Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Infectious arthropathies
      (M00-M02)
      • Direct infections of joint in infectious and parasitic diseases classified elsewhere
        (M01)

M01 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of direct infections of joint in infectious and parasitic diseases classified elsewhere. The code is not specific and is NOT valid for the year 2024 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.

Specific Coding Applicable to Direct infect of joint in infec/parastc dis classd elswhr

Non-specific codes like M01 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for direct infect of joint in infec/parastc dis classd elswhr:

  • M01.X for Direct infection of joint in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • Use M01.X0 for Direct infection of unspecified joint in infectious and parasitic diseases classified elsewhere - BILLABLE CODE

  • M01.X1 for Direct infection of shoulder joint in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X2 for Direct infection of elbow in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X3 for Direct infection of wrist in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X4 for Direct infection of hand in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X5 for Direct infection of hip in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X6 for Direct infection of knee in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • M01.X7 for Direct infection of ankle and foot in infectious and parasitic diseases classified elsewhere - NON-BILLABLE CODE

  • Use M01.X8 for Direct infection of vertebrae in infectious and parasitic diseases classified elsewhere - BILLABLE CODE

  • Use M01.X9 for Direct infection of multiple joints in infectious and parasitic diseases classified elsewhere - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


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:
  • leprosy Hansen's disease A30
  • mycoses B35 B49
  • O'nyong-nyong fever A92.1
  • paratyphoid fever A01.1 A01.4

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.

Patient Education


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.
