Comorbidity must be documented by physician (MD, DO, NP, PA) in H&P, progress note, or consultation note
✅ What to Document:
❌ What Doesn't Count:
Patient must receive ongoing treatment for the comorbidity during rehabilitation stay
✅ Examples of Active Treatment:
❌ What Doesn't Count as Active Treatment:
Comorbidity must affect therapy participation, progress, or length of stay
✅ Examples of Clinical Impact:
❌ What Doesn't Show Impact:
If ANY of the three criteria is missing, the comorbidity CANNOT be coded for IRF-PAI. Missing documentation = lost reimbursement and potential audit risk.
✅ Good: "Lasix 40mg PO given at 0800 for CHF management. Daily weight 165 lbs (down 2 lbs from yesterday). I&O: +500mL. Lungs clear, no edema."
❌ Poor: "Medications given as ordered."
✅ Good: "Blood glucose 180 mg/dL pre-breakfast. 4 units Humalog given per sliding scale. Glucose rechecked before therapy at 1000: 145 mg/dL. Patient cleared for therapy."
❌ Poor: "Blood sugar checked."
✅ Good: "Patient required 2L O2 during therapy due to COPD. Therapy session limited to 30 minutes due to dyspnea and fatigue. SpO2 88% on room air, improved to 94% on 2L."
❌ Poor: "Patient on oxygen."
✅ Good: "Stage 3 pressure ulcer on sacrum, 4cm x 3cm x 1cm depth. Wound care performed with Aquacel dressing change. Wound prevents supine positioning during therapy, requiring side-lying modifications."
❌ Poor: "Wound care done."
✅ Good: "Patient's COPD exacerbation limits activity tolerance. Required 3 rest breaks during 45-min PT session. SpO2 dropped to 88% with ambulation, improved with rest and 2L O2. Gait training modified to shorter distances."
❌ Poor: "Patient has COPD."
✅ Good: "Patient's severe anemia (Hgb 7.0) causes significant fatigue. Unable to complete full OT session - tolerates only 20 minutes before exhaustion. ADL training limited to essential tasks only."
❌ Poor: "Patient fatigued."
✅ Good: "Patient's acute CHF exacerbation on Day 3 resulted in 2 days of missed therapy due to dyspnea and medical management. Progress toward discharge goals delayed by approximately 3-4 days."
❌ Poor: "Patient missed therapy."
✅ Good: "Patient's diabetes requires glucose monitoring before each therapy session. Session delayed 15 minutes today due to hypoglycemia (glucose 65). Patient given juice, rechecked at 95, then cleared for therapy."
❌ Poor: "Patient has diabetes."
Situation: Patient has Type 2 Diabetes documented in H&P
Question: What additional documentation is needed for IRF-PAI coding?
Situation: Nurse notes: 'Patient has CHF'
Question: Is this documentation sufficient for IRF-PAI?
Situation: Patient on Lasix 40mg daily, no other CHF documentation
Question: Can you code CHF based on medication alone?
Situation: Therapist notes: 'Patient has COPD per history'
Question: Is this adequate physician documentation?
Situation: Patient has 'history of MI' in H&P from 5 years ago
Question: Can this be coded as a current comorbidity?
