warning

Do not take impressions or deliver the appliance until you have (1) a valid MD order and (2) prior authorization in hand.

Phase 1 — Before Treatment: Verify & Authorize​

1. Collect the three required documents​

Before scheduling the patient for an appliance, confirm you have all three in the chart:

  1. Sleep study report (PSG or HST type II/III/IV-A with AHI + oximetry)
  2. Physician's written order/Rx for an oral appliance
  3. Copy of the patient's medical insurance card

2. Verify the MD order is complete​

A prescription-pad scribble is not sufficient. The order must state:

  • The OSA diagnosis
  • Why an oral appliance (i.e., why not CPAP)

The order must come from the MD — a dentist cannot write this order.

Stop

If no valid MD order is in hand, do not take impressions and do not deliver. The claim will be denied without it.

3. Check the AHI against payer requirements​

AHI BandWhat's Required
AHI ≥ 15Good to go
AHI 5–14Must have a documented comorbidity: hypertension (>140/90), stroke, ischemic heart disease, daytime sleepiness (Epworth >10), insomnia, or mood/cognition problems
AHI ≥ 30Must also have documented CPAP failure or intolerance

If CPAP intolerance applies, collect:

  • Signed CPAP Intolerance Affidavit
  • Supporting MD note explaining intolerance/contraindication
Stop

AHI 5–14 with no documented comorbidity, or AHI ≥ 30 with no CPAP failure note = denial. Get the documentation first.

4. Get prior authorization​

Submit the PA package — LMN + sleep study + MD order + CPAP affidavit + chart notes — before the lab fabricates anything.

Phase 2 — At the Visit: Document​

5. Complete the screening forms​

Place in the chart:

  • Epworth Sleepiness Scale
  • STOP-BANG questionnaire

6. Perform and document the dental suitability exam​

The doctor's note must confirm:

  • Sufficient teeth to retain the appliance
  • Acceptable periodontal status
  • Healthy TMJ

7. Record the appliance details​

Document:

  • Lab name
  • Appliance brand and model (must be custom-fabricated and FDA-cleared — no boil-and-bite)
  • Lab fee

Phase 3 — Build the Claim​

info

Do not build the claim until the appliance is delivered. E0486 is billed on the delivery date, not the order date.

8. Diagnosis order on the claim​

Medical diagnosis first. The order on the CMS-1500:

  1. G47.33 (OSA) — primary and sole dx on the appliance line
  2. K-codes are never listed first
  3. Cause codes (W/V) go last if applicable

9. Bill the appliance line​

  • Code: E0486 + modifier NU (new equipment)
  • Date of service: delivery date
  • Place of service: 12 (home)

10. Fill the key boxes on the CMS-1500​

Box 17Ordering MD name + NPI
Box 17bMD NPI
Box 23Prior authorization number
Box 20Lab fee (if applicable)
Box 32Lab name and address
Date of serviceAppliance delivery date

11. Get the Proof of Delivery signed​

The signed POD must contain:

  • Patient signature
  • Delivery date
  • Device description
  • Statement that instructions were given
Stop

Do not submit without a signed Proof of Delivery in the chart. An audit without a POD results in payment clawback.

12. Hold the dental claim​

Wait for the medical EOB before submitting the dental claim. Then send dental as secondary with the medical EOB attached.

Phase 4 — Submit & Follow Up​

  • Do not bill adjustment visits for the first 90 days after delivery — adjustments are included in E0486.
  • Once the appliance reaches maximum advancement, arrange a titration sleep study with the MD to confirm efficacy.
  • Replacements are covered roughly every 3–5 years with documentation of wear or failure.
  • If the claim is unpaid at 3 weeks, call the payer using the reference number from your verification call.
  • Denied as "not medically necessary"? Appeal it — ~70% of letter appeals succeed. Resubmit with a stronger LMN that quotes the payer's own coverage policy.
  • File all call logs, auths, EOBs, and appeals in the chart. Retain for 7 years.
