We all know that gastrointestinal endoscopy is one of the most common and vital procedures that you often perform in your GI practice. It helps you diagnose issues like acid reflux and cure conditions like ulcers in your patients. These procedures often come under your daily routine, but what makes your life troublesome is the billing for these specific GI procedures. Now, things have even become further complex with new changes. CMS has come up with the latest billing guidelines outlining the coding rules for both diagnostic and therapeutic upper GI endoscopies. The truth is that many gastroenterology practices may get overwhelmed with these detailed coding guidelines, and this is where professional gastroenterology billing services can make things convenient as they ensure that everything is done right the first time.

Now, you might be wondering to know about the key changes regarding how upper GI endoscopy services should be billed, right? Here are some key highlights from CMS that you need to know.

Know what's new coding updates in gastroenterology billing services

The updated article now follows LCD L35350, which lists the conditions that justify doing an upper GI endoscopy. You must use the right ICD-10-CM codes to prove the procedure was medically necessary. CMS also wants clear, readable documentation that connects the diagnosis to the service. If the service isn't fully covered, you need to add the correct modifiers to show the patient was informed and agreed to go ahead. There's also a long list of approved diagnosis codes, including cancer, benign tumors, inflammation, bleeding, and more. All of this makes accurate coding more important than ever. One small mistake can lead to denials, delays, or even audits. Fortunately, working with a professional gastroenterology billing service can be your ideal resort.

Gastroenterology billing services for gastrointestinal endoscopy may sound simple but the reality is that there are multiple complex components. Let's know about some of the common hurdles that GI practices often encounter.

ICD-10-CM Coding Must Match the LCD

You need to select diagnosis codes that align with LCD L35350. If the ICD-10 code you use doesn't match what's listed, your claim could be denied—even if the procedure was medically necessary.

Modifiers Matter

Using the wrong modifier—or forgetting to add one—can cause your reimbursement to be delayed or denied. These modifiers explain whether a procedure was elective, not fully covered, or part of a larger set of services.

Documentation Must Be Precise

You can't just list the CPT code. You also need supporting documentation that clearly shows why the service was needed and what was done. The records must be legible and must include patient identifiers.

Handling your billing in-house may seem like the easier option but it is not in reality.

The risks of errors are higher with new CMS updates. However, a professional gastroenterology billing service can actually bring the real value on the table in the following ways.

How Gastroenterology Billing Services Can Help

Gastroenterology billing services know the latest CMS rules, payer updates, and medical necessity guidelines. They use the correct ICD-10 and CPT codes every time. They also help reduce denials by spotting coding mistakes, missing documents, or mismatched info before claims go out. If your procedure needs modifiers, they make sure the right ones are added to avoid delays. They also keep up with different insurance policies, so your claims meet each payer's rules. Most importantly, they save you time by handling all the billing work—so you can focus on your patients, not paperwork.

Choosing the Right Gastroenterology Billing Service

Make sure their system is HIPAA-compliant to keep patient data safe. It also helps if they handle prior authorizations, eligibility checks, and denial management—these services are a key part of getting your billing right.
