Hepatology billing covers three groups of liver care claims: FibroScan tests, hepatitis care and the procedures a liver clinic performs.
FibroScan is billed with CPT 91200 and needs a covered liver diagnosis and respect for payer frequency limits. Hepatitis care is billed through specific diagnosis codes, visits leveled on decision making and early prior authorization for antiviral drugs.
Liver clinic claims, such as biopsy, paracentesis and variceal banding, each need their own codes and same-day checks. Most liver clinics run inside a GI group, so these rules are easy to overlook. This guide explains each one.
How Hepatology Billing Differs From GI Billing
GI billing is built around procedures. A colonoscopy or EGD is scheduled, performed and billed as one event. Hepatology is built around long-term care. A patient with hepatitis B, cirrhosis or MASH may be seen for years, with repeat FibroScans, lab monitoring and specialty drugs.
So hepatology billing and coding needs a different rhythm. The team tracks frequency limits, renewal dates and fibrosis results, not just same-day edits.
Results should also be measured separately. Our gastroenterology RCM KPIs post shows which numbers to watch.
FibroScan and Elastography Claims
FibroScan is often the most-billed test in a liver clinic, and one of the most denied. These five points decide whether it gets paid.
Choose 91200 or 76981 Correctly
A standard FibroScan is transient elastography without imaging, billed with CPT 91200.
CPT 76981 is for ultrasound elastography of liver tissue, with imaging and saved images documented. Using 76981 for a standard FibroScan is a common error.
Link a Covered Diagnosis
Payers usually cover FibroScan for chronic hepatitis B or C, alcohol-related liver disease, MASLD or MASH and hemochromatosis.
One commercial payer policy lists these conditions and requires the diagnosis on the claim.
Respect Frequency Limits
Many payers allow elastography only once or twice a year. A sooner repeat needs a documented clinical reason, or it will deny.
Check Biopsy Timing
Some policies do not cover elastography within six months of a liver biopsy. Check biopsy history before scheduling.
Save FIB-4 and Results
Payers increasingly expect an inconclusive or high FIB-4 score before a FibroScan.
Saving that score, the stiffness result and the interpretation also supports drug approvals later.
Coding Hepatitis Care Visits
Hepatitis and chronic liver disease visits are the backbone of liver clinic billing. Four habits decide how they are paid.
Diagnosis specificity comes first. Use chronic hepatitis C (B18.2) or chronic hepatitis B (B18.1) when documented, not unspecified codes. MASH (K75.81) and alcoholic cirrhosis (K70.30, or K70.31 with ascites) need the same care.
Our gastroenterology ICD-10 codes guide covers the wider GI code set. Liver cancer is covered in our HCC medical coding post.
Visit levels follow decision making. Managing cirrhosis, reviewing labs and adjusting antivirals often supports a moderate or high level. Many hepatitis visits are undercoded at a middle level.
G2211 rewards ongoing care. Medicare pays this add-on when the provider is the continuing focal point for a serious condition such as chronic hepatitis. It is generally not paid with modifier 25 for a same-day procedure.
Monthly care can be billed too. Patients with two or more chronic conditions may qualify for chronic care management (99490, 99491), with consent and tracked time.
Screening is billed on its own. Medicare covers hepatitis C screening for eligible patients under G0472.
Antiviral and MASH Drug Approvals
Hepatitis care often depends on costly drugs that need payer approval first. These five steps decide how fast patients start treatment.
Hepatitis C Antivirals
Payers usually ask for a confirmed HCV RNA result and fibrosis staging.
Requests should match AASLD-IDSA HCV guidance, which most payers follow.
Hepatitis B Antivirals
Many hepatitis B drugs are generic, but some plans still require approval for brand products. Include viral load and liver enzymes.
MASH Therapies
Newer MASH drugs such as resmetirom are approved for noncirrhotic MASH with moderate to advanced fibrosis.
Payers often want FibroScan or biopsy results showing that stage, which is why saved results matter.
Specialty Pharmacy Follow-Up
Most liver drugs ship from a specialty pharmacy. Confirm the approval reached the pharmacy and copay help is in place.
Renewals and Re-Approvals
Long-term therapies often need re-approval every 6 to 12 months. Tracking expiry dates prevents treatment gaps.
Our post on speeding up prior authorization shows how to shorten approval times.
Liver Clinic Claims Inside a GI Group
When the liver clinic shares a billing team with endoscopy, its procedures are often coded with GI habits.
The table lists the liver clinic claims GI groups bill most and what to check before each one goes out.
| Liver clinic claim | Common codes | What to check |
|---|---|---|
| Liver biopsy | 47000, plus 76942 for ultrasound guidance | Guidance documented with saved images; note the date, since some payers deny elastography within six months |
| Paracentesis | 49082 without imaging, 49083 with imaging | Imaging guidance is included in 49083, so it is not billed separately |
| Variceal banding | 43244 | Cirrhosis and varices diagnoses linked; no extra diagnostic EGD code |
| FibroScan with a visit | 91200 plus an E/M with modifier 25 | Visit is separately documented, beyond the test review |
| Hepatitis C screening | G0472 | Patient meets Medicare eligibility and frequency rules |
Same-day claims need the most care. A biopsy on a clinic day, or banding during a planned EGD, can trigger bundling edits.
Set modifiers and link diagnoses before submission, not after the denial. That one step protects most liver clinic billing revenue.
Questions for a Hepatology Billing Team
Not every GI billing team has worked liver clinic claims. Before handing over hepatology billing, ask a few direct questions.
Start with FibroScan. The team should explain when it uses 91200 versus 76981 and how it tracks frequency limits.
Next, ask about hepatitis care. Do they audit diagnosis specificity, apply G2211 and chronic care management, and manage antiviral approvals and renewals?
Finally, ask for hepatology results reported separately from GI. In one GI engagement, MBW RCM reduced A/R by 42 days with this kind of tracking.

One Team for GI and Hepatology Claims
Hepatology billing works best as its own service line, even inside a GI group. FibroScan claims need the right code, a covered diagnosis and frequency checks. Hepatitis care needs specific diagnoses, full credit for complex visits and drug approvals filed early. Liver clinic claims need procedure codes and same-day edits checked before submission.
Payers build their rules on AASLD practice guidelines, so billing should follow the same evidence.
For GI groups that want one team for both, MBW RCM provides hepatology billing services within its gastroenterology billing and coding work, covering endoscopy and liver clinic claims together.
