M81.8 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.

Convert M81.8 to ICD-9-CM

• ICD-9-CM Code: 733.02 - Idiopathic osteoporosis
  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: 733.03 - Disuse osteoporosis
  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: 733.09 - Osteoporosis NEC
  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

Osteoporosis

Osteoporosis is a disease that thins and weakens the bones. Your bones become fragile and fracture (break) easily, especially the bones in the hip, spine, and wrist. In the United States, millions of people either already have osteoporosis or are at high risk due to low bone mass.

Anyone can develop osteoporosis, but it is more common in older women. Risk factors include:

• Getting older
• Being small and thin
• Having a family history of osteoporosis
• Taking certain medicines
• Being a white or Asian woman
• Having low bone density

Osteoporosis is a silent disease. You might not know you have it until you break a bone. A bone mineral density test is the best way to check your bone health.

To keep bones strong, eat a diet rich in calcium and vitamin D, exercise, and do not smoke. If needed, medicines can also help. It is also important to try to avoid falling down. Falls are the number one cause of fractures in older adults.
