L24.9 - Irritant contact dermatitis, unspecified cause

Clinical Definition

A villonodular synovitis (PVNS) is a benign but locally aggressive tumor-like condition where the synovial membrane that lines joints, bursae, or tendon sheaths undergoes abnormal growth and produces nodules. The condition results in inflammation and overgrowth of the synovial tissue.

Documentation Requirements

• Anatomical location (specific joint affected)

• Laterality (right, left, bilateral)

• Type/classification

  • Localized vs. diffuse

  • Pigmented vs. non-pigmented

• Activity status (active vs. inactive)

• Acuity (acute, chronic, recurrent)

• Associated symptoms or complications

• Previous surgical interventions (if any)

Common Synonyms

• Giant cell tumor of tendon sheath

• PVNS (Pigmented Villonodular Synovitis)

• Tenosynovial giant cell tumor

• Synovial xanthomatosis

• "Joint lining disease"

Scribing.io Automation

The AI scribe automatically detects and captures:

• Keywords indicating villonodular synovitis or its synonyms

• Anatomical descriptors for affected joints

• Laterality terms

• Descriptors of extent (localized/diffuse)

• Pigmentation status

• Associated symptoms and functional impact

• Treatment plans and surgical interventions
