Specialty billing · Pathology & Laboratory
Not per container. Not per block. Per specimen.
Get more of your pathology billing services paid on the first submission. 247 Medical Billing Services runs the full revenue cycle for clinical laboratories and pathology groups across Medicare, Medicaid, and commercial payers — anatomic, clinical, and molecular work alike — with a dedicated account manager, a free 360° reporting dashboard, and HIPAA and SOC 2 Type II safeguards behind every claim. We've billed for labs since 2005.
More than almost any other specialty, pathology payment turns on a single structural question: who owns which part of the work. The same surgical specimen can pay two ways and land on two different claims, and getting the component wrong for the setting is the fastest way to turn a payable read into a duplicate denial. These are the rules that decide the money on every case:
Surgical pathology is billed per specimen at the level that matches its complexity — 88302 through 88309 — never per container, per block, or per case. Two separately identified specimens submitted in one jar are two units when documented as distinct; two blocks cut from one specimen are still a single unit. Count in either wrong direction and you either leave money on the bench or draw a downcoding recoupment.
Modifier 26 pays the pathologist's interpretation, modifier TC pays the lab's histology and equipment, and a global claim bills both from one owner-operator. A hospital-based pathologist bills the 26 while the hospital bills the TC under OPPS; an independent lab that owns the whole process bills global. Match the component to the setting or the claim bounces as a duplicate or unbundled service.
Automated chemistry panels — basic and comprehensive metabolic, lipid, hepatic function — are single CPT codes that already bundle their component tests. Bill the individual chemistries when a panel definition is met and NCCI rebundles the lot into a denial; only medically necessary tests outside the panel belong on top of it.
Most automated chemistry and hematology is priced on the Clinical Laboratory Fee Schedule with no 26 to bill, while molecular pathology, flow cytometry interpretation, and special-study reads do carry a payable read. Treat every test the same way and you either miss a billable interpretation or bill one that doesn't exist.
Tier 1 and Tier 2 codes, MAAAs, and proprietary PLA codes are high-dollar and heavily scrutinized. In MolDX jurisdictions each test needs a registered identifier and must satisfy the governing LCD; without the coverage record and the right diagnosis, the most valuable claims on your bench are also the ones most likely to deny.
One panel code
Bill the individual chemistries when a panel definition is met and NCCI rebundles the lot into a denial. We report the panel as a panel and add only medically necessary, separately orderable tests on top of it.
Here is the full code map we manage so each case is paid to its true value — nothing rounded away, nothing left uncaptured:
| Code family / revenue stream | What it covers | What we manage |
|---|---|---|
| Surgical pathology (CPT 88300–88309) | Gross and microscopic exam billed per specimen at Level I–VI by specimen type and complexity — 88305 the highest-volume code | Correct level assignment, one unit per distinct specimen, and the 26/TC/global component for the setting |
| Special stains, IHC & ISH (88312–88377) | Histochemical special stains, immunohistochemistry 88341/88342/88344, in situ hybridization and FISH 88365–88377 | Per-specimen vs per-antibody units, single vs multiplex reporting, and separately identifiable stains captured, not absorbed |
| Cytopathology (88104–88175) | Non-gyn cytology, fine-needle aspiration, and Pap tests — manual, automated, and physician-interpreted screening | Screening vs interpretation coded correctly, FNA adequacy and the professional read billed with the technical prep |
| Clinical laboratory (80047–89398, CLFS) | Chemistry, hematology, microbiology, and immunology priced on the Clinical Laboratory Fee Schedule | Panels reported as panels, medically necessary add-ons only, QW for CLIA-waived tests, and 91 for legitimate repeats |
| Molecular & genomic (81200–81599, PLA) | Tier 1/Tier 2 molecular, MAAAs, genomic sequencing procedures, and proprietary PLA codes ending in U | LCD/MolDX medical-necessity record, registered test identifier, and NCCI stacking rules applied before submission |
| Flow cytometry & modifiers (88184–88189, 26/TC, 90/91) | Flow cytometry technical and interpretive tiers; component, reference-lab, and repeat modifiers | Marker-count tiers billed correctly; 26/TC, 90 outside-lab, and 91 repeat modifiers applied to the right lines |
Most pathology losses trace back to the same short list of failure points, and each one is preventable at the front end — before it becomes a denial or a recoupment rather than after it becomes an argument:
Multiple distinct specimens billed as one unit — or blocks billed as separate specimens
Under-captured revenue, or a downcoding recoupment for over-reported 88305 units
We assign one unit per distinct, separately identified specimen at the correct 88302–88309 level from the report
Chemistry panel unbundled into component tests
NCCI rebundling denial and improper-payment exposure on 80047/80053 and similar
We report the panel as a panel and add only medically necessary, separately orderable tests
Molecular/genomic test billed without LCD support or MolDX identifier
Medical-necessity denial on high-dollar 81xxx/PLA claims
We attach the covered diagnosis and registered test identifier and confirm the governing LCD before submission
Test performed outside the lab's CLIA certificate scope
Denial — CLIA certification and correct QW use are conditions of payment
We bill within the certificate's authorized specialties and apply QW only to approved waived tests
Reference/outside-lab and repeat tests billed without modifier 90/91
Duplicate or reference-lab denial and recoupment
We apply 90 for outside-lab work and 91 only for genuine, separately ordered repeats
Hospital-outpatient molecular specimen billed against the date-of-service rule
Denied or conflicting claim between the hospital and the performing lab
We apply the 14-day date-of-service rule so the correct entity bills Medicare for the molecular test

