Is This Your Internal Medicine Practice?

Most internal medicine practices lose 15-30% of potential revenue without realizing it. Your coding errors, missed HCC documentation, and unclaimed CCM programs are silently draining thousands monthly.

Denial Rate Killing Cash Flow

You bill complex visits with 3-5 chronic conditions, but denials flood back. Missing HCC specificity, incorrect ICD-10 linking, preventive+E/M confusion, costing you thousands monthly.
Lost revenue: $3,000 – $8,000/month

Accounts Receivable Beyond 90

Claims sit unpaid for 60, 90, even 120+ days. Your staff spends hours on payer hold while cash flow strangles operations. You wonder when you’ll get paid for care delivered months ago.
Cash flow strain: 45-90 days delayed

Revenue Left on the Table

Your practice qualifies for CCM, TCM, and AWV programs worth $25K-$50K annually, but complex documentation requirements keep you from billing. That’s $2,000-$4,000 monthly you’ll never see.
Missed opportunity: $2,000 – $4,000/month

Staff Turnover & Burnout

Your billing team is overwhelmed. Training takes months, mistakes are costly, and turnover is constant. Every resignation means starting over, while paying $80K-$120K per biller annually.
Annual cost: $80,000 – $120,000 per biller

Why MedStates Is Different From Other Internal Medicine Billing Companies

Many internal medicine billing companies rely heavily on automation and AI-driven workflows that miss the documentation nuances behind chronic care management, HCC coding, modifier 25 billing, and complex multi-condition encounters. At MedStates, our internal medicine billing services are driven by experienced human billers and AAPC-certified specialists — not AI-generated coding decisions or automated claim handling. Every claim is reviewed by professionals who understand internal medicine documentation, payer behavior, Medicare Advantage requirements, and chronic disease coding complexity. This hands-on approach helps identify missed reimbursement opportunities, reduce preventable denials, improve coding accuracy, and ensure your practice receives the attention and expertise that automated billing systems often fail to provide.

We will tell you exactly how much revenue your practice is losing and how our internal medicine medical billing services can recover that.

Frequently Asked Questions

Medstates Medical Billing Services

How Does HCC Coding Affect Reimbursement?

HCC coding affects Medicare Advantage reimbursement by assigning risk scores based on documented chronic conditions. Accurate HCC documentation helps internal medicine practices improve RAF scoring, support compliant risk adjustment, reduce revenue loss, and reflect patient complexity more accurately.

Can Internal Medicine Bill CCM and AWV Together?

Yes, internal medicine practices can bill Chronic Care Management and Medicare Annual Wellness Visits together when CMS documentation, consent, and billing requirements are met. These services are separately reimbursable because they address different aspects of patient care and preventive management.

How Are Preventive Visits Billed in Internal Medicine?

Preventive visits are billed using preventive medicine CPT codes or Medicare wellness visit codes depending on payer rules and patient eligibility. If additional medical conditions are evaluated during the visit, a separate E/M service with modifier 25 may also be billed.

What Is RAF Scoring in Internal Medicine?

RAF scoring measures patient health complexity in Medicare Advantage plans using documented HCC diagnoses. Accurate RAF scoring helps internal medicine practices improve reimbursement, support value-based care programs, maintain compliance, and ensure chronic conditions are properly captured and reported annually.

How quickly can you start handling our internal medicine billing?

We onboard in 7-10 days. Most practices see their first clean claims submitted within 2 weeks. During onboarding, we handle EHR integration, credentialing verification, and payer setup.

Do we need to change our EHR system to work with you?

No. We use all major EHR systems, Epic, Cerner, Athenahealth, eClinicalWorks, NextGen, and 40+ others. No software changes, no data migration, no disruption to your workflow with our internal medicine billing services.

What makes internal medicine billing different from other specialties?

Internal medicine requires expertise in multi-morbidity coding (3-5 chronic conditions per visit). HCC risk adjustment for Medicare Advantage, complex E/M documentation, and care management programs like CCM, TCM, and AWV.

How do you handle state-specific Medicaid variations?

Our compliance team tracks all 50 state Medicaid programs plus hundreds of MCO policies. We monitor LCD/NCD updates monthly and adjust billing protocols automatically. You never worry about state-specific variations or regulatory changes, we handle every detail.

What if we're already using another internal medicine billing company?

Our internal medicine billing service makes switching seamless. We audit your current performance, identify gaps, handle all transition logistics, and maintain cash flow throughout.
