Required clinical questions:

• What is the qualifying diagnosis and is there a face-to-face encounter documented within the required timeframe (90 days before or 30 days after SOC)?
• Why is the patient homebound (specific medical condition causing inability to leave home)?
• What is the patient's current functional status in the home environment?
• Who is in the home (caregiver availability, other household members)?
• What is the home environment (single story/multi-level, stairs, bathroom setup, clutter/hazards)?
• What therapy services are ordered (PT, OT, SLP) with frequency and duration?

Required documents:

• Physician face-to-face encounter documentation (within required timeframe)
• Home health certification and plan of care (CMS-485) signed by physician
• Hospital discharge summary or referring provider documentation
• Current medication list
• OASIS-E assessment (completed at SOC, resumption of care, recertification, transfer, discharge)
• Insurance verification with home health benefit status

Step 1 — Establish and Document Homebound Status

Homebound status is the threshold requirement for Medicare home health eligibility. Document at EVERY visit.

CMS homebound criteria (patient must meet at least one):

Criterion 1 — Leaving home requires considerable and taxing effort due to:

• Need for supportive devices (walker, wheelchair, crutches, cane)
• Need for special transportation or assistance of another person to leave
• Condition that is such that leaving home is medically contraindicated

Criterion 2 — The patient has a condition due to illness or injury that restricts ability to leave the home except for:

• Medical appointments
• Adult day care for therapeutic purposes
• Unique or infrequent events (religious services, family events)
• Short, non-routine absences (barber, walk around the block)

How to document homebound status (every visit): "Patient is homebound due to [specific medical condition]. [Patient specific limitations]: requires rolling walker and supervision for all ambulation due to impaired balance (Berg 28/56, TUG 32 seconds). Leaving the home requires assistance of one person for car transfer and ambulation from house to car (3 steps without railing). Absences from home are limited to physician appointments approximately 2x/month. Attempts to leave home produce significant fatigue and shortness of breath (Borg 6/10 after 100 feet)."

Red flags for homebound denial:

• Documentation states patient "walks in the neighborhood daily"
• Patient drives independently to appointments regularly
• Homebound language is generic/copy-pasted without patient-specific details
• No functional data supporting the homebound claim

Step 2 — Complete OASIS-E Assessment Accurately

OASIS-E (Outcome and Assessment Information Set) drives PDGM payment and quality measures:

Key OASIS-E functional items (Section GG):

• GG0130: Self-care (eating, oral hygiene, toileting hygiene, shower/bathe self, UB dressing, LB dressing, putting on/taking off footwear)
• GG0170: Mobility (roll left/right, sit to lying, lying to sitting on side of bed, sit to stand, chair/bed to chair transfer, toilet transfer, car transfer, walk 10 feet, walk 50 feet with two turns, walk 150 feet, walking 10 feet on uneven surfaces, 1 step/curb, 4 steps, 12 steps, picking up object, wheelchair mobility)

GG scoring scale (6-point):

• 06: Independent
• 05: Setup or clean-up assistance
• 04: Supervision or touching assistance
• 03: Partial/moderate assistance
• 02: Substantial/maximal assistance
• 01: Dependent
• 07: Refused
• 09: Not applicable
• 10: Not attempted due to environmental limitations
• 88: Not attempted due to medical condition or safety concerns

OASIS accuracy requirements:

• Score based on actual observation when possible, supplemented by patient/caregiver report
• Score the patient's usual performance, not best day performance
• Complete all items; do not leave blank (will reject on submission)
• SOC OASIS must be completed within 5 calendar days of SOC date
• Discharge OASIS within 2 calendar days of discharge

Step 3 — Document Skilled Therapy Need at Every Visit

CMS requires that every therapy visit demonstrate skilled need — the service requires the skills of a licensed therapist:

What constitutes skilled therapy (document this):

• Assessment and reassessment of the patient's condition that requires clinical judgment
• Teaching compensatory techniques, exercise programs, or safety strategies that require therapist expertise
• Therapeutic exercise or neuromuscular re-education requiring therapist judgment for progression
• Home safety assessment and modification that requires clinical expertise
• Design, modification, or supervision of a maintenance program that requires therapist-level skills

What does NOT constitute skilled therapy:

• Routine exercise repetition that a caregiver could perform after instruction
• General supervision of activities the patient can perform safely
• Social visits or general wellness checks
• Treatments that are not producing measurable functional improvement and have not been modified

Visit note template elements (every visit):

1. Homebound status justification (specific to that day's observation)
2. Skilled intervention performed with clinical rationale
3. Patient response to intervention (objective data: distance, time, assist level, RPE)
4. Progress toward goals (reference specific short-term and long-term goals)
5. Plan for next visit including intervention modifications

