K56.49 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
388	GASTROINTESTINAL OBSTRUCTION WITH MCC	06	1.4535
389	GASTROINTESTINAL OBSTRUCTION WITH CC	06	0.7964
390	GASTROINTESTINAL OBSTRUCTION WITHOUT CC/MCC	06	0.559

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.

Convert K56.49 to ICD-9-CM

• ICD-9-CM Code: 560.30 - Impaction intestine NOS
  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.
• ICD-9-CM Code: 560.39 - Impaction intestine NEC

Patient Education

Intestinal Obstruction

An intestinal obstruction occurs when food or stool cannot move through the intestines. The obstruction can be complete or partial. There are many causes. The most common are adhesions, hernias, cancers, and certain medicines.

Symptoms include:

• Severe abdominal pain or cramping
• Vomiting
• Bloating
• Loud bowel sounds
• Swelling of the abdomen
• Inability to pass gas
• Constipation

A complete intestinal obstruction is a medical emergency. It often requires surgery.
