Coding, claims, prior authorization and denial recovery for sleep labs, hospital sleep programs, sleep medicine practices and PAP supply lines.
Sleep medicine billing loses money on details a general biller rarely checks: a split-night study billed as two tests, a 5-hour recording sent without modifier 52, or a CPAP patient with no adherence data in the chart by day 91. Each one turns a paid claim into a denial or a recoupment. Luxen runs full-service medical billing for sleep labs and sleep practices inside your current systems, with certified coders and a BAA signed first.

Sleep study billing services cover coding, claim submission, prior authorization, denial work and AR follow-up for sleep labs and sleep medicine practices, from in-lab polysomnography to home sleep tests and PAP supplies. Medicare pays $674.36 nationally in 2026 for a globally billed CPT 95810, and a split-night study bills as 95811 alone.
One sleep patient can generate a visit, a test, an interpretation and an equipment claim in the same month. We bill for:
Service lines: attended and pediatric polysomnography, titration, MSLT and MWT, actigraphy, follow-up visits, PAP devices and supplies.
The top three denial reasons accounted for 58% of denied dollars in the average practice we review (Luxen billing reviews), and in sleep medicine they cluster in these rows. Dollar figures are 2026 Medicare national payments.
| Scenario | Codes | What goes wrong | $ at stake per claim | Luxen audit finding |
|---|---|---|---|---|
| Split-night study | 95810 + 95811 | Both billed, when 95811 alone covers a split night | $674.36 (95810) denied or recouped | 95810 was billed alongside 95811 on 5% of split-night studies (Luxen claim audit) |
| Short recording | 95810-52 | Under 6 hours of recording billed as a full study | $674.36 exposed on audit | Recordings under 6 hours went out without modifier 52 on 8% of in-lab sleep studies (Luxen claim audit) |
| Hospital outpatient study | 95810-26 | Physician bills globally when the hospital owns the technical service | $554.79 recouped | Coding and modifier errors caused 21% of denials (Luxen claim audit) |
| In-lab study, plan expects a home test | 95810 vs 95806 | No authorization or no documented reason a home test was unsuitable | $674.36 vs $103.21 | In-lab studies with no documented reason to skip a home test caused 14% of sleep study denials (Luxen claim audit) |
| CPAP patient past day 91 | E0601-KX, A7030 | Adherence and re-evaluation missing | Repeat facility study, $674.36 | Missing adherence or refill documentation caused 26% of PAP supply denials (Luxen claim audit) |
Sleep codes turn on three questions: was a technologist present, how many parameters were recorded, and how old is the patient. Our medical coding team checks each against the study report.
| Code | What it covers | Global | 26 | TC |
|---|---|---|---|---|
| 95810 | Attended PSG, age 6 or older, staging plus 4 or more parameters | $674.36 | $119.58 | $554.79 |
| 95811 | 95810 with CPAP or bilevel initiation, including split night | $708.43 | $123.92 | $584.52 |
| 95808 | Attended PSG, any age, staging plus 1 to 3 parameters | $512.70 | $81.50 | $431.21 |
| 95782 | Attended PSG, younger than 6, 4 or more parameters | $1,010.38 | $120.91 | $889.47 |
| 95783 | 95782 with CPAP or bilevel initiation | $1,070.16 | $131.27 | $938.90 |
| 95807 | Attended study of ventilation, effort, heart rate and oxygen saturation | $443.90 | $59.45 | $384.44 |
| 95805 | MSLT or maintenance of wakefulness testing | $479.97 | $57.78 | $422.19 |
| 95806 | Unattended: heart rate, oxygen saturation, airflow and effort | $103.21 | $44.76 | $58.45 |
| 95800 | Unattended: heart rate, oxygen saturation, respiratory analysis, sleep time | $141.29 | $38.75 | $102.54 |
2026 national payments at the $33.4009 conversion factor, before locality adjustment.
G0398, G0399 and G0400 describe Type II, III and IV portable monitors with at least 7, 4 and 3 channels. Medicare contractor guidance says unattended studies should be billed with the code that most accurately describes the service, so the device report picks the code.
| Setting | Technical service | Interpretation |
|---|---|---|
| Physician-owned lab or office | Practice bills globally, or TC when an outside physician reads | Outside reader bills 26 |
| Hospital outpatient lab | Hospital, on its institutional claim | Physician bills 26 only |
| Home test dispensed by the practice | Practice that owns the device | Global if the practice reads, 26 if a separate physician reads |
Part B pays only the hospital for hospital outpatient services, with physician services excepted, so a globally billed hospital study is overpaid by the $554.79 technical amount.
Aetna’s clinical policy covers attended in-lab polysomnography for adults with conditions such as moderate to severe pulmonary disease, neuromuscular disease, congestive heart failure (NYHA class III or IV), chronic opioid use or a BMI above 45, or after a negative or technically inadequate home test. Our eligibility and prior authorization team matches the ordered study to plan criteria before the night is booked.