Step 4 — Manage the 60-Day Certification Period

Certification timeline:

• Initial certification: Face-to-face encounter + physician-signed plan of care
• Recertification: Every 60 days for continued services; physician must recertify
• Recertification requires: continued homebound status, continued skilled need, and continued progress toward goals

Frequency and duration justification:

• Typical home health PT/OT: 1-3 visits/week for 4-8 weeks
• Document why the frequency is needed: "2x/week PT visits required due to fall risk (2 falls in past month), need for progressive balance training that cannot be safely performed without therapist present, and ongoing gait training for stair negotiation (patient has 4 steps to enter home without railing)"
• Reduce frequency as patient improves — payers expect a tapering pattern

Progress reassessment:

• Formal reassessment at least every 30 days (per CMS requirements for therapy progress reporting)
• Document measurable change (e.g., "TUG improved from 32 sec to 24 sec; ambulation distance increased from 100 ft to 350 ft with rolling walker; Berg improved from 28 to 38")
• If no measurable progress over two consecutive reassessment periods, document:
  • Reason for lack of progress (medical setback, hospitalization, non-compliance)
  • Modifications made to intervention approach
  • Whether continued therapy is indicated or whether a maintenance program is appropriate

Step 5 — Plan Discharge and Transition to Community

Discharge criteria (must be defined in initial plan of care):

• Functional goals met (specific benchmarks)
• Patient safe for independent home exercise program
• Homebound status no longer meets criteria (patient can access outpatient therapy)
• Patient/caregiver demonstrate competence with home program
• Equipment and home modifications in place and functioning
• Follow-up appointments scheduled

Discharge OASIS-E:

• Complete within 2 calendar days of discharge
• Score reflects status at discharge, not at SOC
• Improvement in GG scores from SOC to discharge demonstrates program effectiveness

Transition options:

• Discharge to independent home program with written HEP
• Transition to outpatient therapy if homebound status resolves
• Referral to community exercise program (fall prevention, wellness)
• Maintenance therapy program (skilled therapist develops plan, aide or patient continues) — document skilled need for program design

Checkpoint B — Pre-Finalization Review

Before finalizing home health rehabilitation documentation:

• Homebound status documented with patient-specific medical justification at every visit
• OASIS-E completed accurately at all required time points (SOC, recertification, discharge)
• Face-to-face encounter documented within required timeframe
• Physician-signed plan of care (CMS-485) on file
• Every visit note demonstrates skilled therapy need
• Measurable goals with standardized outcome measures established
• Progress toward goals documented at minimum every 30 days
• Frequency and duration justified with clinical rationale
• Home safety assessment completed and documented
• Discharge plan with HEP, equipment, and follow-up defined

Quality Audit

• Homebound status language is patient-specific and includes functional data (not template language)
• OASIS-E GG items scored using correct 6-point scale with all items completed
• SOC OASIS within 5 days of SOC; Discharge OASIS within 2 days of discharge
• Skilled need documented at every visit (not just exercise supervision)
• Visit frequency matches clinical need and shows appropriate tapering
• Standardized outcome measures (TUG, Berg, 6MWT, gait speed) used at intake and discharge
• All [VERIFY] flags resolved or escalated to physician
• CMS-485 plan of care matches actual services delivered
• Recertification completed timely for each 60-day period
• Documentation would withstand CMS audit scrutiny (ADR-ready)

Guidelines

• Homebound status must be documented at EVERY visit — not just the initial evaluation; generic or copy-pasted language is a red flag for auditors
• OASIS-E accuracy directly affects PDGM payment grouping and quality star ratings — invest time in accurate scoring
• Skilled therapy requires a therapist's judgment, not just a therapist's presence — document what clinical decision-making occurred at each visit
• A patient can be homebound AND occasionally leave the home for medical appointments or brief outings — these do not disqualify homebound status
• Therapy must produce measurable functional improvement; maintenance therapy requires a separate documented rationale (Jimmo v. Sebelius settlement)
• The Jimmo settlement clarified that Medicare covers skilled maintenance therapy when the skills of a therapist are required to maintain function or prevent decline — document the skilled need
• Do not reduce OASIS functional scores to increase payment — this constitutes fraud
• Therapy assistants (PTA/COTA) in home health are subject to 15% payment reduction under PDGM — document supervision per state practice act
• Fall prevention and home safety assessment are among the highest-value home health therapy interventions — document findings and modifications at every visit
• Coordinate with home health nursing and aide services to avoid duplicative documentation and ensure consistent care delivery
