K56.50 is a billable diagnosis code used to specify a medical diagnosis of intestinal adhesions [bands], unspecified as to partial versus complete obstruction. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like K56.50 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

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.

Replacement Code

K5650 replaces the following previously assigned ICD-10-CM code(s):

K56.5 - Intestinal adhesions w obst (postprocedural) (postinfection)
K56.5 - Intestinal adhesions with obstruction (postinfection)
