The 6 Biggest Gastroenterology Billing Challenges

Why GI practices lose 12-30% of revenue to these preventable issues

Endoscopy Coding Errors

Misusing CPTs (43235, 43239) or missing modifiers (59, 51) for EGD/colonoscopy bundles leads to 25-40% claim denials. Many practices undercode biopsy charges (88305).
Our GI-Specific Solution:
AAPC-certified GI coders achieve 97% clean claim rate for scopes
*Solution validated by Dr. Alan Weiss, MD, former AGA coding committee

Biologic Drug Billing

Incorrect J-code usage (J1745 infliximab) or missing JW modifiers wastes $18k+/year per GI practice on unreimbursed biologics (Remicade, Stelara).
Our GI-Specific Solution:
Specialized infusion billing recovers 92% of biologic drug costs
*Aligned with 2024 CMS infusion coding guidelines

ASC vs Office Billing

Confusing facility (43235-51) vs professional fee (43235-26) billing causes 35% payment delays for GI groups with ambulatory centers.
Our GI-Specific Solution:
Dual-certified teams streamline 100% compliant ASC billing
*Developed with ASCA compliance experts

Pathology Reconciliation

Unmatched pathology charges (88305 biopsies) result in 22% lost revenue for GI practices doing in-house specimen collection.
Our GI-Specific Solution:
Automated charge capture ensures 100% pathology billing
*System integrates with ProPath, Caris labs

Prior Auth Delays

Slow approvals for capsule endoscopy (91110) and complex scopes cause 45+ day revenue cycles.
Our GI-Specific Solution:
Dedicated auth team secures approvals in 72hr avg
*98% success rate for UnitedHealthcare GI auths

MIPS Penalties

Failing GI-specific measures (G2211, G2067) risks 9% Medicare payment cuts.
Our GI-Specific Solution:
Custom MIPS tracking achieves 95+ percentile scores
*Certified by NAHQ for GI quality reporting

Wonderful customer service and quick Credentialing!
Rx Credentialing LLC did an excellent job helping my practice join the MCOs. Their team made the process seamless and stress-free, answering all my questions promptly. I highly recommend them—their service is efficient, professional, and reasonably priced! 😁
I am a licensed psychotherapist and could not be more pleased with the efficient, professional services from RX credentialing services. No AI or bots here. Instead, RX offers real human beings who understand the needs of solo providers or group practice owners who are spread thin and have to wear many hats. Rx has hired talented individuals, like my account manager, Tyler, who will go the extra mile for you to ensure credentialing goes smoothly. We hit a hiccup on the road to becoming credentialed, but Tyler quickly intervened, advocating for my business so that the issue was resolved and I was approved for various insurance panels--some which have very high bars or administrative requirements. RX handled it all, informing me through each step of the process with clear and concise credentialing updates that put my fears to rest. Their services are kind of like therapy for therapists, because when you worry less about admin burdens, you can better focus on the client, while growing your business capacity. I would highly recommend them to any solo or group practice needing such services.

RxCredentialing has been a wonderful partner in helping with my credentialing for my new primary care practice as well as are assisting me with a few other services. They are very knowledgeable and most importantly they are not pushy in working with my needed timeline. Moreover, they are very responsive, and I am looking forward to expanding our relationship to include their other services such as medical billing. I was fortunate to find them while searching the web and so refreshing to deal with an organization that is really focused on helping me establish a medical practice the smart way and not just spend money foolishly on things I do not need until the time is right.

Tyler has been an excellent person to work with. He kept us (our clinic) informed of our status throughout the credentialling process. They did the "heavy lifting" tracking down and following up so we didn't need to. Because this company handled our credentialling process, it allowed our company to focus on our number one priority--patient care. Thanks for taking care of us!!

Trusting a third party with your sensitive information can be difficult. I encountered this challenge while seeking credentialing services for my business with various insurance providers. Although I received numerous proposals from credentialing firms, I was uncertain about the security of my personal data. A trusted colleague recommended Rx Credentialing LLC, based on her positive experience. I decided to engage their services, and I’m pleased to report that they handled my information securely. Moreover, their expertise and competitive pricing make them an excellent choice for anyone needing credentialing support.
