From high-volume screening colonoscopies to complex ERCP interventions and capsule endoscopy, our GI billing specialists navigate the screening-to-diagnostic conversion rules, polyp removal technique coding, and multi-procedure discounting that define gastroenterology reimbursement.
Gastroenterology billing hinges on precise procedure coding, the critical distinction between screening and diagnostic colonoscopies, and technique-specific polyp removal documentation. A single colonoscopy session can generate multiple CPT codes with strict hierarchy rules — and the screening-to-diagnostic conversion impacts both physician and patient cost-sharing obligations.
Colonoscopy codes (45378-45398) are selected based on what happens during the procedure — diagnostic only, biopsy, polyp removal by snare, hot biopsy forceps, or endoscopic mucosal resection. We ensure the highest-reimbursing applicable code is selected based on documented technique and that multiple intervention codes follow proper hierarchy and add-on rules.
When a screening colonoscopy converts to diagnostic (polyp found and removed), billing must reflect the conversion with proper modifier usage (PT modifier for screening-to-therapeutic). This affects patient cost-sharing under ACA preventive care rules. We apply conversion logic correctly to protect both practice revenue and patient financial obligations.
EGD codes (43235-43259) cover diagnostic examination, biopsy, dilation, foreign body removal, hemostasis, and ablation. Each intervention has a distinct code, and multiple interventions during the same EGD follow CCI bundling rules. We capture every billable service while maintaining strict compliance with edit logic.
Endoscopic retrograde cholangiopancreatography (ERCP) is among the most complex GI procedures to code. Multiple interventions — sphincterotomy, stone extraction, stent placement, balloon dilation — may occur in a single session. We ensure each distinct intervention is captured with proper CPT codes and that CCI edits are respected for bundled components.
The reimbursement for polyp removal varies dramatically based on technique — cold forceps biopsy (45380), snare polypectomy (45385), hot biopsy forceps (45384), and endoscopic mucosal resection (45390) each have different CPT codes and payment rates. We ensure documentation captures the specific technique used for each polyp to assign the highest-reimbursing accurate code.
GI procedures performed in ASCs vs. hospital outpatient departments have different facility payment methodologies (ASC payment groups vs. APCs). Many GI practices own or have financial interests in ASCs. We manage both professional and facility billing with proper place-of-service coding and ensure facility claims capture all billable supplies and pathology handling.
Our GI billing team processes thousands of endoscopy claims monthly and understands the revenue dynamics of high-volume procedural practices. We optimize every step from pre-procedure scheduling through pathology result integration and patient balance collection.
Our team codes across the full GI CPT range:
We verify benefits, confirm screening vs. diagnostic indication, obtain prior authorizations when required, check colonoscopy interval eligibility for screening patients, and ensure prep instructions are consistent with the documented indication to prevent claim-documentation mismatches.
Our coders review endoscopy reports within hours of the procedure, assign CPT codes based on documented findings and interventions, select appropriate ICD-10 codes reflecting findings (or screening diagnosis when no pathology is found), and apply modifiers for laterality, screening conversion, and distinct services.
Claims are scrubbed, edited, and submitted electronically on the same day as the procedure for maximum cash flow. We coordinate professional and facility claims for ASC-based procedures and ensure pathology billing aligns with the endoscopist's specimen documentation.
We manage the unique denial patterns in GI billing — screening interval disputes, medical necessity for surveillance colonoscopy, anesthesia denials, and multi-procedure reductions. Patient billing accurately reflects screening cost-sharing protections and clearly communicates any balance due from diagnostic conversions.
Gastroenterology billing involves sensitive procedure data, pathology results, and screening history that must be protected rigorously. Our operations are governed by HIPAA, ISO 27001, and HITRUST security frameworks to ensure your practice and patient data remain secure throughout the revenue cycle.
All endoscopy reports, pathology results, and patient billing data are processed within encrypted, access-controlled systems. Our team operates under strict business associate agreements and undergoes annual compliance training specific to GI practice workflows.
We conduct quarterly coding audits focused on colonoscopy technique documentation, screening-vs-diagnostic accuracy, and multi-procedure compliance. Results identify documentation improvement opportunities and ensure your practice maintains audit-ready coding patterns.
