2027 ICD-10-CM Diagnosis Code M01Direct infections of joint in infectious and parasitic diseases classified elsewhere
M01 is a non-billable ICD-10-CM category code for direct infections of joint in infectious and parasitic diseases classified elsewhere, so it cannot be submitted on claims. Use a more specific code from this category instead, such as M01.X0, M01.X11, M01.X12, and M01.X19.

Specific Coding for Direct infect of joint in infec/parastc dis classd elswhrOverview
Non-specific codes like M01 require more characters. Use one of these billable codes instead:
M01.X for Direct infection of joint in infectious and parasitic diseases classified elsewhere
Use M01.X0 for Direct infection of unspecified joint in infectious and parasitic diseases classified elsewhere
M01.X1 for Direct infection of shoulder joint in infectious and parasitic diseases classified elsewhere
M01.X2 for Direct infection of elbow in infectious and parasitic diseases classified elsewhere
M01.X3 for Direct infection of wrist in infectious and parasitic diseases classified elsewhere
M01.X4 for Direct infection of hand in infectious and parasitic diseases classified elsewhere
M01.X5 for Direct infection of hip in infectious and parasitic diseases classified elsewhere
M01.X6 for Direct infection of knee in infectious and parasitic diseases classified elsewhere
M01.X7 for Direct infection of ankle and foot in infectious and parasitic diseases classified elsewhere
Use M01.X8 for Direct infection of vertebrae in infectious and parasitic diseases classified elsewhere
Use M01.X9 for Direct infection of multiple joints in infectious and parasitic diseases classified elsewhere
Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to M01: its own notes plus those printed at block M00-M25, block M00-M02, and Chapter 13. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- Disorders affecting predominantly peripheral (limb) joints
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- arthropathy in Lyme disease (A69.23)
- gonococcal arthritis (A54.42)
- meningococcal arthritis (A39.83)
- mumps arthritis (B26.85)
- postinfective arthropathy (M02.-)
- postmeningococcal arthritis (A39.84)
- reactive arthritis (M02.3)
- rubella arthritis (B06.82)
- sarcoidosis arthritis (D86.86)
- typhoid fever arthritis (A01.04)
- tuberculosis arthritis (A18.01-A18.02)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Code First
The underlying condition named in the note is sequenced before this code.
Notes
General instructions on how these codes are used.
- This block comprises arthropathies due to microbiological agents. Distinction is made between the following types of etiological relationship:
- a) direct infection of joint, where organisms invade synovial tissue and microbial antigen is present in the joint;
- b) indirect infection, which may be of two types: a reactive arthropathy, where microbial infection of the body is established but neither organisms nor antigens can be identified in the joint, and a postinfective arthropathy, where microbial antigen is present but recovery of an organism is inconstant and evidence of local multiplication is lacking.
- Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition

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:

Questions About M01Overview
Is M01 a billable code?
No. This is a category header that groups the codes for direct infections of joint in infectious and parasitic diseases classified elsewhere, and headers cannot be submitted on claims. Claims for direct infections of joint in infectious and parasitic diseases classified elsewhere need a more specific code from this category, such as M01.X0, M01.X11, and M01.X12.
Can M01 be reported with A69.23?
Not as a rule. The Excludes1 note on M01 lists "arthropathy in Lyme disease (A69.23)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
