

UnitedHealthcare may apply other reimbursement policies (for example, Rebundling, CCI Editing, CLIA ID requirement, and Professional/Technical Component policies) which may affect payment determinations.

Laboratory coverage and billing criteria

Coverage is contingent on proper ordering, documentation, correct coding (including panel bundling), appropriate place-of-service/provider type, and use of modifiers to indicate distinct services.

Diagnostic laboratory tests must be ordered by the treating physician or Other QHP and documentation must clearly indicate the specific test(s) to be performed; generic documentation (e.g., 'run labs') does not support the order.

Facility-performed manual and automated laboratory services submitted with facility POS (19,21,22,23,26,34,51,52,55,56,57,61) are reimbursable to the facility only; Independent, Reference, or Non-Reference laboratories will not be reimbursed for those services when performed in a facility setting, except for specified exceptions.

UnitedHealthcare uses CMS NPFS PC/TC indicators 3 and 9 to identify services not reimbursable to independent/reference labs in facility settings.

Panel component coding: when all component codes comprising a CPT organ- or disease-oriented panel (e.g., 80047–80081) are submitted by the Same Individual Physician or Other QHP for the same patient on the same date of service, UnitedHealthcare will bundle to and reimburse the comprehensive panel code; if fewer than all components are submitted, components are considered individually.

Follow CPT guidance when overlapping panels are reported: report the panel incorporating the greater number of tests and report remaining tests individually.

S9529	Non-reimbursable per UnitedHealthcare — place-of-service descriptor; venipuncture better represented by 36415 with appropriate POS.
G0471	Specimen collection by laboratory for home health agency or collection from skilled nursing facility — reimbursable only in those specific situations per CMS guidance.

Drug Assay CodingCPTNot Covered

80320-80377

Drug assay CPT codes — considered non-reimbursable consistent with CMS; may be reported under appropriate HCPCS codes instead.

Date of Service determination

Date of ServiceSpecimen collection date (or collection end date if over 2 days). Exceptions for ADLT and certain molecular pathology tests when criteria met.

Panel bundling threshold

Panel bundling thresholdBundling occurs when all components comprising a panel are submitted by the Same Individual Physician or Other QHP for the same patient on the same date of service.

Provider Responsibilities and Billing Requirements

Billing Rule

CLIA and Billing Responsibility

A valid Federal Clinical Laboratory Improvement Amendments (CLIA) Certificate Identification number is required for reimbursement of clinical laboratory services reported on a CMS 1500 Health Insurance Claim Form or its electronic equivalent. Providers may only bill for laboratory services that they or their staff perform; pass-through billing is not permitted. UnitedHealthcare (Colorado Rocky Mountain Health Plans) will only reimburse for laboratory services that the billing provider is certified to perform through the federal CLIA. Do not bill members for laboratory services if you do not have the applicable CLIA certification.

A CLIA number must be present on claims for clinical laboratory reimbursement.
Providers without appropriate CLIA certification must not bill members for the service.
Pass-through billing is not permitted; bill only for services your organization performed.

Documentation Required

Ordering and Documentation Requirement

All diagnostic laboratory tests must be ordered by the treating physician or Other Qualified Health Care Professional (Other QHP) and used in the management of the patient’s condition. The physician’s or Other QHP’s documentation must clearly indicate the specific tests to be performed; vague instructions (for example, 'run labs' or 'check blood') do not support intent to order. The medical record must include both the order/intention and a copy of the test results.

Acceptable evidence of an order or intent to order includes: a signed order or requisition listing the specific test(s).
An unsigned order or requisition listing the specific test(s) together with an authenticated medical record (progress notes or office notes) supporting the provider’s intent to order the tests.
An authenticated medical record (e.g., office or progress notes) that documents the provider’s intent to order specific test(s).
Electronic requisitions are acceptable when the laboratory can demonstrate the order was received via a standardized electronic process.

Definitions

inv-16: POS

DefinitionPlace of Service (POS) designates where the specimen was collected and determines facility vs non-facility treatment for reimbursement.

Facility POS codesFor this policy, facility POS are 19, 21, 22, 23, 26, 34, 51, 52, 55, 56, 57, and 61.

Non-facility examplesOther POS such as 11 (physician office) and 81 (independent/reference laboratory when specimen obtained there) are treated as non-facility unless listed as facility POS.

inv-17: DOS

Primary definitionDate of Service (DOS) is the date the specimen was collected; if collected over two calendar days, DOS is the date collection ended.

Exception noteUnitedHealthcare will make exceptions for ADLT and certain molecular pathology tests when specified conditions are met (see exception criteria).

Claim reportingReport DOS on CMS-1500 (or electronic equivalent) based on specimen collection date unless exception applies.

inv-18: Independent Laboratory

DefinitionIndependent Laboratory: a laboratory independent of an attending physician's office and of a hospital; must meet Federal and State certification and CLIA requirements.

POS reportingIf the specimen is obtained in an Independent Laboratory, POS 81 is reported to identify the location of specimen collection.

Certification requirementIndependent Laboratories must meet CLIA and proficiency testing requirements to qualify for reimbursement when billing services they perform.

inv-19: Reference Laboratory

DefinitionReference Laboratory: a laboratory that receives a specimen from another (referring) laboratory and actually performs the test; often referred to as an Independent Laboratory.

Reporting guidanceWhen an entity refers a specimen to a Reference Laboratory, the performing lab should report the service and append identifying modifiers (e.g., 90) when appropriate.

Relationship to referring labA Referring Laboratory sends the specimen to the Reference Laboratory for performance of the test; reimbursement follows guidance for the performing laboratory.

inv-20: Same Individual Physician or Other Qualified Health Care Professional

DefinitionSame Individual Physician or Other Qualified Health Care Professional: the same individual rendering services reporting the same Federal Tax Identification number.

Relevance to bundlingPanel bundling and component inclusion rules apply when component codes are submitted by the Same Individual Physician or Other QHP for the same patient on the same DOS.

Duplicate services implicationDeterminations about duplicate laboratory services and reimbursement precedence consider whether services were submitted by the Same Individual or Same Group of providers.

inv-21: CMS NPFS Status Indicator A/R/T

DefinitionCMS NPFS Status Indicators A/R/T identify reimbursement characteristics: A = Active (paid separately if covered), R = Restricted (special coverage instructions), T = Injections (bundling rules apply).

UsageUnitedHealthcare uses these status indicators (and PC/TC indicators) to identify codes' reimbursement characteristics and to determine purchased diagnostic tests and facility reimbursement rules.

Policy notePresence of an A indicator does not imply a national Medicare coverage determination; carriers remain responsible for coverage decisions in absence of national policy.
