What pneumobilia ICD-10 codes can I use?

If you're looking for pneumobilia ICD-10 codes, you'll likely have no results if your search terms are pneumobilia and its other name, aerobilia, because there are no ICD-10-CM codes that mention those in their names. That doesn't mean there aren't any!

You can use the code: K83.8 - Other specified biliary tract diseases. Since there are no ICD-10 codes with pneumobilia in their names, this is the best choice because it's meant to be used for patients with diseases of the biliary tract that don't have specific ICD-10-CM diagnosis codes. This is a billable specific code for this condition.

Is this lone pneumobilia ICD-10 code billable?

Yes. This ICD-10-CM diagnosis code for pneumobilia is valid and billable. When documenting this diagnosis, ensure proper supporting clinical information is included.

Clinical information about pneumobilia

Pneumobilia is the term used by healthcare professionals to describe the condition of having air within the biliary tract. This digestive system includes the gallbladder, liver, pancreas, and bile duct. The condition may also involve the cystic duct in some cases.

Having air in the biliary system isn't necessarily bad, but it can be a sign of gallbladder disease or biliary tract unspecified problems like the following:

  • Dysfunction of the Sphincter of Oddi, which controls the flow of bile and pancreatic juice in the duodenum part of the small intestine;
  • Biliary-enteric fistula, the formation of abnormal passageways between the bile ducts and intestine;
  • The erosion of the gallbladder wall may lead to complications over time.

It can even be caused by a surgical procedure called biliary-enteric anastomosis, which addresses biliary obstruction and leakage. In rare cases, this condition may be associated with biliary tract atrophy or biliary tract hypertrophy.

Pneumobilia may occur after cholecystitis treatment or as part of postcholecystectomy syndrome. Chronic cases might involve cholangitis or calculus of the biliary system. If relevant history exists, patients undergoing anesthesia should be evaluated for this condition.

The official type 1 excludes and type 2 excludes notes for code K83.8 should be reviewed when coding, as they provide important guidance on conditions involving the gallbladder and other aspects of the biliary tract.

Frequently asked questions

What are the symptoms of pneumobilia?

Pneumobilia often presents with mild and vague symptoms such as nausea, diffuse abdominal discomfort, and sometimes vomiting; right upper quadrant pain or tenderness is also common, but many cases may be asymptomatic or have non-specific findings, making clinical diagnosis challenging.

How do healthcare professionals detect/diagnose pneumobilia?

Pneumobilia is primarily diagnosed through imaging studies, with ultrasound revealing highly echogenic foci and reverberation artifacts in the central liver, and CT scans showing linear branching gas in the biliary tree, most prominent in central large ducts; distinguishing pneumobilia from portal venous gas is crucial, as the latter appears more peripherally.

How do healthcare professionals treat pneumobilia?

Treatment of pneumobilia depends on the underlying cause; if it is due to a benign process or is asymptomatic, no intervention may be required, but if associated with infection, fistula, or biliary obstruction, management may include antibiotics, endoscopic or surgical intervention, and addressing any precipitating factors such as trauma, infection, or obstruction.
