PGM Billing: The Gastroenterology Medical Billing Company
The field of gastroenterology demands specialized billing expertise. From diagnostic endoscopies to complex GI procedures, accurate and compliant CPT and ICD-10 coding is essential for timely reimbursements and financial stability. At PGM Billing, we provide comprehensive gastroenterology coding and billing solutions tailored to the unique needs of GI specialists.
Our end-to-end services — from claim submission and denial management to payer compliance and reporting — are designed to optimize every stage of your gastroenterology revenue cycle. Whether you’re using a legacy system or seeking a cutting-edge GI billing software, PGM helps you streamline your process, reduce errors, and boost revenue.
Why Gastroenterology Billing and Coding Is Exceptionally Complex
One of the most significant challenges in GI billing services lies in the wide variability of reimbursement protocols among insurance payers. This is particularly true when billing for high-volume and sometimes high-complexity procedures such as colonoscopies, endoscopies, biopsies, and advanced GI diagnostics. Each payer maintains its own unique rules on how procedures must be coded, what documentation is required, and how services are reimbursed. For instance, some insurers fully reimburse for bundled GI procedures, while others reduce payment or require separate authorizations, creating confusion and potential payment delays.
Without in-depth knowledge of commercial and federal payer-specific rules, practices risk revenue loss from denials, underpayments, or billing errors. These issues not only affect cash flow but can compromise long-term financial sustainability.
Navigating Medicare Requirements in Gastroenterology Medical Billing
For GI practices that accept Medicare, the complexities increase. Billing for Medicare involves highly specific coding guidelines, strict bundling rules, and frequent regulatory updates. Services such as diagnostic colonoscopies and therapeutic interventions are subject to unique documentation and reimbursement thresholds under CMS regulations.
Failure to comply with Medicare’s requirements can lead to denied claims, compliance audits, and potential penalties. That’s why many practices rely on expert GI medical billing companies like PGM to ensure every claim is submitted accurately, compliantly, and on time.

Comprehensive Gastroenterology Billing and Coding Services by PGM
At PGM, we specialize in delivering end-to-end GI billing services designed to ensure full compliance, reduce denials, and maximize revenue. Our team understands the intricacies of GI medical billing, helping practices navigate complex payer rules and streamline GI revenue operations for stronger financial outcomes. Whether you’re an independent GI specialist or part of a larger group practice, outsourcing your GI medical billing services to PGM means gaining a partner committed to accuracy, transparency, and consistent results.
GI Procedure Billing and Coding
Billing for gastrointestinal procedures such as colonoscopies, upper endoscopies (EGDs), polyp removals, and capsule endoscopies requires exact coding and thorough documentation. PGM ensures proper use of CPT and ICD-10 codes to reflect the service provided, its medical necessity, and any related diagnoses. We account for payer-specific rules on frequency limits, pre-authorizations, and bundling, helping to prevent common revenue-draining mistakes.
Gastroenterology CPT Coding Expertise
Accurate CPT coding is at the core of effective, accurate gastroenterology coding and billing that lead to clean claims and correct, timely payments. With numerous procedure variations and diagnostic complexities, even minor coding errors can lead to significant revenue loss. PGM’s certified coders are experts in applying the correct CPT codes for services such as diagnostic colonoscopy (45378), diagnostic upper GI endoscopy (43235), colonoscopy with polypectomy (45385), and wireless capsule endoscopy (91110).
Modifier Management for Complex GI Cases
Modifier usage plays a critical role in GI medical billing when multiple services are performed in the same session. Our team ensures accurate application of modifiers such as -59 to distinguish separate procedures, -51 for multiple procedures, and -26 and -TC to identify professional and technical components. This careful approach minimizes denials and ensures that every component of care is reimbursed appropriately.
ICD-10 Code Selection for GI Conditions
From GERD (K21.9) and Crohn’s disease (K50.90) to colorectal cancer screenings (Z12.11), proper ICD-10 coding is essential for documenting medical necessity and meeting payer guidelines. Our coders stay up to date on evolving coding standards to maintain full compliance and support accurate reimbursement across all payers.
