2. Documentation for Standard Commode (E0163)
Assessment: Patient is confined to [specify location] due to [medical condition/limitation]. Patient is unable to access regular toilet facilities because [specific reason]. Standard commode is required for safe toileting needs.
Plan: Prescribed standard commode to allow safe, accessible toileting within patient’s confined area. Patient/caregiver demonstrates understanding of proper use and safety considerations.
3. Documentation for Special Types of Commodes
For Extra Wide/Heavy Duty (E0168):
- Document current weight (must be ≥300 pounds)
- Include date weight was measured (within 1 month of order)

- Document specific need for detachable arms feature:
- Transfer requirements, OR
- Body configuration requiring extra width
For Commode with Seat Lift (E0170, E0171):

Required Documentation Elements

- Face-to-face encounter notes
- Physical assessment findings
- Home environment assessment
- Mobility status evaluation
- Weight (if ordering heavy duty)
2. Standard Written Order (SWO) must include:
- Beneficiary name
- Item description
- Any required specifications (like heavy duty, detachable arms)
- Prescriber signature and date
- NPI number
- Oxygen saturation ≤ 88% OR

Common Documentation Errors to Avoid
❌ Missing specific reason for room/level confinement ❌ No documentation of home environment/toilet accessibility ❌ Missing weight documentation for heavy duty commodes ❌ Incomplete justification for detachable arms ❌ No documentation of inability to use regular toilet facilities ❌ Missing specifications for special features
Practical Documentation Tips
- Room Confinement Example: “Patient confined to bedroom due to severe SOB with minimal exertion from advanced COPD. Unable to ambulate 20 feet to bathroom without severe dyspnea and risk of falls.”
- Level Confinement Example: “Patient confined to first floor of two-story home due to inability to climb stairs following recent hip fracture. No bathroom facilities on first floor. Patient uses walker for all mobility with significant unsteadiness.”
- Heavy Duty Documentation Example: “Patient weighs 325 pounds as measured today. Standard commode weight capacity insufficient. Heavy duty commode required for safe toileting needs.”
- Detachable Arms Documentation Example: “Patient requires sliding board transfers due to left hemiplegia. Detachable arms needed to facilitate safe lateral transfers to/from wheelchair with caregiver assistance.”