The First Coast polysomnography LCD for Florida, Puerto Rico and the Virgin Islands requires the interpreting physician to hold sleep medicine board certification or serve on the active staff of a facility accredited by AASM, ACHC or the Joint Commission, and lists technologist credentials such as RPSGT. It also says an MSLT is valid only after polysomnography the preceding night. For medical billing in Florida, accreditation records belong in the claim file, and our credentialing team tracks them.
Medicare covers an initial 12-week CPAP trial when the sleep test shows an AHI or RDI of 15 or more, or 5 to 14 with documented excessive daytime sleepiness, impaired cognition, mood disorders, insomnia, hypertension, ischemic heart disease or history of stroke. The patient needs an in-person evaluation before the sleep test. Bilevel E0470 requires a documented E0601 trial that proved ineffective.
| Supply codes | Usual maximum |
|---|---|
| A7027, A7030 full face mask, A7034 nasal mask, A7037 tubing | 1 per 3 months |
| A7028, A7029, A7031, A7032, A7033, A7038 | 2 per month |
| A7035, A7036, A7039, A7046 | 1 per 6 months |
Our denials and AR recovery team works resupply denials by the missing element: order, adherence record or re-evaluation note.
Custom oral appliance E0486 must be provided and billed by a licensed dentist after a treating practitioner orders it from a qualifying sleep test. Above an AHI or RDI of 30, the record must show PAP intolerance or a contraindication. Prefabricated E0485 is denied as not reasonable and necessary.
The rule: 95811 alone is billed for split-night studies because it includes 95810. The cost: the extra line is a $674.36 denial or a later recoupment. Luxen audit: 95810 was billed alongside 95811 on 5% of split-night studies (Luxen claim audit).
The rule: Part B pays only the hospital for hospital outpatient services, except physician services (42 CFR 410.42), so the physician bills 95810-26 at $119.58. The cost: $554.79 of overpayment that comes back on audit. Luxen audit: Coding and modifier errors caused 21% of denials (Luxen claim audit).
The rule: adherence is 4 or more hours on 70% of nights in a consecutive 30-day period within the first 3 months, with re-evaluation between day 31 and day 91. The cost: a patient who misses it needs a repeat facility study, such as 95810 at $674.36, before coverage restarts. Luxen audit: Missing adherence or refill documentation caused 26% of PAP supply denials (Luxen claim audit).
The rule: the First Coast polysomnography LCD says more than one home test to diagnose OSA would not be expected without persuasive evidence of medical necessity. The cost: a denied $103.21 repeat 95806 and a delayed in-lab study. Luxen audit: In-lab studies with no documented reason to skip a home test caused 14% of sleep study denials (Luxen claim audit).
We run the revenue cycle from eligibility to zero balance inside the practice management system you already use. How full-service billing works.
Certified coders review charges against your documentation and payer rules before the claim goes out, so the denial is prevented rather than appealed. Medical coding.
Aged and denied claims are worked to resolution, then the upstream cause is fixed so the same claims stop coming back. Denials and AR recovery.
Benefits are verified and authorizations secured before the appointment, which is the cheapest place in the cycle to stop a denial. Eligibility and prior authorization.
Statements, balance questions and payment plans are handled by the same team that worked the claim. Patient billing.
Payer enrollment and re-credentialing are tracked through to approval, so a lapsed credential never quietly stops payment. Credentialing.
A HIPAA-trained front-office assistant working inside your EHR on calls, scheduling, intake and referrals, alongside the billing team. Medical virtual assistant.
Charges get lost in the hand-offs between sleep systems. We work inside the tools you already use, with no migration:
Each week we match completed studies in the scoring platform to signed interpretations in the EHR.

combined billing and coding experience
Completed sleep studies were not consistently matched to the physician’s final interpretation and claim. Luxen reconciled the study platform against our EHR, found 164 unbilled tests, and recovered $44,700.
Practice Administrator, independent sleep medicine center
Recurring CPAP supply claims were delayed whenever proof of delivery or updated documentation was missing. Luxen introduced a renewal tracker, increased first-pass acceptance from 78% to 94%, and added $18,200 in monthly collections.
Operations Director, sleep medicine and equipment practice
Full engagements are written up in our dental practice case study and our ambulance billing case study.
Sleep programs run on two clocks: recording night to claim, and the day-91 PAP adherence deadline. Track both next to standard AR measures.
| KPI | Luxen benchmark | What to act on |
|---|---|---|
| First-pass denial rate | Across 38 client practices, first-pass denial rate fell from 14.2% to 6.1% within 90 days of onboarding (Luxen client data) | Split-night and modifier 52 edits |
| Recording night to claim | Sleep studies were billed a median 12 days after the recording night (Luxen billing reviews) | Unsigned interpretations |
| AR past 90 days | 27% of total AR sat past 90 days in the average practice reviewed (Luxen billing reviews) | Aged in-lab studies first |
| Denials never worked | 19% of denied claims were never reworked or appealed (Luxen billing reviews) | An owner and deadline per denial |
| Appeal success | Appeals filed by Luxen were overturned 68% of the time (Luxen client data) | Attach the policy criteria |
Practices that reviewed AR ageing monthly carried 12 fewer days in AR (Luxen billing reviews).
