Frequently Asked Questions
What are the signs of sleep apnea in seniors?
Common signs in seniors: loud snoring (reported by bed partner), gasping or choking during sleep, waking unrefreshed despite adequate hours, excessive daytime sleepiness, morning headaches, difficulty concentrating, frequent nighttime urination, and depression or irritability. Many seniors attribute these symptoms to normal aging. If you have 3 or more of these symptoms, discuss sleep apnea screening with your doctor.
How is sleep apnea diagnosed?
Sleep apnea is diagnosed through a sleep study (polysomnography). Medicare Part B covers both: in-lab sleep studies at a certified sleep center, and home sleep apnea tests (HSAT) — small portable devices worn at home overnight. Home tests are appropriate for patients with high likelihood of obstructive sleep apnea without other complex sleep disorders. Your doctor orders the test; Medicare covers it at 80% after the Part B deductible.
Does Medicare cover CPAP machines?
Yes — Medicare Part B covers CPAP machines and supplies as durable medical equipment when sleep apnea is diagnosed and CPAP is prescribed. Coverage is provided through a 3-month trial period initially — if you're compliant with CPAP use (4+ hours per night on 70% of nights during the first 30 days), Medicare continues coverage. You pay 20% coinsurance ($0 with Medigap Plan G). CPAP supplies (masks, filters, tubing) are covered on a regular replacement schedule.
What is the AHI and what number indicates sleep apnea?
AHI (Apnea-Hypopnea Index) measures the number of breathing pauses per hour of sleep. Classification: Mild sleep apnea: AHI 5–14. Moderate: AHI 15–29. Severe: AHI 30+. Medicare requires an AHI of 15 or greater (moderate-severe) for CPAP coverage, OR an AHI of 5–14 with documented daytime sleepiness or cardiovascular comorbidity.
Are there alternatives to CPAP for sleep apnea?
Yes — for mild-to-moderate obstructive sleep apnea: Mandibular Advancement Devices (MADs) are oral appliances that reposition the jaw to keep the airway open. Medicare covers custom-fitted MADs as DME when CPAP is not tolerated. Positional therapy (devices that prevent sleeping on the back) helps some patients with position-dependent apnea. Weight loss can significantly reduce or resolve sleep apnea in overweight patients. Surgical options exist for specific anatomical causes.
Sleep apnea affects an estimated 20–30% of seniors — and the majority are undiagnosed. It is not just a snoring problem: untreated sleep apnea directly drives hypertension (in 50% of cases), increases heart attack risk by 23%, raises stroke risk, accelerates cognitive decline, worsens diabetes control, and contributes to depression. Medicare covers both the diagnosis and the treatment. The barrier is simply not recognizing the symptoms.
Why Sleep Apnea Is Different in Seniors
Sleep apnea in seniors frequently presents differently than in younger adults. The classic symptom of loud snoring is less prominent — many older adults with significant apnea are surprisingly quiet. Daytime symptoms dominate: fatigue that doesn't improve with rest, cognitive fog, depression, frequent nighttime urination (nocturia — apnea events trigger urination reflexes), and morning headaches. These are all commonly attributed to aging itself, delaying diagnosis by years.
The Health Consequences of Leaving It Untreated
- Blood pressure: Sleep apnea is the most common secondary cause of hypertension. Each apnea event spikes cortisol and adrenaline. Treating apnea reduces systolic blood pressure by 2–5 mmHg — sometimes reducing or eliminating the need for antihypertensive medication.
- Heart disease: Repeated oxygen desaturations stress the heart. Untreated moderate-severe sleep apnea increases cardiovascular event risk by 23%.
- Cognition: Oxygen desaturation during sleep directly damages the hippocampus. Studies show accelerated cognitive decline in untreated sleep apnea, reversed with CPAP treatment.
- Diabetes: Sleep apnea worsens insulin resistance independently of weight. Treating apnea improves A1c in diabetics with concurrent sleep apnea.
- AFib: Sleep apnea is present in 50%+ of patients with atrial fibrillation. It triggers AFib episodes and reduces ablation success rates in untreated patients.
Getting Diagnosed Through Medicare
Tell your doctor you're concerned about sleep apnea. They'll likely order a home sleep apnea test (HSAT) — a small device you wear at home for one or two nights. Medicare Part B covers it at 80% after the deductible. The device measures oxygen levels, breathing effort, and airflow overnight. Results are reviewed by a sleep specialist who calculates your AHI and determines severity.
CPAP — Medicare Coverage Details
CPAP (Continuous Positive Airway Pressure) is the gold standard treatment. Medicare covers it as DME after a qualifying diagnosis and prescription. The coverage process:
- Qualifying diagnosis (AHI ≥15, or AHI 5–14 with documented symptoms)
- CPAP is prescribed with specific pressure settings
- Obtain from a Medicare-enrolled DME supplier
- 3-month trial with compliance monitoring — must use 4+ hours/night on 70%+ of nights
- If compliant, Medicare continues coverage indefinitely with ongoing supply replacements
CPAP supply replacement schedule under Medicare: masks every 3 months, cushions every month, filters every month, tubing every 3 months, headgear every 6 months. You can receive replacements on this schedule — call your DME supplier.
- If you have 3+ symptoms, discuss sleep apnea screening with your doctor — bring it up, don't wait
- Home sleep apnea tests are covered by Medicare — no overnight stay required
- Use CPAP 4+ hours per night on 70%+ of nights during the 3-month trial — required for continued coverage
- Replacing CPAP supplies is covered — call your DME supplier every 3 months
- If CPAP isn't working for you, ask about mandibular advancement devices — also Medicare-covered
