Medical Billing Services Group (MBSG) offers medical coding services as a separately purchasable engagement — coding from your clinical documentation, coding QA and audits of your in-house coders, documentation gap feedback to your providers, and specialty coding support — without requiring you to buy billing alongside it.
Direct answer: Medical coding services provide accurate ICD-10-CM, CPT, and HCPCS coding from clinical documentation, plus coding audits and documentation feedback — available as a standalone engagement or as coding QA layered over an in-house coding team, with NCCI and payer-policy checks on every encounter.

Scope and suitable buyers
Standalone coding suits practices that handle billing well in-house but need coding support: a practice whose biller is not a trained coder, a group whose providers code their own visits and want an independent check, or a practice that wants its in-house coders audited by an outside eye. It also suits practices preparing for a payer audit, where a pre-emptive coding review reduces exposure.
If you want coding and billing under one accountable team — where the people who code the claim also submit it and work the denial — that is the integrated model described on the medical billing and coding services page. This page covers coding bought on its own. See the services hub for every module, and the specialties hub for specialty context. For a deeper diagnostic engagement beyond the free audit, see medical billing audit.
A note on the keyword phrase “certified medical coding services”: it appears here only as a search term. MBSG does not claim that its coders hold specific certifications; coder qualifications are not stated here until verified — never invented.
Workflow
Inputs, quality checks, escalation and reporting
Inputs. MBSG codes from your encounter documentation in the EHR — the clinical note is the source of truth. You provide documentation access, your specialty’s coding conventions, and payer policy references. Coding is never done from a charge ticket alone when the note is available.
Quality checks. Coded encounters are checked against current code sets — ICD-10-CM (FY2027 codes effective October 1, 2026; source: CMS ICD-10 codes, last reviewed 2026-10-07), CPT, and HCPCS Level II — with National Correct Coding Initiative (NCCI) edits applied per the CMS NCCI Medicare Policy Manual (source: CMS NCCI policy manual, last reviewed 2026-10-07). Modifier selection, unit counts, diagnosis specificity, and diagnosis-to-procedure linkage are verified on every encounter.
Coding QA and audits. For practices with in-house coders, MBSG audits a defined monthly sample of encounters against the documentation: code selection accuracy, modifier use, unspecified-code usage where specificity exists, and NCCI compliance. Findings are reported with the encounter references and trended month over month so improvement is measurable. Audit deliverables are described as illustrative samples when shared — they illustrate format, not client data.
Documentation gap feedback. When notes do not support the codes the visit requires, the gap is documented as specific, actionable feedback for the provider — which element is missing, and what documentation would support it. Recurring themes are summarized periodically so providers see patterns, not just one-off flags.
Escalation. Coding questions that require clinical judgment — ambiguous documentation, conflicting note elements — are returned to the provider or your coding lead with the specific question, rather than guessed at. Turnaround expectations for coded-encounter delivery are set in your agreement.
Reporting. Weekly coding volume and query status; monthly audit findings with accuracy trends and documentation themes. Reports are written for practice leadership, not just for coders.

Included and excluded work
Included: coding from clinical documentation (ICD-10-CM, CPT, HCPCS), coding QA review of in-house-coded encounters, monthly coding audits of a defined sample, documentation gap feedback to providers, specialty coding support, NCCI and payer-policy edit checks, and monthly coding reports.
Excluded unless agreed: claim submission and billing workflows (see outsourced medical billing services or the integrated medical billing and coding services page), credentialing and payer enrollment, clinical determinations that belong to the provider, and legal or licensed debt-collection activity.
Onboarding and systems
What your practice provides: EHR access for documentation review, your current coding conventions and specialty references, a named contact for coding queries (a provider or lead coder), and a baseline encounter sample if you want the starting audit to reflect recent work.
What MBSG does: establishes the coding QA standard for your specialty, configures NCCI and payer-policy checks, agrees the audit sample size and cadence with you, runs a baseline coding audit on recent encounters before routine work begins, and phases in over the 60–90-day transition — baseline audit first, then routine coding or QA volume.
Pricing factors
Coding-only pricing depends on encounter volume, specialty complexity (procedure-heavy specialties require more coding time per encounter than evaluation-and-management-heavy ones), whether you need full coding or QA review of in-house work, and audit sample size. Turnaround requirements also move price — faster turnaround costs more. Turnaround expectations are confirmed during scoping. How percentage-of-collections fees are defined is explained on the medical billing pricing page.

FAQs
Can you code for our specialty?
Specialty coding support is part of the service; supported specialties are confirmed during scoping against your encounter types and code sets. Tell us your specialty in the contact form or the free billing audit request.
Do you replace our in-house coders or audit them?
Either. MBSG can code your encounters outright, or QA and audit your in-house coders’ work on a monthly sample. Many practices start with an audit to see where they stand.
What is the difference between coding QA and a coding audit?
QA is the ongoing check applied to encounters as they are coded — every encounter, every time. An audit is the periodic deep review of a defined sample against documentation, with findings reported and trended. This service provides both.
What turnaround can we expect?
Turnaround expectations are confirmed during scoping based on your volume and specialty. It is documented in the engagement terms rather than promised here.
Are your coders certified?
MBSG does not claim certifications it has not verified; qualifications are shared during scoping once confirmed and documented.
