M67: Other disorders of synovium and tendon

M67 refers to Other disorders of synovium and tendon, covering inflammatory, degenerative, or spontaneous disorders affecting the synovial membrane lining joints and the tendons facilitating joint movement. These conditions can significantly impair function and cause chronic pain if untreated.

Symptoms

• Joint swelling and tenderness – Typical of synovitis (M65)
• Crepitus or clicking – Suggestive of tendon sheath inflammation
• Sudden loss of tendon function – Seen in spontaneous ruptures (M66)
• Restricted joint movement – Due to inflammation or mechanical disruption
• Localized pain during movement – Common across all tendon/synovial disorders (M67)

Diagnosis

Diagnosis of Other disorders of synovium and tendon involves physical examination (noting swelling, crepitus, or motion limitations), ultrasound or MRI imaging to detect synovial thickening or tendon tears, and occasionally aspiration or biopsy of synovial fluid to rule out infections or systemic causes.

ICD10 Code Usage

ICD10 code M67 is used by orthopedic surgeons, rheumatologists, sports medicine doctors, and physical therapists for documenting tendon and synovial pathologies, guiding interventions such as steroid injections, tendon repairs, or rehabilitative therapies.

Related Codes

• M65 – Synovitis and tenosynovitis
• M66 – Spontaneous rupture of synovium and tendon

FAQs

Q1: What is ICD10 code M67?
A: It refers to Other disorders of synovium and tendon, describing conditions involving the inflammation, rupture, or dysfunction of synovial membranes and tendons.

Q2: What causes synovitis and tenosynovitis (M65)?
A: Causes include overuse, trauma, inflammatory arthritis, infections, and repetitive strain injuries.

Q3: What is spontaneous tendon rupture (M66)?
A: A sudden, non-traumatic tear of a tendon, often due to degenerative changes, systemic diseases, or prolonged corticosteroid use.

Q4: How are tendon/synovial disorders managed?
A: Treatments include rest, anti-inflammatory medications, physical therapy, corticosteroid injections, and surgical repair if needed.

Q5: Who treats these conditions?
A: Orthopedic surgeons, sports medicine specialists, rheumatologists, and physiotherapists typically manage these conditions.

Conclusion

ICD10 code M67 provides a precise framework for diagnosing and treating Other disorders of synovium and tendon, ensuring timely interventions that restore joint mobility, reduce pain, and prevent further functional impairment.
