# Bookkeeping and billing for clinical laboratories

LedgerBPO provides bookkeeping for clinical laboratories: a named, dedicated accountant who posts LIS and billing-system exports to QuickBooks Online or Sage Intacct, reconciles Medicare, Medicaid, commercial and client-bill receipts to the bank, tracks reagent and send-out costs per test line and closes the books every month under a two-accountant review. High accession volumes stay in your systems; the ledger stays clean.

## Clinical labs accounting challenges

1. 01
### Thousands of small claims, one ledger
A mid-sized lab can process thousands of accessions a month, each producing several CPT lines that are paid at Clinical Laboratory Fee Schedule or contract rates. Posting from bank deposits hides adjustments; posting from the billing system needs a disciplined export routine.
2. 02
### Fee-schedule pressure squeezes margin
Under PAMA, Medicare's Clinical Laboratory Fee Schedule is reset from private-payer rate reporting, with annual reductions capped at 15 percent when cuts apply. A lab that does not know its cost per test by line cannot tell which tests still cover their reagents.
3. 03
### Three revenue streams, three aging reports
Labs bill third-party payers, bill clients such as physician groups and nursing facilities on monthly invoices, and bill patients for deductibles and non-covered tests. Each stream has different terms and follow-up rules, so one blended AR figure hides the problem stream.
4. 04
### Reagent rental and send-outs blur cost of goods
Analyzers are often placed under reagent rental agreements where the instrument cost is folded into per-test reagent pricing, and reference-lab send-outs arrive as a single monthly invoice. Without coding those bills to test lines, gross margin per test is a guess.
5. 05
### Medical-necessity denials arrive late
Medicare pays covered clinical diagnostic lab tests at 100 percent under Part B with no patient coinsurance, but tests that fail an LCD or NCD medical-necessity rule are denied after the work is done. Denied accessions have to be written off or rebilled, and the ledger must show which.

## What we handle for clinical laboratories

### Billing-system and LIS exports posted

Your accountant pulls monthly charge, adjustment, cash and AR reports from XIFIN, TELCOR or your billing platform, and accession counts from the LIS, and posts them to the ledger by payer class and test line. Patient detail stays in your systems.

### Client-bill invoicing and follow-up

Monthly invoices to physician offices, nursing facilities, employers and other labs are prepared from LIS volumes at contracted rates, sent under your brand, and followed up on a DunningDesk cadence. Disputed line items are worked from the accession list.

### Deposits matched to posted cash

Medicare MAC EFTs, Medicaid, commercial ERAs, client checks and patient card payments are matched to posted batches under our ReconBot workflow. Unmatched items sit on an exception log with a name and a date.

### Cost per test by line

Reagent, consumable, send-out, courier and proficiency-testing costs are coded to chemistry, hematology, molecular, toxicology or pathology lines. Reagent rental agreements are tracked so instrument cost is visible.

### Payroll and shift pay posted by site

Phlebotomist, technologist and courier payroll from Gusto, ADP or Paychex is posted by draw site and department, with differentials and on-call pay reconciled to the provider reports.

### One team for claims and books

When our sister brand SS Support Network handles lab claims and denials, the same team lead reconciles billed, adjusted and collected figures to the ledger. Every close passes Two-Tier Review before it reaches you.

## Clinical labs compliance notes

### CLIA

Every lab that tests human specimens must hold a CLIA certificate matched to the complexity of its testing, renewed on a two-year cycle with fees based on test volume. We record certificate fees, proficiency-testing subscriptions and inspection-related costs as compliance expenses and keep renewal dates on the close calendar. Certification and inspection readiness stay with your lab director.

### Payer rules and PAMA

Medicare pays lab tests from the Clinical Laboratory Fee Schedule, commercial payers pay contract rates, and both apply medical-necessity and frequency rules that produce denials. PAMA private-payer rate reporting also falls on applicable labs in reporting years. We keep revenue, adjustments and denials in separate accounts so your billing team and CPA can see each effect.

### HIPAA

Remittances, client invoices and LIS exports carry patient identifiers and test names. Our staff are HIPAA-trained, we sign a BAA, all access is logged with MFA, and exports are handled inside your systems and our portal rather than on local drives.

### Anti-kickback and EKRA

The federal Anti-Kickback Statute and the Eliminating Kickbacks in Recovery Act restrict how labs pay marketers and how they price or discount services for referral sources. We record sales compensation and client discounts exactly as your compliance counsel has approved them, and flag any arrangement that looks volume-based so it can be reviewed. We do not give legal advice.

## KPIs we report

| KPI | Why it matters |
| --- | --- |
| Revenue per accession by payer class | A falling figure signals fee-schedule cuts, payer-mix drift or unbilled tests before the P&L shows it. |
| Cost per test by test line | Reagent rental and send-out costs decide which lines are worth keeping at current rates. |
| Client-bill invoices sent by the third business day | Client AR is the one stream you control fully, and late invoices become late payments. |
| Denied and written-off accessions as a share of billed | The trend shows whether medical-necessity and eligibility checks at intake are working. |
| Books closed within five business days of month-end | Lab owners, lenders and billing managers need one agreed set of numbers early each month. |

Healthcare billing, credentialing and call-centre operations are delivered with our sister brand [SS Support Network](https://sssupportnetwork.llc/). LedgerBPO keeps the books and billing reconciled to it.

## Frequently asked questions

### Do you handle laboratory claims billing?

LedgerBPO handles the books, client-bill invoicing, patient statements and the reconciliation of billing-system activity to the ledger and bank. Claims submission, denials and appeals to Medicare and commercial payers are handled by your billing team or by our sister brand SS Support Network. When both are with us, one team lead reconciles claims data against the ledger every month.

### Can you work with our LIS and billing platform?

Yes, through their standard reports and exports. We use monthly charge, adjustment, cash and AR reports from XIFIN, TELCOR or your billing system and accession volume reports from Orchard, Sunquest, SCC Soft or another LIS. We do not modify orders, results or claim data. If your platform has a general-ledger export, we map and test it.

### How do you separate third-party, client-bill and patient revenue?

Each stream has its own revenue, adjustment and AR accounts, and each is aged separately. Third-party figures come from the billing system, client-bill figures from the invoices we prepare, and patient balances from statements. The three agings are tied to the ledger every month so you can see which stream is slowing.

### How do you track the cost of reagent rental agreements?

Reagent rental invoices are coded to the test line the analyzer serves, and the agreement terms, minimum volumes and per-test pricing are recorded so the effective instrument cost is visible. When a lab also owns analyzers outright, those are capitalized and depreciated monthly. The result is a cost per test that includes instruments, not just consumables.

### What does the monthly package include for a lab?

A P&L by test line and site, a balance sheet with reconciled AR by stream, an accession and revenue-per-accession summary, a client-bill aging, a denial and write-off summary and a short note on what moved. The month-end close service page describes the CloseTrack checklist behind the package.

### Is patient information protected with a remote team?

Yes. Staff are HIPAA-trained, we sign a BAA, every login uses MFA and access to your billing platform and bank feeds is read-only wherever possible. Exports are worked inside your systems and our LedgerDesk portal, never stored on local machines. Our security page lists the complete control set.
