K80.51 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
444	DISORDERS OF THE BILIARY TRACT WITH MCC	07	1.6332
445	DISORDERS OF THE BILIARY TRACT WITH CC	07	1.0868
446	DISORDERS OF THE BILIARY TRACT WITHOUT CC/MCC	07	0.8015

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Gallstones

Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.

Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the bile ducts. That is usually a gallstone. Gallstones form when substances in bile harden. Gallstone attacks usually happen after you eat. Signs of a gallstone attack may include nausea, vomiting, or pain in the abdomen, back, or just under the right arm.

Gallstones are most common among older adults, women, overweight people, Native Americans and Mexican Americans.

Gallstones are often found during imaging tests for other health conditions. If you do not have symptoms, you usually do not need treatment. The most common treatment is removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways to reach your small intestine.
