Medical Billing Services
Medical billing is the mechanical core of the revenue cycle: turning a clinical encounter into a correctly formatted claim, getting it in front of the right payer the first time, and posting the payment accurately when it comes back. Flint RCM handles charge entry, multi-layer claim scrubbing, electronic submission, and payment reconciliation for practices that want fewer rejections and faster, more predictable reimbursement — without hiring and managing a billing team in-house.
Built for practices like yours.
- Practices currently billing in-house and losing time to rejected or denied claims
- Groups switching billing vendors after inconsistent turnaround or poor communication
- New practices that need a billing workflow built correctly from day one
- Multi-provider groups whose claim volume has outgrown a single in-house biller
What this fixes.
- Claims rejected at the clearinghouse before they even reach the payer
- Denials caused by avoidable front-end errors — typos, mismatched IDs, missing modifiers
- Slow, inconsistent cash flow because claims sit before submission
- No clear picture of which claims are clean, which are stuck, and why
The work, in practice.
We handle the full billing workflow from charge entry through payment posting, with structured scrubbing at every step so problems get caught before a claim leaves the building — not after a denial comes back.
- Charge entry and capture from clinical documentation
- Multi-layer claim scrubbing: CPT/ICD-10 pairing, modifier accuracy, payer-specific formatting
- Electronic claim filing (837) through your existing clearinghouse
- ERA/EOB payment posting (835), reconciled against your fee schedule
- Secondary and tertiary claim filing where coordination of benefits applies
- Patient statement generation for remaining balances
- Daily charge entry and claim creation
- Pre-submission claim scrubbing against payer edits
- Electronic claim submission via your clearinghouse
- Payment posting and fee-schedule reconciliation
- Secondary/tertiary claim filing
- Patient statement generation
Our process, start to finish.
Charge Capture
Encounter data and clinical documentation are turned into charges the same day claims are ready to go out, not batched and delayed.
Claim Scrubbing
Every claim is checked against CPT/ICD-10 pairing rules, modifier logic, and payer-specific formatting requirements before submission.
Electronic Submission
Clean claims are filed electronically through your existing clearinghouse as an 837 transaction, so there's no new system for your team to learn.
Payment Posting & Reconciliation
ERAs are posted against the fee schedule as they arrive, with variances flagged rather than silently absorbed.
Exception Handling
Anything that doesn't post cleanly — a rejection, an underpayment, a denial — is routed into AR follow-up rather than left sitting.
- Clean claim rate (first-pass acceptance)
- Days from charge entry to submission
- Rejection and denial rate by cause
- Days in AR and collection trends
Common denials we watch for.
Most billing-side denials trace back to a handful of recurring causes. We build claim scrubbing around exactly these patterns rather than treating every denial as a one-off.
- CO-16 — claim lacks information needed for adjudication (missing or invalid data field)
- CO-18 — duplicate claim or service, often from resubmission timing issues
- CO-11 — diagnosis code inconsistent with the procedure billed
- CO-29 — timely filing limit exceeded
- CO-97 — service bundled into another already-paid procedure
- Required-field and payer-format validation built into pre-submission scrubbing
- Claim status tracked from submission through adjudication to catch resubmission timing issues
- CPT/ICD-10 pairing checked against payer edits before a claim goes out
- Claims aged and prioritized so nothing sits long enough to hit a filing deadline
- Bundling edits checked against current NCCI pairs before submission
Rules change by specialty — so does our approach.
Medical Billing looks different depending on what you bill. A few specialties where this shows up most:
Works inside the systems you already use.
We integrate with your existing EHR and practice management system rather than asking you to switch platforms — including AdvancedMD, Tebra, athenahealth, eClinicalWorks, DrChrono, NextGen, and Epic. Claim data flows from the system you already use, so onboarding doesn't mean retraining your front desk.
Medical Billing, answered.
We work through your existing clearinghouse wherever possible. There's usually no reason to disrupt a connection that's already set up and working.
We map open claims and work-in-progress during onboarding so nothing gets dropped in the handoff — claims already submitted continue to be tracked through resolution.
Yes. Coordination of benefits and secondary/tertiary claim filing are part of standard billing service, not a separate add-on.
Charge entry and scrubbing happen on a daily cycle, so clean claims typically go out within a day or two of the encounter being documented.
