Request and Medical Necessity Summary

[Explicit coverage request for PAP device and/or replacement supplies]. [Plain-language diagnosis] (ICD-10: [ICD-10 code]). [Objective diagnostic basis: sleep study type and date]. [Clinical benefit statement if continuation or expected necessity if initial]. Length of need: [12-week trial / Long-term/lifetime].

Diagnoses and Clinical Context

• Symptoms: [Patient-reported symptoms relevant to sleep-disordered breathing with duration: snoring, witnessed apneas, nocturnal gasping/choking, morning headaches, excessive daytime sleepiness, insomnia complaints] (Include only symptoms explicitly documented.)
• Exam/Risk Factors: [BMI], [Neck circumference], [Relevant airway or cardiopulmonary exam findings], [Validated sleepiness scale name, score, and date if performed] (Omit any measurements not documented.)
• Comorbidities: [Relevant conditions strengthening medical necessity: hypertension, cardiovascular disease, stroke history, mood disorder, cognitive impairment] (For continuation letters, include only pertinent comorbidities rather than full problem list.)

Objective Diagnostic Testing

(Populate only with documented results. Do not fabricate or estimate values. Add rows for titration or multiple studies if applicable.)

Study Date	Study Type	Interpreting Clinician	AHI and/or RDI	SpO₂ Nadir	Total Sleep/Recording Time
[Study date]	[In-lab PSG / Home sleep apnea test]	[Interpreting clinician if available]	[Value] [AHI / RDI]	[% nadir if available]	[TST or TRT if available]

(If sleep study values are unavailable, state: "Sleep study report is on file and [attached / available upon request].")

Therapy History and Current Status

[Date PAP therapy initiated or planned]. [Current device mode: CPAP / APAP / Bilevel]. [Mask/interface type in use]. [Tolerance issues encountered if any]. [Interventions attempted: mask refit, humidification adjustments, pressure changes, education]. [Current status and tolerance.] (For initial requests, keep forward-looking and concise. For continuation requests, include key dates and longitudinal summary.)

Prescription — PAP Device and Settings

(Mirror the signed order in the chart. Include only settings actually ordered.)

• Device: [CPAP / APAP / Bilevel without backup rate] (HCPCS: [E0601 / E0470 / code if known])
• Settings: [Fixed pressure in cm H₂O for CPAP / Min–Max range in cm H₂O for APAP / IPAP–EPAP in cm H₂O for bilevel]; Ramp: [setting if specified]; EPR/pressure relief: [setting if specified]; Heated humidification: [on/off and setting if specified]
• Length of need: [12-week trial / Long-term/lifetime]
• Contingency: [Settings pending titration / remote adjustment plan] (Include only if applicable.)

Supplies Requested

[Brief statement explaining need for routine replacement to maintain effective therapy: wear, seal degradation, hygiene, maintenance of therapeutic pressure]. (If requesting quantities exceeding standard intervals, include patient-specific justification: skin breakdown, anatomic leak, recurrent infections, documented damage.)

Item	HCPCS	Quantity	Replacement Interval
[Mask/interface type]	[HCPCS if known]	[Qty]	[Interval]
[Cushions/pillows]	[HCPCS if known]	[Qty]	[Interval]
[Headgear]	[HCPCS if known]	[Qty]	[Interval]
[Tubing]	[HCPCS if known]	[Qty]	[Interval]
[Filters — disposable]	[HCPCS if known]	[Qty]	[Interval]
[Filters — non-disposable]	[HCPCS if known]	[Qty]	[Interval]
[Humidifier water chamber]	[HCPCS if known]	[Qty]	[Interval]
[Chinstrap]	[HCPCS if known]	[Qty]	[Interval]

(Add or remove rows to match the actual order.)

Clinical Benefit and Adherence

(Include for continuation requests. If objective adherence data unavailable, clearly label statements as patient-reported and indicate device download will be obtained. Do not claim threshold adherence without objective data.)

• Subjective improvement: [Patient-reported changes in sleepiness, snoring, witnessed apneas, headaches, sleep quality, mood, cognition, daytime function]
• Objective data: Device download [date range]: average [hours/night], [percent nights used], residual AHI [value], leak [metrics if available]
• Medicare adherence statement: Patient [meets / does not yet meet] adherence threshold (≥4 hours/night on ≥70% of nights in consecutive 30-day period). Clinical re-evaluation occurred [date within days 31–91 of initial trial]. Patient [is / is not] benefiting from therapy. (Include for Medicare or Medicare-like payers.)

Special Scenarios

(Include applicable subsections only. Omit this entire section if none apply.)

Bilevel Justification

• [Prior CPAP/APAP trial details: dates, pressures, interfaces used, duration]
• [Reasons CPAP/APAP was ineffective or not tolerated]
• [Adjustments attempted: interface changes, pressure optimization, humidification, education]
• [Clear rationale for bilevel therapy]

Concurrent Oxygen

• [Statement that OSA is adequately treated on PAP at prescribed settings]
• [Supplemental oxygen qualification pathway and clinical justification]
• [Titration PSG findings if used to qualify oxygen]

Device Replacement

• [Reason for replacement: loss / theft / irreparable damage with incident date / end of reasonable useful lifetime]
• [Request is for: replacement / repair]
• [Existing device make/model and initial dispense date if available]

Attachments

• Diagnostic sleep study report (PSG/HSAT): [attached / available upon request]
