ICD Code K80.50

ICD code K80.50 is used to identify the presence of gallstones in the bile duct that do not cause inflammation of the bile duct (cholangitis) or the gallbladder (cholecystitis) and are not causing any blockage. This code is important for healthcare providers to accurately document and bill for the diagnosis of gallstones that are present but not currently causing additional complications or symptoms.

### Diagnostic Criteria for Using ICD Code K80.50

1. Presence of Bile Duct Calculi: Confirmed presence of stones or calculi in the bile duct through imaging studies such as ultrasound, CT scan, or MRI.

2. Absence of Cholangitis: No clinical or laboratory evidence of cholangitis, which includes symptoms such as fever, jaundice, and right upper quadrant pain, along with elevated white blood cell count or liver enzymes.

3. Absence of Cholecystitis: No signs or symptoms of cholecystitis, such as right upper quadrant tenderness, fever, or positive Murphy's sign, and no imaging evidence of gallbladder inflammation.

4. No Obstruction: Imaging studies should show that there is no obstruction in the bile duct, meaning bile flow is not impeded by the presence of calculi.

5. Symptomatology: The patient may present with mild or non-specific symptoms such as abdominal discomfort or nausea, but without the acute symptoms associated with cholangitis or cholecystitis.

6. Laboratory Findings: Liver function tests may be normal or show mild abnormalities, but without the significant elevations typically seen in obstructive jaundice or infection.

7. Exclusion of Other Conditions: Rule out other potential causes of the patient's symptoms and laboratory findings, ensuring that the diagnosis is specific to the presence of bile duct calculi without associated complications.

For the ICD code K80.50, which pertains to calculus of bile duct without cholangitis or cholecystitis without obstruction, the relevant CPT codes that may be applicable include:

1. 47562 - Laparoscopy, surgical; cholecystectomy.

2. 47563 - Laparoscopy, surgical; cholecystectomy with cholangiography.

3. 47564 - Laparoscopy, surgical; cholecystectomy with exploration of common duct.

4. 47600 - Cholecystectomy.

5. 47605 - Cholecystectomy with cholangiography.

6. 47610 - Cholecystectomy with exploration of common duct.

7. 47480 - Choledochotomy; with exploration, ductal dilation, or stone removal.

8. 47570 - Laparoscopy, surgical; with exploration of common duct.

These CPT codes are typically used for procedures related to the treatment of conditions associated with the specified ICD code. It is important for healthcare providers to select the appropriate CPT code based on the specific procedure performed.
