No problem, the code for a custom made oral appliance for snoring and/or sleep apnea is:
Hi Linda

E0486 - Oral device/appliance used to reduce upper airway collapsibility, adjustable or non-adjustable, custom fabricated, includes fitting and adjustment

If the device is not custom made but pre-fabricated, the code is:
E0485 - Oral device/appliance used to reduce upper airway collapsibility, adjustable or non-adjustable, prefabricated, includes fitting and adjustment

The ICD-10 diagnosis code for snoring is:
R06.83

However, just a heads up, most medical insurers do not offer coverage for oral appliances to treat snoring alone, as they consider it "not medically necessary". However, most insurer will cover them with a diagnosis of Obstructive Sleep Apnea (OSA).

Hope this helps!
