Panel bundling edits
Component tests that add up to a defined panel must be billed as the panel. Billing components separately is an unbundling finding, not just a denial.
Laboratory billing
laboratory billingservices
Laboratory billing is a throughput problem with a compliance edge. Volume hides small systematic errors, and a single mis-set panel rule or missing modifier can repeat across thousands of claims before it shows up in the deposit.
What actually gets denied
Laboratory denials we workevery single day.
Medical necessity and ABNs
Tests failing a national or local coverage determination need a signed advance beneficiary notice and the GA modifier to shift liability. Without it, the balance is not the patient's.
Ordering provider and diagnosis capture
Labs depend on data supplied by the ordering practice. Missing NPI or a non-specific diagnosis denies at the front door.
Molecular and genetic testing
PLA codes, Z-codes and prior authorization requirements vary by payer and change frequently.
Payer behavior
The quirks that decide whether you get paid
Clinical lab fee schedule pricing
Many tests are priced on a fee schedule that ignores billed charges entirely; underpayment review must compare against that schedule.
Reference lab pass-through rules
Who may bill for a referred test is regulated and payer-specific, with anti-markup limits.
Frequency limits
Routine monitoring tests carry per-period limits that deny silently.
Documentation traps
What we ask your providers to write down
Standing orders without renewal
Recurring test orders expire and must be renewed with documented necessity.
Signature requirements on requisitions
An unsigned or undated requisition cannot support the claim on audit.
Specimen source and date mismatches
Collection date drives the date of service and, for some tests, coverage itself.
