Documentation

Best-practice checklist

  • ✓Left upper arm pain: Onset, duration, character
  • ✓Location and radiation of arm pain
  • ✓Aggravating and relieving factors
  • ✓Associated symptoms (e.g., numbness, tingling)
  • ✓Physical exam: Palpation, ROM, neurovascular
Mitigation

Best-practice tips

  • 01Thorough HPI: Document pain onset, location, quality, radiation, associated symptoms. ICD-10 M79.602
  • 02Rule out cardiac causes: EKG, cardiac enzymes if indicated. CDI query for chest pain. HCC 225
  • 03Neuro exam: Assess for cervical radiculopathy, peripheral neuropathy. ICD-10 G54.0, G58.9
  • 04MSK exam: Evaluate shoulder, elbow, wrist ROM, strength. Document findings. CPT 99204, 99214
  • 05Image if red flags: X-ray, MRI for fracture, soft tissue injury. Compliance with imaging guidelines
Clinical Decision Support

Step-by-step checklist

  1. 1

    Rule out cardiac causes: ECG, troponin (ICD-10 I20-I25)

  2. 2

    Assess for cervical radiculopathy: Spurling's test, imaging (ICD-10 M50-M54)

  3. 3

    Evaluate for peripheral neuropathy: Sensory exam, EMG (ICD-10 G54-G64)

  4. 4

    Check for musculoskeletal injury: ROM, palpation (ICD-10 S40-S49)
