How we see molecular & genetic testing billing.
Reviewed by the VisMed diagnostics & laboratory billing team
Genetic and molecular tests are expensive, new, and covered under policies that each payer writes and rewrites. Most require authorization per test, with clinical criteria the ordering physician must document. Many require a registered test identifier in addition to the procedure code. Some have proprietary codes, some use unlisted codes with documentation, and the mapping changes as codes are added.
The ordering physician is rarely aware of any of this. The laboratory receives a specimen with a requisition and discovers at denial that no authorization existed, or that the payer’s policy excludes the test for that indication. By then the test has been run and the reagents spent.
VisMed maintains a policy library per payer and per test, runs an authorization desk that works with the ordering office before the specimen is processed, keeps identifier registration and code mapping current, and builds appeals on the payer’s own clinical criteria.
Where molecular & genetic testing practices lose money
The patterns we find in the aging and denial history before anything else changes.
Tests run without authorization
Where authorization is required and absent, the claim is denied and the patient often cannot be billed. The test has already been run.Indication outside policy
Each payer covers each test for specific indications and criteria. Orders that do not meet them are denied on medical necessity.Missing identifiers and code mapping errors
Registered test identifiers required by some payers, and code changes for proprietary tests, produce rejections when they are missing or out of date.Unlisted codes without documentation
Tests billed under unlisted codes need a description and pricing support, or they are denied or paid arbitrarily.Appeals without clinical criteria
Denials for molecular tests are winnable when the appeal is built on the payer’s own criteria and the clinical documentation. Generic appeals lose.
What we do differently for molecular & genetic testing
Specialty-matched coders and a denials specialist, working inside your own system.
We maintain the policy library
Coverage criteria, authorization requirements and code mapping are maintained per payer and per test by your account team, and applied at intake.Our authorization desk works with ordering offices
We initiate requests and gather clinical documentation from the ordering physician before the specimen is processed, and give the ordering office a simple checklist.We keep identifiers and codes current
Registered identifiers and proprietary codes are maintained per test and applied automatically.We appeal on the payer’s criteria
Denials are appealed with the payer’s policy language and the clinical documentation, and tracked to outcome.

Molecular & genetic testing billing, asked and answered.
What a physician-owner in this specialty asks on the first call.
How does VisMed get authorizations when the ordering physician is not our employee?
By working directly with the ordering office. VisMed initiates the request, asks for the clinical documentation with a short checklist specific to the payer and test, and holds the specimen until the authorization is in place where the policy requires it.
How does VisMed keep up with payer policy changes?
VisMed maintains a policy library per payer and per test continuously, with changes applied to intake rules as they take effect. Your account team is responsible for keeping it current for the tests you run.
Does VisMed handle registered test identifiers?
VisMed handles registration, maintenance and application on claims for the payers that require them.
Are molecular denials worth appealing?
Often, yes, because the amounts are significant and the denials are frequently wrong against the payer’s own criteria. VisMed builds appeals on the policy language and the clinical record, and tracks them to outcome.
How does VisMed bill tests that only have an unlisted code?
With the documentation the payer needs to price it: a description of the test, its components and the comparable coded test, attached to the claim rather than sent on request. VisMed keeps a pricing file per unlisted test per payer so the first submission is complete.
