CPT code 95806: Home sleep apnea testing billing guide

Key takeaways

CPT code 95806 describes an unattended home sleep apnea test that records heart rate, oxygen saturation, respiratory airflow, and respiratory effort at once.

Medicare covers 95806 primarily for obstructive sleep apnea (G47.33), and a non-covered ICD-10 pairing is the most common denial trigger.

The 2026 Medicare non-facility rate runs roughly $91 to $107, varying by MAC region and by whether interpretation is billed separately.

A device recording only two or three channels belongs on 95801, so the chart has to name the device model and its channel count.

Pabau’s claims management software checks CPT and ICD-10 pairings inside the billing workflow, so errors surface before the claim leaves the practice.

CPT code 95806 is the billing code for an unattended home sleep apnea test (HSAT) that records four parameters at once. Those parameters are heart rate, oxygen saturation, respiratory airflow, and respiratory effort. A qualified physician interprets the download afterward, and that interpretation is part of the code.

Denials on this code rarely come from the study itself. They come from the record built around it. The physician order, the ICD-10 pairing, and the signed interpretation report stop more 95806 claims than any coding subtlety.

This guide covers the code definition, the four required channels, and the ICD-10 codes that support medical necessity. It also covers the 2026 Medicare fee schedule, documentation and prior authorization requirements, modifier selection, and the denial patterns worth tracking.

What CPT code 95806 covers

CPT code 95806 describes a sleep study, unattended, with simultaneous recording of heart rate, oxygen saturation, respiratory airflow, and respiratory effort.

Effort is usually captured as thoracoabdominal movement. The American Medical Association (AMA) maintains the CPT code set and files 95806 under sleep medicine testing.

“Unattended” means no sleep technician is present during the recording. The patient wears a portable monitoring device at home overnight. The raw data is downloaded afterward and interpreted by a qualified physician. That is what separates 95806 from attended in-lab codes such as 95810 and 95811.

The American Academy of Sleep Medicine (AASM) classifies the study 95806 describes as a Type III home sleep apnea test. Type III devices record at least four channels, which is what the 95806 descriptor requires. Type IV devices record only two or three channels, and those studies bill under 95801 rather than 95806.

The four required recording parameters

Every 95806 claim requires simultaneous recording of exactly these four parameters. Missing even one makes the procedure non-billable under this code.

CPT 95806 does not include EEG, EMG, or eye-movement recording. If those channels are required, the procedure moves to 95807 or a higher polysomnography code. The AMA descriptor draws the line there, and CMS LCD article A57496 applies the same boundary in coverage policy.

CPT 95806 vs. related sleep study codes

Sleep medicine billing involves a family of closely related codes. Billing 95806 when 95800 or 95801 applies is a common error. The comparison below captures what separates them.

The decision turns on the channel count and the setting. A device that records EEG or EMG in a supervised facility puts you in 95810 or 95811 territory. A device that omits respiratory effort puts you in 95801.

ICD-10 diagnosis codes that support medical necessity

Pairing 95806 with a non-covered ICD-10 code is the single most common reason these claims are denied. Medicare’s coverage policy, set out in CMS LCD article A57496, recognizes obstructive sleep apnea and related sleep disorders as the primary covered indications.

Snoring (R06.83) and insomnia (G47.00) do not support medical necessity for HSAT on their own. If a patient presents with snoring plus suspected OSA, document the clinical suspicion so the order carries G47.30 or G47.33.

Most 95806 claims are built on G47.33, so it is worth knowing which clinical findings that code expects in the note. Covered code lists also change, so check your MAC’s current Local Coverage Determination each year.

Medicare reimbursement and the 2026 fee schedule

Medicare pays CPT 95806 under the Physician Fee Schedule. Rates differ between facility and non-facility settings. They also differ between the technical component, which is the recording, and the professional component, which is the physician interpretation. Check current figures with the CMS Physician Fee Schedule Look-Up Tool.

These are CY2026 national averages. Confirm the rate for your own MAC region before you submit. Geographic adjustment through locality factors shifts payment by roughly 10% to 20% either side of the national figure.

