Medical Billing Services Group (MBSG) provides outsourced medical billing services to US physician practices that want a defined, accountable billing operation without hiring and managing one in-house. Outsourcing replaces an internal billing department — or a patchwork of part-time staff, spreadsheets, and clearinghouse logins — with a dedicated team that owns your revenue cycle from charge capture through payment posting, and reports to you on a predictable cadence.
Direct answer: Outsourced medical billing services move your day-to-day billing work — eligibility checks, claim submission, denial follow-up, and payment posting — to an external team working inside your practice management system, with defined reporting, named accountability, and a documented 60–90-day transition plan for your practice.

Scope and suitable buyers
Outsourced billing fits practices that have outgrown their current setup: a solo biller who is overwhelmed, a practice manager doing billing on the side, turnover that left claims aging unattended, or growth that the internal team cannot absorb. It also suits practices that want predictable billing operations without the cost and risk of recruiting, training, and retaining billing staff.
Outsourcing does not fit every practice. If your billing is already stable, your denial rate is low, and your staff handles volume comfortably, an audit or targeted support such as denial management may be more appropriate than a full outsourcing engagement. MBSG’s services overview describes how the pieces fit together so you can choose the right level of support. The model works across specialties; practices that want a deeper diagnostic before committing can review the medical billing audit engagement.
Workflow
The operating model is simple: a named team at MBSG works inside your systems, following a documented workflow that you can inspect at any point.
Inputs, quality checks, escalation and reporting
Inputs. MBSG receives your charge data from your practice management system or EHR, eligibility information, payer remittances (ERAs and paper EOBs), and patient-payment records. You provide system access and the source documents; MBSG does the work inside your environment. Nothing is re-keyed into a separate MBSG system that you cannot see.
Quality checks. Every claim passes a pre-submission scrub: patient demographics, eligibility status, coding-to-diagnosis linkage, and payer-specific rules are verified before the claim goes out. Claims are submitted electronically through your clearinghouse, and acknowledgments are tracked so rejected submissions are caught the same day.
Escalation. Problems that MBSG cannot resolve without you — credentialing gaps, missing documentation, a payer policy decision that affects the whole practice — are escalated to a named contact at your practice with a clear description of what is needed and by when. Escalations are tracked in the monthly report so nothing disappears.
Reporting. You receive reporting on a defined cadence: a weekly operations snapshot (submissions, rejections, payments posted, denials worked) and a monthly management report with aging analysis, denial trends, and action items. The data belongs to you — reports, exports, and working files are delivered in formats you can keep and audit independently.
What rejection and denial mean in your workflow
Two terms cause confusion, and the difference matters because each requires a different response:
- Rejection means a claim was returned before adjudication — typically by the clearinghouse or the payer’s front-end system — because of a formatting error, missing information, or invalid data. A rejected claim has not been adjudicated, so there are no appeal rights involved; it is corrected and resubmitted.
- Denial means the payer adjudicated the claim and made a decision not to pay it (in whole or in part). A denial comes with appeal rights, and the response is a formal appeal or reconsideration with evidence, not a resubmission.
MBSG tracks both separately in reporting because the corrective actions are different: rejections point to data-quality problems at submission, while denials point to coding, medical-necessity, or contract issues that need clinical or payer-policy work.

Included and excluded work
Included in outsourced billing: eligibility verification, claim submission and rejection correction, payment posting, payer A/R follow-up, denial management and appeals, patient statements and lawful patient-balance workflows, monthly management reporting, and credentialing-status monitoring (flagging when a provider’s enrollment lapses would block payment).
Excluded unless separately agreed: credentialing and payer enrollment itself (see credentialing and payer enrollment for a dedicated engagement), legal or licensed debt-collection activity, clinical coding decisions that require provider judgment, and historical A/R older than the agreed transition window, which is handled as a separate legacy A/R project. Exclusions are documented in the engagement terms so expectations are set before work begins.
Onboarding and systems
Transition follows a 60–90-day plan with named responsibilities on both sides.
What your practice provides: access to your practice management system, EHR, and clearinghouse; credentialing and payer-enrollment information for every billing provider; historical claims data and an A/R export; a decision on legacy A/R (who works it, and what gets written off); and a named internal contact who can answer operational questions during setup.
What MBSG does: configures team access and permissions; establishes payer connectivity through your clearinghouse; maps your current workflows (who does what today, where the handoffs are, where claims stall); runs a baseline report on your current A/R, denial rate, and clean-claim performance before changing anything; and phases in responsibility — typically eligibility and submission first, then A/R follow-up and reporting — so there is no gap in coverage during the switch.
During onboarding you keep full visibility: MBSG works inside your systems, and you can see every action taken, claim by claim.
Pricing factors
Outsourced billing is typically priced as a percentage of net collections or as a fixed monthly fee; the factors that move price are claim volume, specialty complexity, the state of your current A/R (cleanup work costs more than steady-state work), and which modules you include — full outsourcing versus billing-only with in-house coding, for example. The denominator of a percentage-of-collections fee matters: it should be defined as collections actually received, not billed charges. A full worked example of the denominator concept is covered on the medical billing pricing page.

FAQs
Does outsourcing mean MBSG owns our data or our systems?
No. Your practice management system, your payer enrollments, and your data remain yours. MBSG works inside your systems with assigned credentials, and everything produced — reports, exports, working notes — is delivered to you in formats you can keep.
What happens if we want to end the engagement?
Transition assistance is part of the operating model: on termination, MBSG hands over all documentation, open A/R notes, workflow mappings, and in-flight appeals so your next arrangement — in-house or another vendor — picks up without a coverage gap. Specific notice periods and terms are documented in your services agreement.
Will our staff need to learn new software?
No. MBSG works inside your existing practice management system, EHR, and clearinghouse. Share your systems during onboarding — we confirm compatibility with your setup before work begins.
How is outsourced billing different from hiring a biller?
A single in-house biller is a single point of failure — vacations, turnover, and sick leave all stop your cash flow. An outsourced team provides coverage continuity, defined reporting, and escalation structure. The trade-off is that day-to-day proximity is lower, which is why the reporting cadence and a named practice contact matter.
Can we outsource billing but keep coding in-house?
Yes. Coding-only support is available separately (see medical coding services), and integrated billing-and-coding is described on the medical billing and coding services page. The engagement scope is set during onboarding.
