How We Streamline Internal Medicine Billing for Your Practice

We specialize in providing seamless and error-free internal medicine medical billing services with our deep knowledge and expertise. Our team comprises skilled medical billers/coders, A/R specialists, credentialing experts, insurance experts, and patient accounts representatives, among others. They possess deep expertise in CPT-10/ICD coding, HIPAA regulations, and HCPCS Level II Codes. We streamline your internal medicine billing requirements through our seamless and efficient billing services. Here's how we accomplish this:

  • Implement billing software integrated with EHR, EMR, and EDI capabilities to digitize billing processes, like electronic claims submission, electronic payments posting, and patient statements. 
  • Capture comprehensive patient details (demographics, medical history, and physician referral information) and insurance payer details (coverage type, prior authorization status, effective dates, expiration dates, and claims address) to ensure claims processing with minimal errors.
  • Manage multiple internal medicine billing models (value-based billing, capitation billing, fee-for-service billing, time-based billing, hybrid models, etc.) to align with global healthcare consumerism trends.
  • Maintain precision while assigning CPT and ICD-10 codes within 99202 – 99215/ 99202 – 99205/99211 – 99215/ 99242 – 99245 ranges to capture aspects like outpatient, office, or emergency department visits, preventive services, chronic disease management, and vaccinations.
  • Cover billing services for various procedures of internal medicine like diagnosis, treatment, and prevention of diseases affecting the respiratory, cardiovascular, digestive, endocrine, and immune systems, infectious diseases, mental health issues, various types of cancer, etc. 
  • Stay updated with any revisions in the fee schedules or claims filing guidelines for insurance payers, including Medicare, Medicare Advantage Plans (Part C), Medigap, FEHBP, and private insurance payers like UnitedHealth, Humana, etc.
  • Resolve claims disputes in EOBs and initiate the appeals process to gain maximum reimbursement for the services rendered.
  • Calculate out-of-pocket expenses (deductibles, copayments, coinsurance, etc.) with the help of EOB and inform patients about their financial responsibility.
  • Monitor and analyze key internal medicine billing metrics, such as clean claims rate, average days in AR, claims denial rate, charge entry lag, average reimbursement per encounter, cost per claims processed, etc.
