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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code M02:

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • underlying disease, such as:
  • congenital syphilis Clutton's joints A50.5
  • enteritis due to Yersinia enterocolitica A04.6
  • infective endocarditis I33.0
  • viral hepatitis B15 B19

Type 1 Excludes

Type 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.
  • Behçet's disease M35.2
  • direct infections of joint in infectious and parasitic diseases classified elsewhere M01
  • postmeningococcal arthritis A39.84
  • mumps arthritis B26.85
  • rubella arthritis B06.82
  • syphilis arthritis late A52.77
  • rheumatic fever I00
  • tabetic arthropathy Charcôt's A52.16

Code Classification

  • Diseases of the musculoskeletal system and connective tissue (M00–M99)
    • Infectious arthropathies (M00-M02)
      • Postinfective and reactive arthropathies (M02)

Code History

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016
    (First year ICD-10-CM implemented into the HIPAA code set)
  • FY 2017 - No Change, effective from 10/1/2016 through 9/30/2017
  • FY 2018 - No Change, effective from 10/1/2017 through 9/30/2018

  • FY 2020 - No Change, effective from 10/1/2019 through 9/30/2020

Information for Patients


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.

Infectious 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. Infectious arthritis is an infection in the joint. The infection comes from a bacterial, viral, or fungal infection that spreads from another part of the body. Symptoms of infectious arthritis include

  • Intense pain in the joint
  • Joint redness and swelling
  • Chills and fever
  • Inability to move the area with the infected joint

One type of infectious arthritis is reactive arthritis. The reaction is to an infection somewhere else in your body. The joint is usually the knee, ankle, or toe. Sometimes, reactive arthritis is set off by an infection in the bladder, or in the urethra, which carries urine out of the body. In women, an infection in the vagina can cause the reaction. For both men and women, it can start with bacteria passed on during sex. Another form of reactive arthritis starts with eating food or handling something that has bacteria on it.

To diagnose infectious arthritis, your health care provider may do tests of your blood, urine, and joint fluid. Treatment includes medicines and sometimes surgery.
