Esophageal function testing: Billing and coding update

Area of Science:

• Gastroenterology
• Medical Coding
• Health Economics

Background:

• Esophageal function testing is crucial for diagnosing and managing esophageal disorders.
• Technological advancements have improved diagnostic accuracy but outpaced coding and reimbursement education.
• A lack of clear guidelines exists for Common Procedural Terminology (CPT) codes related to these tests.

Purpose of the Study:

• To summarize CPT codes for esophageal function testing.
• To analyze reimbursement trends associated with these codes.
• To provide practical coding recommendations and advocate for code review by professional societies.

Main Methods:

• Review of current Common Procedural Terminology (CPT) codes for esophageal function testing.
• Analysis of historical and current reimbursement data.
• Synthesis of practical coding strategies and identification of discrepancies.

Main Results:

• Identification of specific CPT codes applicable to various esophageal function tests.
• Demonstration of trends in reimbursement, noting potential inadequacies.
• Evidence of discrepancies in coding definitions and reimbursement levels.

Conclusions:

• Accurate coding and adequate reimbursement are essential for the continued use of advanced esophageal function testing.
• Standardized coding practices and updated reimbursement policies are needed.
• Professional societies should review and potentially revise current CPT codes and reimbursement structures.
