Most U.S. hospitals and clinics lose revenue to coding gaps they never see. Charts sit uncoded while DNFB climbs, specificity gaps trigger downstream denials, and E/M levels drift conservative because nobody has time to query the physician. The AAPC and AHIMA both document that coding-related issues drive 15% to 20% of initial denials. RCMGen’s medical coding services close every one of those gaps end to end.
Our certified coders, holding CPC, CCS, COC, CIC, and specialty credentials, code daily across
Medicare, Medicare Advantage, Medicaid, and every major commercial payer. As a result,
our coding workflow consistently delivers 95%+ audited accuracy with under 24-hour turnaround,
keeping discharged-not-final-billed days below 3 against the 5-to-8-day pattern tracked by HFMA
From the moment documentation closes to the day the coded claim drops to billing, our medical coding workflow runs continuously. Our coding teams assign codes within hours of chart completion, route ambiguous documentation through compliant physician queries, and audit a defined sample of every coder’s output weekly. Moreover, every chart moves through specialty-specific coding desks staffed by credentialed coders, so each code assignment is backed by current guidance from CMS, the AMA, and AHA Coding Clinic rather than guesswork.
ICD-10-CM and ICD-10-PCS coding
Diagnosis and inpatient procedure coding to the highest documented specificity, validated against current CMS guidelines and quarterly code updates.
CPT and HCPCS procedure coding
Surgical, diagnostic, and ancillary procedure coding with correct modifier application backed by AMA CPT guidance and NCCI edit logic.
E/M leveling and audits
Evaluation and management levels assigned under current 2021+ MDM and time rules, with under-coding and over-coding both flagged.
HCC and risk adjustment coding
Hierarchical condition categories captured and validated for Medicare Advantage and ACA risk- adjusted populations with RADV-ready documentation.
Coding audits and compliance reviews
Scheduled and targeted audits sampling every coder and provider, scored against CMS, OIG, and payer-specific documentation standards
CDI and physician query feedback
Recurring denial patterns are escalated weekly to your front-end teams, with documented edits, training, and workflow changes that stop denials at the source.
Medical coding benchmarks we operate against
The dashboard below shows the U.S. industry benchmarks our medical coding workflow is engineered to outperform, sourced from AAPC, AHIMA, and HFMA. Each indicator marks the median, with the blue zone showing our internal target range across hospital, clinic, and physician group accounts.
Benchmark sources: AAPC Audit Services data 2025, AHIMA coding productivity studies 2025, HFMA MAP Keys 2025.
Coding desks we run daily
Coding behaves differently depending on the care setting and specialty. Therefore, we operate dedicated coding desks for the nine areas that carry the largest documentation complexity and denial exposure across U.S. hospitals, clinics, and physician groups. Each desk is staffed by credentialed specialty coders working against current 2026 guidance from CMS, the AMA, and AHA Coding Clinic.
Inpatient DRG coding (ICD-10-PCS)
Principal diagnosis selection, CC and MCC capture, and DRG validation coded against current MS-DRG and APR-DRG logic.
Outpatient and ASC coding
APC assignment, surgical groupers, device and implant coding, and OPPS edit clearance for hospital outpatient and surgery centers.
Professional fee and E/M coding
Office, inpatient, and telehealth E/M leveling under 2021+ MDM rules, with split and shared visit logic applied correctly.
Emergency department coding
Facility and professional ED levels, critical care time, procedures, and observation coding coordinated for clean split billing.
Surgical and operative note coding
Complex multi-procedure operative sessions coded with correct sequencing, modifiers, and global package logic by surgical specialty
Radiology and imaging coding
Diagnostic and interventional radiology, contrast logic, and component billing coded with correct professional and technical splits.
Oncology and infusion coding
Chemotherapy administration hierarchies, drug units, and treatment plan coding validated against payer medical policies.
Behavioral health coding
Psychotherapy time rules, add-on codes, and state Medicaid behavioral billing requirements applied across all programs.
HCC risk adjustment coding
Chronic condition capture, recapture validation, and RADV-ready documentation review for risk- adjusted populations.
Inside a single coding work cycle at RCMGen
Coding work does not pause for nights, weekends, or U.S. federal holidays. As a result, every 24 hours your charts move through the cycle below, anchored to Central Time so your HIM team always knows what to expect when they log in.
Overnight chart intake and assignment
Completed documentation is pulled from your EHR, charts are routed to the correct specialty coding desk, and priority accounts are flagged for first-pass coding.
Coding production and quality review
Specialty coders assign codes, QA reviewers sample output, and your coded chart ledger with DNFB status is delivered before 8 AM EST every weekday.
Physician queries and CDI feedback
Compliant queries route to providers, documentation gaps are escalated to CDI teams, and coding clarifications resolve during U.S. business hours.
Audit sampling and next-day prep
Weekly audit samples are scored, education items are documented, KPI dashboards refresh, and tomorrow’s chart queues are prioritized for the overnight team.
Why hospitals and clinics choose RCMGen for medical coding services
Most coding vendors compete on price per chart. RCMGen competes on audited accuracy, turnaround speed, and DNFB compression. Our coding team is built around senior, credentialed specialty coders, not generalist production staff. Additionally, our internal Intelligence Hub tracks quarterly code updates, NCCI edits, and payer policy changes inside a 72-hour refresh window, so the chart you receive coded on Friday reflects the guidance published on Tuesday.
Furthermore, we code natively inside Epic, Oracle Health (Cerner), Athenahealth, eClinicalWorks, NextGen, Meditech, AdvancedMD, Allscripts, and dozens more, so there is zero disruption to your existing HIM workflows.