The split between the two components matters when a contracted physician reads the studies. Billing only the technical component gives up roughly 40% of the global fee. Price that arrangement with the interpreting physician before you sign it.

Documentation requirements for a clean 95806 claim

An incomplete medical record is the second most common denial trigger after ICD-10 mismatches. Medicare and most commercial payers want all of the following in place before a 95806 claim will pay.

• Signed physician order: A written or electronic order naming the clinical indication. It must be in the record before the device is placed.
• Clinical documentation of medical necessity: Notes showing symptoms, BMI, and comorbidities that support testing. Witnessed apneas, daytime sleepiness, and an Epworth Sleepiness Scale score all count here.
• Device information: The portable monitoring device used, its channel configuration, and confirmation that all four required parameters were recorded.
• Date and duration of recording: The dates the device was worn and the total recording time. Many MACs set a minimum valid recording duration.
• Interpretation report: A signed, dated physician report giving the AHI or RDI result, the device used, and the clinical conclusion. It must exist separately from the raw data download.
• Ordering provider credentials: The ordering physician must be licensed to order HSAT under state law and must not be excluded from Medicare participation.

Complete each element at the time of service. Reconstructing a record after a denial takes far longer than capturing it at chart closure, and payers can treat late additions as unsupported.

Prior authorization requirements

Medicare does not currently require prior authorization for CPT 95806 in most MAC jurisdictions. Local Coverage Determinations still impose coverage criteria that work as de facto authorization requirements. Commercial payer rules vary widely, so verify each plan before the study is scheduled.

Record the payer’s requirement at the scheduling stage rather than at billing. By the time a biller finds the missing authorization, the device has already been worn and the service cannot be undone.

When prior authorization is required, payers typically ask for the clinical notes documenting OSA symptoms, the ordering physician’s details, and the planned device type. Some also want a note on failed conservative treatment. Criteria change by plan year, so record the PA reference number and approval date before the device is dispensed.

Which modifiers apply to 95806

Modifier selection turns on one question. Does the same entity perform both the technical recording and the professional interpretation, or are those two jobs split between separate billing entities?

Billing both TC and 26 from the same provider on one claim flags as unbundled. Modifier requirements follow the billing relationship on the date of service, not the date of submission. Check with a certified coder when your arrangement with an interpreting physician changes mid-year.

Common billing errors and denial reasons

Five triggers account for the majority of 95806 rejections. Each one has a root cause that can be fixed upstream of the claim, which is what the table below sets out.

Reviewing the medical billing denial codes on your 95806 remittances maps each CARC back to one of these root causes. All five are created before the claim is built, at a specific point in the workflow. The sequence below shows where each check belongs.

How Pabau prevents 95806 denials before submission

The documentation failures and ICD-10 mismatches behind most 95806 denials happen long before the claim reaches a clearinghouse. They happen at scheduling, at device dispense, and at chart closure. Software that connects those three points cuts the number of places an error can start.

Pabau is practice management software built for medical and aesthetic practices. Its claims management software holds CPT and ICD-10 pairing logic inside the billing workflow. A mismatched pair is flagged before submission, so the G47.33 requirement is checked at the claim rather than discovered on a remittance weeks later.

The ordering workflow carries the other half of the job. Required fields for the signed order, the clinical indication, and the device configuration can sit in the appointment itself. A device then cannot be dispensed against an incomplete chart.

Electronic remittance data flows back into the same record after submission. That keeps the denial log current without manual reconciliation, so you can see which of the five triggers your practice actually hits.

Conclusion

Selecting CPT 95806 is straightforward once the channel count is settled. Almost every denial on the code comes from something the practice controls: the order, the diagnosis pairing, the device configuration, or the signed report.

That makes 95806 a workflow problem with a workflow answer. Move each check to the point where it is still cheap, and the denial rate falls without anyone learning a new coding rule. The trade-off is an ordering workflow that carries more required fields than clinicians usually like.

Start with the two checks that fail most often: the ICD-10 pairing and the signed order. Book a demo to see how Pabau validates both before a 95806 claim leaves the practice.
