DME Prior Authorization — CPAP Device & Supplies · Humana · FL
PRISM® ANALYSIS REPORT · BASE VARIANT · SAMPLE OUTPUT · March 2026
SITUATION SUMMARY
⚠ COMPLIANCE REQUIREMENT: CPAP coverage under Humana requires a 90-day compliance trial period after initial setup. The device is initially covered as a rental. At day 91, Humana requires documented proof of compliance (device usage data showing ≥4 hours/night on ≥70% of nights over any consecutive 30-day period within the first 90 days) before converting to purchase. Failure to submit compliance data results in denial of continued coverage and the patient may be responsible for the full device cost. This is separate from the initial PA requirement.
A prior authorization request for a CPAP device (E0601) and related supplies was submitted to Humana for a 54-year-old patient with moderate-to-severe obstructive sleep apnea (OSA), confirmed by a qualifying sleep study with an Apnea-Hypopnea Index (AHI) of 22 events per hour. The ordering physician is a board-certified sleep medicine specialist. CPAP DME authorization for Humana follows CMS LCD (Local Coverage Determination) criteria, which Humana applies to both Medicare Advantage and commercial plans. The criteria are objective and documentation-driven — if the sleep study meets the AHI threshold and the qualifying study was conducted in an appropriate setting, approval is straightforward. The most common denial triggers are: wrong sleep study type, sleep study older than 12 months at the time of PA, or missing physician face-to-face evaluation documentation.

[PRACTICE LETTERHEAD] [DATE] To: Humana DME Prior Authorization Department Re: Prior Authorization Request — CPAP Device and Supplies HCPCS: E0601 (CPAP Device), A7030 (Full Face Mask), A7032 (Cushion), A7033 (Nasal Pillows), A7034 (Nasal Interface), A7037 (Tubing), A7038 (Filter — disposable), A7039 (Filter — non-disposable) Patient: [REQUIRED: Patient full name] Date of Birth: [REQUIRED] Member ID: [REQUIRED: Humana member ID] Group Number: [REQUIRED] Dear Humana DME Authorization Department, I am writing to request prior authorization for a CPAP device (E0601) and related supplies for a 54-year-old patient with moderate-to-severe obstructive sleep apnea, confirmed by polysomnography (PSG). This device is medically necessary to treat documented OSA with an Apnea-Hypopnea Index (AHI) of 22 events per hour, which represents moderate-to-severe disease and carries significant cardiovascular and metabolic risk if untreated. QUALIFYING SLEEP STUDY Study Type: Polysomnography (PSG) — attended, in-lab [OR: Home Sleep Apnea Test (HSAT) — if applicable, confirm Humana accepts HSAT for this plan] Date of Study: [REQUIRED — must be within 12 months of PA request] Performing Facility: [REQUIRED: accredited sleep lab name] Interpreting Physician: [REQUIRED: name and credentials] AHI Result: 22 events per hour — moderate-to-severe OSA (AHI ≥15 = moderate; AHI ≥30 = severe) RDI / REI: [REQUIRED if HSAT was used — Respiratory Disturbance Index or Respiratory Event Index] Oxygen Nadir: [REQUIRED: lowest O2 saturation recorded during study, e.g., 84%] % Time SpO2 <90%: [REQUIRED: percentage of study time with oxygen saturation below 90%] PHYSICIAN FACE-TO-FACE EVALUATION Date of face-to-face evaluation: [REQUIRED — must occur within 30 days before or after the qualifying sleep study] Evaluating physician: [REQUIRED: name, specialty, NPI] Clinical findings documented: [REQUIRED: symptoms including excessive daytime sleepiness, snoring, witnessed apneas, morning headaches, cognitive impairment — document at least 2 qualifying symptoms in the office note] Epworth Sleepiness Scale (ESS) score: [REQUIRED: document in office note; ESS ≥10 supports daytime sleepiness] MEDICAL NECESSITY Obstructive sleep apnea with AHI of 22 events per hour represents moderate OSA. Untreated moderate-to-severe OSA is associated with significantly elevated risk of hypertension, cardiovascular disease, stroke, type 2 diabetes, and motor vehicle accidents. CPAP therapy is the gold-standard, evidence-based first-line treatment for moderate-to-severe OSA and is expected to produce meaningful improvement in daytime sleepiness, cognitive function, and cardiovascular risk profile for this patient. This patient meets all qualifying criteria under CMS LCD L33718 and applicable Humana DME coverage policies. CPAP therapy is medically necessary and is expected to result in clinically meaningful benefit. Sincerely, [REQUIRED: Ordering physician full name, credentials, NPI, practice, signature]
RECOMMENDED DOCUMENTATION CHECKLIST
Full polysomnography (PSG) report or qualifying HSAT report — dated within 12 months
→ Must include: AHI (≥5 with symptoms, or ≥15 without symptoms), RDI/REI if HSAT, oxygen nadir, % time SpO2 below 90%, study date, performing facility, and interpreting physician. Humana will not accept a summary — the full report is required.
