2024 ICD-10-CM Diagnosis Code M93.90

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Apophysitis
• Epiphysitis
• Osteochondritis
• Osteochondropathy

Clinical Information

• Legg-Calve-Perthes Disease

  a particular type of femur head necrosis occurring in children, mainly male, with a course of four years or so.

• Osteochondritis

  inflammation of a bone and its overlaying cartilage.

• Osteochondritis Dissecans

  a type of osteochondritis in which articular cartilage and associated bone becomes partially or totally detached to form joint loose bodies. affects mainly the knee, ankle, and elbow joints.

• Femur Head Necrosis

  aseptic or avascular necrosis of the femoral head. the major types are idiopathic (primary), as a complication of fractures or dislocations, and legg-calve-perthes disease.

• Cartilage

  a non-vascular form of connective tissue composed of chondrocytes embedded in a matrix that includes chondroitin sulfate and various types of fibrillar collagen. there are three major types: hyaline cartilage; fibrocartilage; and elastic cartilage.

• Apophysitis

  inflammation of a bony outgrowth located near the attachment site for muscles.

• Osteochondritis

  inflammation of the bone and cartilage.

• Osteochondritis Dissecans

  osteochondritis that is characterized by fragmentation of cartilage and bone.

M93.90 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 M93.90 to ICD-9-CM

• ICD-9-CM Code: 732.9 - Osteochondropathy 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.

Patient Education

Bone Diseases

Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium, vitamin D, and exercise. You should also avoid smoking and drinking too much alcohol.

Bone diseases can make bones easy to break. Different kinds of bone problems include:

• Low bone density and osteoporosis, which make your bones weak and more likely to break
• Osteogenesis imperfecta makes your bones brittle
• Paget's disease of bone makes them weak
• Bones can also develop cancer and infections
• Other bone diseases, which are caused by poor nutrition, genetics, or problems with the rate of bone growth or rebuilding

Cartilage Disorders

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.

Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include :

• Tears and injuries, such as sports injuries
• Genetic factors
• Other disorders, such as some types of arthritis

Osteoarthritis results from breakdown of cartilage.