Pathology is a volume business run on thin per-specimen margins, and that combination punishes exactly the errors an in-house team is most likely to make.
A single coder who has to hold the specimen-count rule, the 26/TC split, the panel-bundling logic, the CLIA scope, and every MolDX LCD in their head — while a high-dollar molecular claim sits aging in a medical-necessity queue — is one resignation away from a cash-flow problem. When you outsource pathology billing services to us, that entire rulebook moves to a certified team that already runs it every day, and the fixed cost of a biller becomes a transaction-based fee that scales with your accession volume instead of your headcount.
The payoff is specific to this specialty. Labs and pathology groups that move to us stop losing revenue in the two places pathology bleeds most — miscounted specimen units and denied molecular claims — and they get that revenue back without hiring, training, or covering for anyone. You keep signing out cases; we keep the units, components, panels, and coverage records correct before the claim ever leaves your building.
Everything it takes to move a pathology case from accessioning to paid, run by one certified team instead of split across vendors:
Payer credentialing and re-credentialing with the CLIA certificate and test-menu scope confirmed and reassignment tracked, so nothing rejects on provider or lab eligibility.
Surgical-pathology levels, special stains and IHC, cytology, clinical chemistry panels, and molecular/genomic assays coded to the correct CPT, unit count, and 26/TC/global component by our certified pathology coding team.
The signed report reconciled to the accession, the correct specimen units and component applied, panels bundled, scrubbed, and filed within 24 hours.
Every denial run to root cause and appealed with the pathology report and coverage record inside the deadline, whether it's medical necessity, units, NCCI rebundling, or a reference-lab bounce.
If you'd rather keep the whole cycle under one roof, fold coding, billing, A/R, and reporting into our full revenue cycle management service, with certified coders and billers sharing the same report instead of handing claims between companies.
That single-team model is what keeps a pathology billing services company useful past the first quarter: coding and billing never drift apart, and there's one dashboard and one account manager for the whole cycle.
Revenue review
A certified pathology specialist puts a dollar figure on what your specimen-unit errors, panel unbundling denials, and aged molecular claims are costing you right now.

Choosing us isn't retaining a general biller who happens to accept lab claims. It's retaining a pathology billing company that already knows where anatomic and clinical revenue leaks and how to close it before the payer ever sees the claim:
Surgical-pathology units are assigned per distinct specimen at the right level, so you capture every payable unit without inviting an over-reporting audit.
Chemistry panels are reported as panels with only medically necessary add-ons, so NCCI doesn't rebundle your claims and reflex tests still get captured where the order supports them.
Tier 1/Tier 2, MAAA, and PLA claims go out with the LCD-supported diagnosis and the registered MolDX identifier where required, so your highest-dollar tests pay instead of denying.
Test menus are billed within your CLIA certificate scope, and the 90 reference-lab and 91 repeat modifiers are used only where the arrangement and documentation support them.
A named account manager owns your account and a live 360° dashboard shows every case, denial, and dollar — with no long-term lock-in holding you there.
That discipline holds the numbers steady:
Those figures repeat month after month rather than only in the first cycle.
A generalist learns pathology on your claims. We arrive already fluent in it — and the gap shows up directly on the remittance:
The rules shift with the setting and the test menu, and we bill each one to the detail it demands:
High-volume CLFS chemistry, hematology, and microbiology billed with panel logic, frequency limits, and client-bill versus patient-bill arrangements handled cleanly.
What decides the moneyPanel logic and frequency limits
Surgical pathology and cytology billed per specimen at the right level, with the professional-component read matched to hospital and independent-lab settings.
What decides the moneyUnit count and the matched component

Skin biopsies, special stains, and immunofluorescence billed with the correct units and component, closely aligned with our dermatology billing services.
What decides the moneyUnits and component on every stain
Definitive and presumptive drug testing and POL menus billed within CLIA scope, with QW and medical-necessity documentation kept audit-ready.
What decides the moneyStaying inside the certificate scope
Changing billers shouldn't cost you a cycle of revenue, and with us it doesn't.
We work inside your existing laboratory information system and practice-management platform, so nobody relearns a system.
Credentialing, CLIA scope review, and payer-enrollment checks run in parallel while your claims keep going out the door, and a named account manager leads the transition from day one.
Most labs and pathology groups are fully live within a few weeks.
The denial drop and the faster A/R turn up in the first cycles — not a quarter down the road.
More of every accession pays on the first submission.
Specimen units counted straight from the gross description, the professional and technical components matched to the setting, panels kept intact, and every high-dollar molecular claim built to survive medical-necessity review before it ships. Our pathology medical billing runs a 99% first-pass clean-claim rate, drives net collections near 99%, and pulls days in A/R under 25, which is what protects the thin per-specimen margins a generalist quietly erodes by billing lab work like office visits. From high-volume clinical labs to hospital-based pathology groups and molecular labs living on proprietary assays, medical billing for pathology at 247MBS makes sure nothing payable is rounded away and nothing over-reported invites an audit.

Choose the pathology billing services provider that already counts specimens, splits components, and defends molecular claims correctly — not one that learns it on your accessions.
What changes hands
Outsource pathology billing to us and the specimen-count rule, the component split, panel logic, CLIA scope, and every coverage determination stop depending on one biller's memory — they run daily on a certified team that codes every specimen, panel, stain, and molecular assay to the right unit and component, checks it against the coverage record, and files it within 24 hours.
Nothing changes in the lab; you keep your laboratory information system while we run coding, scrubbing, submission, denials, and A/R behind it. Outsourcing pathology billing services with 247MBS means cleaner claims paid faster — up to 40% fewer denials, roughly nine of ten worked denials overturned, and days in A/R under 25 — with a live dashboard showing where each dollar sits.
Pathology billing services outsourcing also swaps the fixed cost of an in-house biller for a transaction-based fee that scales with accession volume, not headcount, and strips the hiring and training overhead off your books. Start with a revenue review or call +1 888-502-0537.
