Genetics Billing Services
Genetics billing is different from most specialties because the main product is often a lab test, not a visit. Test codes are detailed, sometimes tied to a specific gene or panel, and they change often. Payers may also require prior authorization and proof that the patient meets criteria set in a medical policy.
Clinics also face questions about who orders, who performs, and who bills for each step. Genetic counselors may not be able to bill on their own under some payers. Westmont Revenue Partners connects genetics practices with vetted billing experts who understand molecular coding, coverage rules, and the paperwork behind each test.

Billing challenges in genetics
Test-specific coding. Many tests have their own code, and an unlisted code is used when none fits. A genetics biller matches the lab report to the right code and supplies a description when one is required.
Prior authorization and medical policy. Payers often limit testing to patients who meet family history or clinical criteria. Experienced billers gather pedigrees, notes, and prior results before submitting a request.
Who bills for the test. The ordering clinic, the lab, and any reference lab each have a role. Billers confirm who submits the claim so the same test is not billed twice.
Genetic counselor billing. Many payers do not enroll genetic counselors as billing providers. Billers learn each plan's rules and often bill under a supervising physician where allowed.
Diagnosis coding for testing. A family history or a known variant may support coverage, but the code must match the test's purpose. Coders query providers when the reason for testing is unclear.
Panel and add-on rules. Payers may pay once for a panel and deny extra tests as duplicates. Billers review what was ordered and what was actually run.
Changing coverage. Policies shift as evidence grows. Billing teams review policy updates before they affect denials.

Frequently asked questions
How are genetic tests billed?
Genetic tests are billed with molecular codes that describe the gene or panel, or with an unlisted code when no specific code exists. The lab usually bills for the test, while the clinic bills for visits and counseling. Confirm who bills each part to avoid duplicates.
Can genetic counselors bill insurance?
It depends on the payer and the state. Some plans recognize genetic counselors, while many do not. In other cases, counseling is billed under a supervising physician or included in a visit. A genetics billing company can check each plan's rules.
Do genetic tests need prior authorization?
Often. Many payers require approval for hereditary cancer panels, exome sequencing, and other large tests. They usually ask for notes that show the patient meets policy criteria. Check each payer's current medical policy before ordering.
Why do genetic test claims get denied?
Common reasons include missing criteria, use of an unlisted code, duplicate panels, and billing by the wrong party. Sometimes the test is considered experimental. A biller reviews the denial reason, the policy, and the appeal path.
What does an unlisted molecular code mean for payment?
An unlisted code means no specific code describes the test. Payers often review the claim by hand and may ask for lab details and price information. This can slow payment, so billers prepare supporting documents ahead of time.
