ICD-10 code gallstone refers to the specific classification used in the International Classification of Diseases, Tenth Revision (ICD-10), to identify and document cases of gallstones, also known as cholelithiasis. Accurate coding is essential for clinical documentation, insurance reimbursement, epidemiological research, and public health surveillance. This article explores the details surrounding the ICD-10 code for gallstones, including its classification, clinical implications, and coding guidelines.

What Are Gallstones?
Before delving into the coding specifics, it’s important to understand what gallstones are.
Definition and Types of Gallstones
Gallstones are solid particles that form within the gallbladder, a small organ located beneath the liver responsible for storing and concentrating bile. Bile is a digestive fluid that helps break down fats. When the components of bile, such as cholesterol or bilirubin, become imbalanced, they can precipitate and form stones.
The main types of gallstones include:
- Cholesterol Gallstones: The most common type, primarily composed of cholesterol.
- Pigment Gallstones: Made of bilirubin, usually darker and associated with hemolytic diseases.
- Mixed Gallstones: Contain a mixture of cholesterol and pigment.
Symptoms and Complications
While some gallstones are asymptomatic, others can cause:
- Biliary colic (pain in the upper right abdomen)
- Nausea and vomiting
- Jaundice if the bile duct is obstructed
- Cholecystitis (inflammation of the gallbladder)
- Pancreatitis if the pancreatic duct is blocked

ICD-10 Coding for Gallstone Conditions
The Significance of Accurate Coding
The ICD-10 coding system assigns specific codes to various diagnoses, enabling consistent documentation across healthcare settings. The code for gallstones is critical for:
- Medical record keeping
- Reimbursement claims
- Disease prevalence analysis
- Research and public health initiatives
Primary ICD-10 Code for Gallstones
The main ICD-10 code for gallstones is:
- K80. — Calculus of gallbladder
This code encompasses various types of gallstones and related conditions.
---
Detailed Breakdown of the ICD-10 Code K80
K80.1 – Calculus of gallbladder with cholecystitis
Indicates the presence of gallstones along with inflammation of the gallbladder.
K80.2 – Calculus of gallbladder with other complications
Used when gallstones are associated with complications such as obstruction or infection but without cholecystitis.
K80.3 – Calculus of gallbladder with acute cholecystitis
Refers to acute inflammation in the gallbladder caused by gallstones.
K80.4 – Calculus of gallbladder with gangrenous cholecystitis
Indicates severe, gangrenous inflammation due to gallstones.
K80.5 – Calculus of gallbladder with perforation
Used when gallstones lead to perforation of the gallbladder wall.
K80.8 – Other specified diseases of gallbladder with calculi
For gallbladder conditions related to stones that do not fit into other categories.
K80.9 – Disease of gallbladder with calculus, unspecified
When the specifics of the gallstone condition are not documented.
---
Coding for Other Gallstone-Related Conditions
K80.0 – Calculus of gallbladder without cholecystitis
Indicates gallstones present without inflammation.
K80.6 – Calculus of bile duct with cholangitis
When stones obstruct the common bile duct causing infection.
K80.7 – Calculus of bile duct without cholangitis
Bile duct stones without associated infection.
K80.9 – Disease of gallbladder with calculus, unspecified
Used when the exact nature of the gallstone condition is not clarified.

Clinical Implications of Coding
Accurate ICD-10 coding for gallstones influences various aspects of healthcare:
- Treatment planning: Correctly identifying the type and severity guides management decisions, such as surgical removal or medical therapy.
- Insurance coverage: Precise codes ensure appropriate reimbursement.
- Epidemiology: Data derived from coding helps track the prevalence and incidence of gallstone disease.
- Research: Enables population studies and evaluation of treatment outcomes.

Coding Guidelines and Best Practices
When to Use Specific Codes
- Use the most specific code available based on documented clinical findings.
- If the type of gallstone is not specified, use the unspecified code (K80.9).
- For gallstones with complications, select the code that best describes the complication (e.g., K80.1 for gallstones with cholecystitis).
Additional Coding Considerations
- Sequela codes: If a patient has residual effects from prior gallstone disease, consider using applicable sequela codes.
- Comorbid conditions: Document other conditions such as cholangitis or pancreatitis separately as needed.
- Laterality: Gallstones are generally not laterality-specific; however, specify if the documentation indicates a specific gallbladder or duct involved.

Summary
The ICD-10 code for gallstone disease primarily falls under K80 and its subcategories, providing a structured way to classify various presentations and complications of gallstones. Accurate coding is vital for clinical management, reimbursement, and public health data collection.
Key Takeaways:
- The main code for gallstones is K80.
- Subcategories specify whether the condition involves inflammation, complications, or is unspecified.
- Proper coding depends on detailed clinical documentation.
- Knowledge of ICD-10 codes enhances communication among healthcare providers and supports effective healthcare delivery.

Final Thoughts
Understanding the ICD-10 code for gallstone disease is essential for healthcare professionals, coders, and administrators alike. Precise coding ensures patients receive appropriate care, facilitates research and epidemiological tracking, and maintains compliance with health regulations. As medical knowledge and coding standards evolve, staying current with guidelines is necessary to accurately document gallstone-related conditions.
