Sleep medicine billing for practices, sleep labs and groups: home and in-lab sleep studies, professional and technical splits, the visits that start and keep PAP therapy covered, and oral appliance and other treatment referrals, worked inside the software you already use.
Sleep medicine billing gets studies, readings and follow-up visits paid, and keeps patients’ PAP coverage intact. Studies are coded by type and split between the lab and the reader, the documentation suppliers need for PAP coverage is in the chart on time, and patient balances are billed only after the plans have paid.

A sleep practice’s documentation decides whether a patient’s therapy is paid, even when someone else bills the device. Medicare covers PAP for an initial 12 weeks, and continued coverage depends on a follow-up visit in a set window and objective proof the patient is using the machine. Meanwhile the studies themselves are billed by type, device and site, often split between a lab and the physician who reads them.
The study type and the follow-up note decide the claim. That is why we check the study codes, the components and the timing of every follow-up visit before claims go out.
Sleep practices bill studies, interpretations and visits, and support device claims billed by suppliers. Each step has its own rules. Here are the failure points, and our fix for each.

What we do
Medicare covers a PAP device for obstructive sleep apnea for an initial 12-week period. To start, the patient needs a face-to-face evaluation and a covered sleep test showing the required number of breathing events per hour. To keep coverage after the first 12 weeks, the treating practitioner must see the patient again no sooner than the 31st day and no later than the 91st day after therapy starts, and document that symptoms have improved.
The note also needs objective adherence: use of the device for at least four hours a night on 70% of nights during a consecutive 30-day period in the first three months. If the patient misses that window, the supplier cannot simply continue. The device is billed by the supplier, but the coverage rests on the sleep practice’s notes.
What we do: when PAP therapy starts, we note the start date and the follow-up window, check that the visit is scheduled inside it, and confirm the follow-up note records the usage data and symptom change suppliers and payers look for.
Sleep claims depend on the study type, the device and who owns the equipment. These are the codes we see most, with what payers check on each.
| Code | What it covers | What payers look for |
|---|---|---|
| 99202 to 99215 | Office visits (E/M) | The level matches the decision making or time documented; modifier 25 with a same-day procedure only when the visit is separate. |
| 9581095811 | In-lab polysomnography, without and with PAP titration | 26 and TC when split; authorization from many plans. |
| 95806G0399 | Home sleep apnea tests | The code that matches the device; many plans require a home test first. |
| 9580095801G0398G0400 | Other home sleep test types | Coded by the channels the device records. |
| 95805 | Multiple sleep latency or maintenance of wakefulness test | The indication documented. |
| 94660 | CPAP initiation and management | Billed only when separate from the visit that day. |
| E0601E0470 | CPAP and bilevel devices | Billed by the supplier; coverage rests on the practice's notes. |
| E0486 | Custom oral appliance for sleep apnea | Billed by an enrolled supplier to the DME contractor or plan. |

It is not for every practice. If you are a hospital-employed group whose billing the hospital handles, you do not need us. And if your in-house team keeps denials low and receivables current, keep them, and consider a periodic billing audit instead.
We look at your clean-claim rate, your denials by payer and reason, sleep study coding and components, PAP follow-up timing, authorizations, and your aging receivables, and tell you what we find, whether or not you go further with us.
We get access to your practice management system and clearinghouse, load each payer's authorization and bundling rules and your fee schedules, list each lab you read for and patients starting PAP therapy, and agree how escalations work. Most practices are live within one to two weeks.
Studies, readings and visits are coded and claims submitted within 24 hours. Rejections are corrected the same day, remittances posted as they arrive, study types, components and follow-up windows checked, and denials worked to their cause, all inside your system.
A report you can read in ten minutes: what was billed and collected by payer, site and service line, what was denied and why, authorizations pending, and what is aging.
You do not change systems to work with Summit Billing Solutions. We work in the practice management and EHR systems below, and through the clearinghouse you already use. If your EHR is not shown, ask; the list grows as we onboard practices.

Sleep practices earn from studies, readings and follow-up visits, and a missed follow-up can cost the patient their therapy coverage. A fee based on collections keeps us working on the whole path, not just the first claim.
Summit Billing Solutions charges between 3% and 9% of monthly collections. Your rate depends on study volume, how many labs you read for, the share of home versus in-lab testing and the state of the receivables, which we see in the free account review.
