Can You Get SSDI for Polymyositis?

TL;DR: Yes. Polymyositis is an inflammatory muscle disease that causes progressive proximal muscle weakness without the skin rash seen in dermatomyositis. Like dermatomyositis, it has its own SSA listing (14.05) which specifically addresses this condition. If polymyositis causes significant weakness in your shoulders, hips, or neck, impairs your swallowing, or affects your breathing, you can qualify for SSDI.

Polymyositis attacks skeletal muscles, causing them to become inflamed and weak. The weakness typically develops gradually over weeks to months and affects the muscles you use for everyday activities: lifting your arms, climbing stairs, getting up from a seated position, and carrying objects. Unlike some conditions where the question is whether you will recover, polymyositis is chronic and often requires lifelong immunosuppressive treatment.

SSA Listing for Polymyositis

SSA ListingConditionKey Requirements
14.05Polymyositis and dermatomyositisProximal muscle weakness documented by exam, plus impaired swallowing, respiratory impairment, or diffuse calcinosis

To meet this listing, you need:

  1. Documented proximal muscle weakness on physical examination, AND
  2. At least one of: difficulty swallowing (dysphagia), impaired respiration due to intercostal or diaphragm muscle weakness, or diffuse calcinosis with joint or limb impairment

Medical Evidence the SSA Needs

  • Rheumatology or neurology diagnosis
  • Elevated muscle enzymes: CK, aldolase, LDH, AST
  • EMG showing myopathic pattern (short duration, low amplitude motor unit potentials)
  • Muscle biopsy showing endomysial inflammation (the gold standard diagnostic test)
  • MRI of muscles showing edema pattern
  • Myositis-specific and myositis-associated antibody panel
  • Manual muscle testing with specific grades for each muscle group
  • Pulmonary function tests (FVC, MIP, MEP) if respiratory muscles are affected
  • Modified barium swallow study if swallowing is affected
  • Treatment records: prednisone, methotrexate, azathioprine, IVIG, rituximab

RFC for Polymyositis

LimitationWork Impact
Shoulder weaknessCannot reach overhead, lift objects above waist level, or carry more than a few pounds
Hip weaknessDifficulty standing from seated position, climbing stairs, walking distances
Neck weaknessCannot hold head up for extended periods, difficulty looking at screens or documents
Swallowing difficultyChoking risk, slow eating, weight loss, aspiration pneumonia risk
Respiratory weaknessShortness of breath with minimal exertion, reduced endurance
Medication effectsSteroid side effects, immunosuppression-related infections, fatigue

Common Denial Reasons

  • CK levels normal on treatment. Enzyme normalization does not equal strength recovery. Document weakness on physical examination regardless of lab values.
  • Improvement noted on treatment. Partial improvement does not mean you can work. Document remaining weakness and its functional impact.
  • No biopsy or EMG. Without objective testing, the diagnosis may be questioned. These tests strengthen your claim significantly.
  • Distal weakness not documented. If your hands are also weak (which happens in some polymyositis subtypes), make sure it is documented.

Compassionate Allowance

Polymyositis is not on the Compassionate Allowance list.

Function Report Tips

  • Describe specific activities you cannot do: raising arms to wash hair, getting up from a low chair, carrying grocery bags
  • Detail how weakness has progressed over time
  • Explain swallowing or breathing difficulties if present
  • List all medications and their side effects on your daily function
  • Describe the effort required for basic self-care activities
  • Note how quickly you fatigue during any sustained activity
