Case Study: How We Recovered 45% Revenue for a Gastroenterology Practice

A high-volume gastroenterology practice in New York was facing revenue challenges due to common but costly billing issues. Errors in colonoscopy billing, delays in prior authorizations, and inconsistent documentation were resulting in claim denials, underpayments, and reimbursement delays.

After partnering with MBW RCM, the practice saw a 45% revenue increase within six months—alongside faster collections, fewer errors, and better financial performance.

Client Profile

  • Location: New York, USA

  • Specialty: Gastroenterology

  • Monthly Patient Volume: ~1,200

  • Monthly Billing Volume: $500,000

  • Collections Before RCM Optimization: $300,000/month

Despite a steady patient load, the practice was struggling to collect on time due to inefficient revenue cycle management (RCM) and lack of specialty-focused billing support.

Challenges in  Behavioral & Mental Health Billing

  1. High Claim Denial Rates

    Frequent rejections due to coding errors, missing documentation, and incorrect modifiers—especially for endoscopy and ERCP billing—led to delayed payments.

  2. Complex Gastroenterology Coding

    Procedures like colonoscopy with biopsy, upper GI endoscopy, and ERCP require precise CPT and ICD-10 coding. Incorrect or inconsistent use caused claims to be rejected or underpaid.

  3. Authorization Delays

    Manual and unstructured prior authorization processes resulted in treatment delays and revenue bottlenecks.

  4. Unstandardized Clinical Documentation

    Providers used different templates and formats, leading to missing elements required for successful claims submission and compliance.

  5. Insurance Eligibility Issues

    Lack of real-time insurance verification meant services were often rendered before confirming coverage, increasing denial risk.
