M93.073 is a billable diagnosis code used to specify a medical diagnosis of acute on chronic slipped upper femoral epiphysis, unspecified stability (nontraumatic), unspecified hip. 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 M93.073 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.

Clinical Classification

Clinical Category is Other specified bone disease and musculoskeletal deformities
CCSR Category Code: MUS028
Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

M93.073 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
553	BONE DISEASES AND ARTHROPATHIES WITH MCC	08	1.3515
554	BONE DISEASES AND ARTHROPATHIES WITHOUT MCC	08	0.8218

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.
