What This Code Means

Juvenile dermatomyositis (a childhood muscle and skin disease) without documentation of which organs are involved.

Coding Tips

  • This code is used when juvenile dermatomyositis is diagnosed but organ involvement has not been assessed or documented
  • Review clinical notes to determine if respiratory involvement, myopathy, or other organ involvement should be coded instead

Clinical Significance

Juvenile dermatomyositis is a rare but serious autoimmune condition affecting children that can lead to significant morbidity if untreated. The unspecified organ involvement suggests need for comprehensive evaluation to identify all affected systems and optimize treatment.

Documentation Requirements

  • Confirmed diagnosis of juvenile dermatomyositis
  • Patient age documentation confirming juvenile onset
  • Characteristic skin manifestations (heliotrope rash, Gottron's papules)
  • Evidence of muscle involvement or weakness
  • Laboratory studies (muscle enzymes, inflammatory markers)
  • Documentation that organ involvement is present but unspecified
  • Treatment plan including immunosuppressive therapy
  • Monitoring plan for disease progression and complications