REQUIRED
Physician face-to-face evaluation note — within 30 days before or after sleep study
→ Office note must document: qualifying OSA symptoms (daytime sleepiness, snoring, witnessed apneas, morning headaches — at least 2), Epworth Sleepiness Scale score, clinical findings, and physician order for CPAP. The face-to-face note is a hard requirement — without it, Humana will deny regardless of AHI.
REQUIRED
Epworth Sleepiness Scale (ESS) score documented in physician office note
→ ESS ≥10 documents excessive daytime sleepiness. Administer and score at the face-to-face visit. ESS score must appear in the office note — not on a separate form that is not part of the medical record.
REQUIRED
Written order / prescription for CPAP from ordering physician
→ Must include: patient name, diagnosis (OSA, ICD-10 G47.33), device type (CPAP — E0601), pressure setting or titration order, date, and ordering physician signature and NPI. Some Humana plans require a separate titration study or auto-titrating CPAP order.
REQUIRED
Confirm DME supplier is in-network with Humana
→ Humana has a contracted DME supplier network. The CPAP must be obtained from an in-network DME supplier — not any supplier the patient or physician chooses. Call Humana member services or check the Humana provider directory to identify contracted DME suppliers in the patient's area before ordering.
REQUIRED
Confirm HSAT vs. PSG acceptance for this specific Humana plan
→ Humana commercial plans generally accept both PSG and HSAT as qualifying studies. Humana Medicare Advantage plans follow CMS LCD L33718 which requires specific conditions for HSAT acceptance. Confirm which study type was performed and whether it qualifies under this patient's specific plan.
RECOMMENDED
Understand the 90-day compliance requirement BEFORE device setup
→ Inform the patient before device setup: Humana requires ≥4 hours/night on ≥70% of nights over any consecutive 30-day period within the first 90 days. Device compliance data (downloaded from the CPAP modem) must be submitted at day 91 to convert from rental to purchase. Non-compliant patients lose coverage and may owe the full device cost.

DECISION LOGIC IDENTIFIED
Humana's CPAP DME coverage follows CMS LCD L33718 criteria, applied to both Medicare Advantage and most commercial plans. The criteria are binary and objective — if each required element is documented, approval is routine. If any element is missing, denial is automatic. The four most common Humana CPAP denial triggers: 1. Missing face-to-face evaluation note — The physician office note documenting the face-to-face evaluation within 30 days of the sleep study is required as a separate document. A sleep study report alone, even with a qualifying AHI, is insufficient. 2. Missing qualifying symptom documentation — The face-to-face note must document at least two qualifying OSA symptoms: excessive daytime sleepiness, loud snoring, witnessed apneas, or morning headaches. If the office note reads "patient referred for sleep study" without symptom documentation, it will not satisfy the criteria. 3. Non-contracted DME supplier — Humana has a contracted supplier network. Patients who obtain CPAP from an out-of-network supplier — even with a valid PA — will receive no coverage. This is one of the most common and most avoidable CPAP coverage failures. 4. 90-day compliance failure — Not a PA issue, but a post-setup coverage issue. Patients who do not use the device ≥4 hours/night on ≥70% of nights during the first 90 days lose ongoing coverage. Counsel the patient before setup — not after.
