M13.8 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of other specified arthritis. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
- 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.
- 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.
Specific Coding for Other specified arthritis
Non-specific codes like M13.8 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other specified arthritis:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Allergic arthritis
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:
If you feel pain and stiffness in your body or have trouble moving around, you might have arthritis. Most kinds of arthritis cause pain and swelling in your joints. Joints are places where two bones meet, such as your elbow or knee. Over time, a swollen joint can become severely damaged. Some kinds of arthritis can also cause problems in your organs, such as your eyes or skin.
Types of arthritis include:
- Osteoarthritis is the most common type of arthritis. It's often related to aging or to an injury.
- Autoimmune arthritis happens when your body's immune system attacks healthy cells in your body by mistake. Rheumatoid arthritis is the most common form of this kind of arthritis.
- Juvenile arthritis is a type of arthritis that happens in children.
- Infectious arthritis is an infection that has spread from another part of the body to the joint.
- Psoriatic arthritis affects people with psoriasis.
- Gout is a painful type of arthritis that happens when too much uric acid builds up in the body. It often starts in the big toe.
