Gastroenterology Medical Coding

Gastroenterology Medical Coding

Are you aware of the changes introduced to the lower endoscopy codes and the major revision to enteroscopy? You need to know how to code for new and emergent GI technologies if you are to receive the right reimbursement. Gastroenterology medical coding poses several challenges – there are significant differences between colonoscopy screening and diagnostic colonoscopy, and you may have a tough time reporting multiple endoscopy procedures.

Gastroenterologists can consider outsourcing their coding tasks to Outsource Strategies International (OSI). Our HIPAA-compliant medical coding company serves clinics, doctors, physicians, medical groups, billing companies, and many independent and organization-linked gastroenterologists across the U.S.

Benefit from 30% to 40% cost savings with OSI as your service provider.

Call (800) 670-2809 to discuss your requirements with our solutions manager.

Gastroenterology Coding by Expert Medical Coders

Our AAPC-certified coders have thorough knowledge in the latest CPT, ICD-9, ICD-10, and HCPCS codes. We follow AMA and CMS guidelines at every step.

Here’s how they can support you.

  • Assign proper codes for surgical procedures performed by gastroenterologists such as colonoscopies, esophageal dilations, and ERCP among others
  • They can efficiently handle challenges such as coding for colorectal cancer screenings vs. colonoscopies, documenting the appropriate levels of E/M services, using category III codes for the treatment of GERD (Gastro esophageal Reflux Disease), and appending the right modifiers -51, -59 and -26
  • Assign proper diagnosis codes for Barrett’s esophagus, Crohn’s disease and other gastrointestinal disorders
  • Assign payer-specific codes
  • Choose appropriate initial observation care time component codes, prolonged services codes and modifiers
  • Emergency room e-code evaluation
  • Validation of DRG and ICD-9 codes

An Exceptional Medical Billing Company I am an orthopedic surgeon and was looking forward to outsourcing the billing task to a trusted orthopedic medical billing company. I chose OSI taking into account its good track record. I would rate it as an exceptional medical billing company. The staff is knowledgeable, well-mannered, and has always been prompt in addressing my concerns. My practice revenue has improved considerably since my tie-up with this company. I would gladly recommend OSI to anyone looking to outsource medical billing. Andrew Paul

The Best Business Decision I Ever Made!!! I was really frustrated trying to balance patient care and medical billing responsibility. One of my friends who had a good experience with OSI suggested medical billing outsourcing which was not even in my thoughts. I entrusted the medical billing job to OSI and it is the best business decision I have ever made in my career. Joshua Samuel
