Clinical Information

• Arthritis

  acute or chronic inflammation of joints.

• Arthritis, Experimental

  arthritis that is induced in experimental animals. immunological methods and infectious agents can be used to develop experimental arthritis models. these methods include injections of stimulators of the immune response, such as an adjuvant (adjuvants, immunologic) or collagen.

• Arthritis, Gouty

  arthritis, especially of the great toe, as a result of gout. acute gouty arthritis often is precipitated by trauma, infection, surgery, etc. the initial attacks are usually monoarticular but later attacks are often polyarticular. acute and chronic gouty arthritis are associated with accumulation of monosodium urate in and around affected joints.

• Arthritis, Infectious

  arthritis caused by bacteria; rickettsia; mycoplasma; viruses; fungi; or parasites.

• Arthritis, Juvenile

  arthritis in children, with onset before 16 years of age. the terms juvenile rheumatoid arthritis (jra) and juvenile idiopathic arthritis (jia) refer to classification systems for chronic arthritis in children. only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

• Arthritis, Psoriatic

  a type of inflammatory arthritis associated with psoriasis, often involving the axial joints and the peripheral terminal interphalangeal joints. it is characterized by the presence of hla-b27-associated spondylarthropathy, and the absence of rheumatoid factor.

• Arthritis, Reactive

  an aseptic, inflammatory arthritis developing secondary to a primary extra-articular infection, most typically of the gastrointestinal tract or urogenital system. the initiating trigger pathogens are usually shigella; salmonella; yersinia; campylobacter; or chlamydia trachomatis. reactive arthritis is strongly associated with hla-b27 antigen.

• Arthritis, Rheumatoid

  a chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. etiology is unknown, but autoimmune mechanisms have been implicated.

• Arthritis-Encephalitis Virus, Caprine

  a species of lentivirus, subgenus ovine-caprine lentiviruses (lentiviruses, ovine-caprine), closely related to visna-maedi virus and causing acute encephalomyelitis; chronic arthritis; pneumonia; mastitis; and glomerulonephritis in goats. it is transmitted mainly in the colostrum and milk.

• Crystal Arthropathies

  joint disorders that are characterized by accumulation of microcrystals in and around the joint including in the synovial fluid. they are classified according to the chemical nature of the crystals such as calcium pyrophosphate; basic calcium phosphates; and monosodium urate (see uric acid).

• Lyme Disease

  an infectious disease caused by a spirochete, borrelia burgdorferi, which is transmitted chiefly by ixodes dammini (see ixodes) and pacificus ticks in the united states and ixodes ricinis (see ixodes) in europe. it is a disease with early and late cutaneous manifestations plus involvement of the nervous system, heart, eye, and joints in variable combinations. the disease was formerly known as lyme arthritis and first discovered at old lyme, connecticut.

• Osteoarthritis

  a progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. the disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. in the foreign literature it is often called osteoarthrosis deformans.

• Rheumatic Fever

  a febrile disease occurring as a delayed sequela of infections with streptococcus pyogenes. it is characterized by multiple focal inflammatory lesions of the connective tissue structures, such as the heart, blood vessels, and joints (polyarthritis) and brain, and by the presence of aschoff bodies in the myocardium and skin.

• Spondylarthritis

  inflammation of the joints of the spine, the intervertebral articulations.

• Osteoarthritis, Hip

  noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. it is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. a dominant symptom is pain on weight-bearing or motion.

• Osteoarthritis, Knee

  noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (crenshaw, campbell's operative orthopaedics, 8th ed, p2019)

• Osteoarthritis, Spine

  a degenerative joint disease involving the spine. it is characterized by progressive deterioration of the spinal articular cartilage (cartilage, articular), usually with hardening of the subchondral bone and outgrowth of bone spurs (osteophyte).

• Joints

  also known as articulations, these are points of connection between the ends of certain separate bones, or where the borders of other bones are juxtaposed.

• Spine

  the spinal or vertebral column.

M19.90 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.

Osteoarthritis

What is osteoarthritis?

Osteoarthritis, sometimes called OA, is a type of arthritis that only affects the joints, usually in the hands, knees, hips, neck, and lower back. It's the most common type of arthritis.

In a healthy joint, the ends of the bones are covered with a smooth, slippery tissue called cartilage. The cartilage pads the bones and helps them glide easily when you move the joint. With osteoarthritis, the cartilage breaks down and becomes rough. Sometimes, all the cartilage wears away and the bones rub together. Bumps of extra bone called bone spurs may grow in the joint area.

There is no cure for osteoarthritis. It usually gets worse slowly. But there's a lot you can do to manage the symptoms.

What are the symptoms of osteoarthritis?

Osteoarthritis affects people in different ways, and not everyone has pain. The most common symptoms are:

• Pain when you move, which often gets better with rest
• Stiffness, especially for the first 30 minutes after you get up from resting
• Swollen joints, especially after using the joint a lot
• Less movement in the joint than normal
• A joint that feels loose or unstable

What causes osteoarthritis?

Researchers aren't sure what causes osteoarthritis. They think that it could be caused by a combination of factors in the body and the environment. Your chance of developing osteoarthritis increases with age. They also know that some people are more likely to develop it than others.

Who is more likely to develop osteoarthritis?

Things that make you more likely to develop osteoarthritis include:

• Aging. Osteoarthritis can happen at any age, but the chance of getting it increases in middle-aged adults and older. After age 50, it is more common in women than in men.
• Being overweight. Extra weight puts more stress on your joints.
• Having a past injury or surgery on a joint. This is often the cause of osteoarthritis in younger adults.
• Doing a lot of activities that overuse the joint. This includes sports with a lot of jumping, twisting, running, or throwing.
• Having a joint that doesn't line up correctly.
• A family history of osteoarthritis. Some people inherit genetic changes that increase their chance of developing osteoarthritis.

How is osteoarthritis diagnosed?

There is no specific test for osteoarthritis. To find out if you have osteoarthritis, your provider:

• Will ask about your symptoms and medical history
• Will do a physical exam
• May use x-rays or other imaging tests to look at your joints
• May order lab tests to make sure that a different problem isn't causing your symptoms

What are the treatments for osteoarthritis?

The goal of treating osteoarthritis is to ease your pain, help you move better, and stop it from getting worse.

Treatment usually begins with:

• Exercises to improve strength, flexibility and balance
• Weight loss, if needed, to improve pain, especially in your hips or knees
• Braces or shoe inserts (orthotics) that a health care provider fits for you

You can buy some pain relievers and arthritis creams without a prescription. They can be helpful, but it's best to talk to your provider about using them. If they don't help enough, your provider may prescribe injections (shots) into the joint or prescription pain relievers.

Complementary therapies may help some people. Massage can increase blood flow and bring warmth to the area. Some research shows that acupuncture may help relieve osteoarthritis pain. Simple things like heat and ice can help, too.

If none of these treatments help enough, surgery may be an option. You and your provider can decide if it's right for you.