3% to 6% of collections
Luxen's pricing generally falls between 3% and 6% of collections, depending on claim volume, specialty, payer mix, and how much of the revenue cycle your practice hands over.
Higher-volume practices usually land toward the lower end. Smaller or more complex practices land higher because there is more work per account. There is no setup fee and no exit fee, and the agreement runs month to month with 30 days notice.
A lower fee attached to weak billing is still expensive. The number that matters is what your collections do after you hire someone.
Luxen charges 3% to 6% of collections, month to month, no setup or exit fee. Example: a sleep practice collecting $150,000 a month.
| Service line | Monthly collections | Luxen at 3% | Luxen at 6% | In-house at 7.9% |
|---|---|---|---|---|
| Office visits and follow-ups | $45,000 | $1,350 | $2,700 | $3,555 |
| In-lab studies | $60,000 | $1,800 | $3,600 | $4,740 |
| Home sleep tests | $15,000 | $450 | $900 | $1,185 |
| PAP devices and supplies | $30,000 | $900 | $1,800 | $2,370 |
| Total | $150,000 | $4,500 | $9,000 | $11,850 |
Fully loaded in-house billing cost 7.9% of collections for practices under $2M, across 96 practices that shared payroll data (Luxen billing reviews), or $11,850 a month here. Your rate within the range depends on claim volume and PAP resupply work. In-house teams also carry vacancy risk: open biller roles took a median 67 days to fill (Luxen Practice Manager Survey 2026).
| Partner type | Sleep coding depth | PAP supply billing | Works in your systems | Cost basis |
|---|---|---|---|---|
| In-house team | One or two billers | Often sent to a DME vendor | Yes | Salaries and software |
| Generalist billing company | Rarely sleep-specific | Often excluded | Sometimes | Percent of collections |
| Specialty sleep billing company | Strong on studies | Varies | May require its platform | Percent or per claim |
| EHR vendor RCM | Vendor templates | Rarely | Only that EHR | Percent plus software |
| Luxen | Certified coders for studies and titration | Yes, including KX | Yes, no migration | 3% to 6% of collections |
Use the same questions to compare medical billing companies.
A 30-minute look at your AR ageing, denial reasons and payer mix. You leave knowing what is recoverable, what we would work first and what it would cost.
We sign a business associate agreement before anyone touches your system. Your named team then works inside the practice management system and clearinghouse you already use. Nothing is migrated, and claims are being worked within two weeks of the signed BAA.
Aged and denied claims come first because that is revenue you have already earned. Most practices see the first recovered payments inside three weeks.
Once the backlog is moving, we take over the agreed part of the daily cycle: eligibility, coding review, submission, posting, denials and patient balances.
You know who owns your claims. The team works inside the practice management system and EHR you already run, with no migration.
Claims are coded by certified coders against your documentation and payer rules. Automation handles the repetitive checks so people spend their time on the claims that need judgment.
We sign a business associate agreement before accessing protected health information, and access is limited to the named people on your account.
We look at your AR ageing, volume, payer mix and denial profile first, then tell you what we believe is recoverable and what it would cost.
A billing company is a poor fit if you are not willing to share visibility into your billing, if the vendor uses a rotating pool of people who never learn your practice, or if it cannot explain why your claims are being denied. Be wary of anyone promising large collection increases before they have seen your AR ageing. The right partner makes your revenue cycle more visible, not less.
In-lab polysomnography for patients 6 and older bills as 95810, or 95811 when CPAP or bilevel therapy starts, including split-night studies. Patients younger than 6 use 95782 or 95783, and MSLT or MWT uses 95805. Home tests use CPT 95800, 95801 or 95806, or HCPCS G0398 to G0400.
Luxen charges 3% to 6% of collections, so a practice collecting $150,000 a month pays $4,500 to $9,000. Fully loaded in-house billing cost 7.9% of collections for practices under $2M in our billing reviews. There is no setup fee and the agreement is month to month.
Median time from signed BAA to first claims worked was 9 business days, and most practices have working claims in about 2 weeks. We start with the oldest open in-lab studies because they carry the most dollars. Your team keeps the same EHR and scoring software.
Yes. We work inside your EHR and practice management system and pull completed studies from platforms such as Sleepware G3, Profusion or Noxturnal. Each week we match recorded studies to signed interpretations. No data migration is needed.
Bill 95811 alone, because it includes the diagnostic portion described by 95810. If recording runs under 6 hours, add modifier 52. Aetna policy supports a split-night study when the AHI is greater than 15 in the first 2 hours.
Thirty minutes, no deck and no fee. We look at what is sitting past 90 days and where your denials cluster, and you leave knowing what is recoverable, what we would work first, and what it would cost.
