M01 refers to Direct infections of joint in infectious and parasitic diseases classified elsewhere, a category of joint infections or post-infectious inflammatory joint disorders. These conditions can result from bacterial, viral, or parasitic infections either directly invading the joint or triggering immune-mediated inflammation after infection elsewhere.

Symptoms

Joint swelling and pain – Common in pyogenic arthritis (M00)
Warmth and redness over joints – Seen in active joint infections (M00, M01)
Fever and systemic symptoms – Particularly with direct infections (M01)
Joint stiffness – Often follows postinfective or reactive arthropathies (M02)
Reduced range of motion – Indicative of severe inflammation or joint damage

Diagnosis

Diagnosis of Direct infections of joint in infectious and parasitic diseases classified elsewhere involves joint aspiration and fluid analysis, blood cultures, inflammatory markers (CRP, ESR), imaging (X-rays, MRI), and detailed infection history. Rapid diagnosis is critical to prevent permanent joint damage.

ICD10 Code Usage

ICD10 code M01 is used by rheumatologists, orthopedic surgeons, infectious disease specialists, and emergency medicine doctors for documenting infectious or reactive arthritis, supporting antibiotic therapy, surgical interventions, and rehabilitation.

FAQs

Q1: What is ICD10 code M01?
A: It refers to Direct infections of joint in infectious and parasitic diseases classified elsewhere, involving infection or post-infection inflammation of joints, leading to pain, swelling, and limited mobility.

Q2: What distinguishes M00 from M01?
A: M00 is primary pyogenic arthritis (direct infection by bacteria), while M01 covers joint infections secondary to systemic infectious diseases like tuberculosis or syphilis.

Q3: What are reactive arthropathies (M02)?
A: Joint inflammation triggered by infections elsewhere in the body (e.g., post-gastrointestinal or urogenital infections), without direct joint infection.

Q4: How are these conditions treated?
A: Treatment may involve intravenous antibiotics, drainage procedures, anti-inflammatory medications, and sometimes surgical debridement or joint replacement if damage is severe.

Q5: Who manages these disorders?
A: Multidisciplinary care involving infectious disease specialists, orthopedic surgeons, and rheumatologists is often required.

Conclusion

ICD10 code M01 ensures proper diagnosis, treatment planning, and follow-up of Direct infections of joint in infectious and parasitic diseases classified elsewhere, supporting rapid intervention to preserve joint function and prevent complications.