MISSING INFORMATION OR CRITERIA
▸ Face-to-face evaluation note — Most critical gap. The office note must be from within 30 days before or after the qualifying sleep study, must document qualifying symptoms, and must contain the physician's clinical assessment and CPAP order. Without this note, Humana will deny regardless of AHI. ▸ Qualifying symptoms not documented — Daytime sleepiness, snoring, witnessed apneas, and morning headaches must be explicitly listed in the face-to-face note. Implied or assumed symptoms do not satisfy the criteria engine. ▸ Epworth Sleepiness Scale score — Must be documented in the office note, not on a separate form. ESS ≥10 is the threshold for documented excessive daytime sleepiness. ▸ Written CPAP order — A prescription with pressure settings or an auto-titrating CPAP order must accompany the PA request. The DME supplier requires this order to process the authorization and set up the device. ▸ DME supplier confirmation — The patient must obtain the device from a Humana-contracted supplier. This must be confirmed before ordering — not discovered after the device is delivered and the claim is denied.
MOST LIKELY SUCCESSFUL NEXT STEP
Schedule the face-to-face evaluation if not yet completed. This single visit closes four of the six open gaps: qualifying symptom documentation, ESS score, face-to-face requirement, and CPAP order can all come from one well-documented office visit. Then confirm the DME supplier network status before ordering. Call Humana member services: "I need a list of contracted DME suppliers for CPAP equipment in [patient zip code]." Submit the complete package: full PSG report, face-to-face office note with symptoms and ESS score, written CPAP order, and DME supplier confirmation. Humana's routine DME PA response is typically 3–5 business days.
ALTERNATE PATHWAYS
OPTION 1 · If Denied — Appeal with Missing Documentation Added
Most Humana CPAP denials are documentation denials, not clinical denials. If the PA is denied, obtain whatever document was missing and file a Level 1 appeal with the complete package. CPAP appeals with complete documentation routinely succeed. The clinical case — AHI 22 with qualifying symptoms — is not in dispute. The appeal is purely a documentation completion exercise.
OPTION 2 · Auto-Titrating CPAP (APAP) as Alternative Device
If a fixed-pressure CPAP titration study has not been completed, an auto-titrating CPAP (APAP — E0601 with auto-titration feature) can be ordered without a separate titration study. APAP adjusts pressure automatically and is clinically equivalent to fixed-pressure CPAP for most OSA patients. Humana covers APAP under the same HCPCS code (E0601) with the same PA requirements. This avoids the need for a second in-lab study.
OPTION 3 · If Compliance Data Fails at 90 Days — Appeal with Clinical Documentation
If the patient fails the 90-day compliance threshold (less than 4 hours/night on less than 70% of nights), Humana will deny continued coverage. Before accepting the denial, file an appeal with: (1) a physician note documenting clinical barriers to compliance (mask fit issues, claustrophobia, pressure intolerance) and the clinical interventions taken to address them; (2) updated compliance data if usage improved after intervention; and (3) documentation of DME supplier follow-up to troubleshoot compliance barriers. Non-compliance with a documented clinical cause and remediation effort is frequently overturned on appeal.
ESCALATION GUIDANCE
Level 1 — Complete Documentation, Submit Close all documentation gaps at the face-to-face visit. Confirm in-network DME supplier. Submit complete package. CPAP DME with complete documentation is a routine approval. Level 2 — Level 1 Appeal with Missing Document If denied on documentation grounds: identify the specific missing element from the denial letter, obtain it, and file a Level 1 appeal with the complete package. Do not refile — appeal the denial. Refiling resets the clock and may create a duplicate claim issue. Level 3 — External IMR (Florida) If Level 1 appeal is denied: file for Independent Medical Review. CPAP denials for AHI ≥15 with qualifying symptoms and a physician order are extremely difficult to sustain at the IMR level — the clinical evidence for CPAP necessity in moderate-to-severe OSA is overwhelming and well-established. Level 4 — Florida OIR Complaint If Humana fails to respond within required timelines or denies a clinically appropriate CPAP without clear documentation grounds, file a complaint with the Florida Office of Insurance Regulation.
NAVIGABILITY OBSERVATION
This case is highly navigable. CPAP DME authorization for moderate-to-severe OSA with an AHI of 22 is one of the most straightforward coverage pathways in DME — when the documentation is complete. Humana's criteria are objective and binary. The clinical case is not in dispute. The current submission has documentation gaps — face-to-face note, symptom documentation, ESS score, written order — but every gap is closable in a single well-documented office visit. This is an administrative problem, not a clinical one. Close the gaps, confirm the DME supplier, submit the complete package. This should not require an appeal. Do it right the first time and the patient gets their device without delay.
