Summary & Overview
HCPCS K1027: Custom Oral Appliance for Upper Airway Collapse, Includes Fitting
HCPCS Level II code K1027 identifies a custom-fabricated oral appliance designed to reduce upper airway collapsibility, delivered without a fixed mechanical hinge and including fitting and adjustment. Nationally, this code is relevant to payers and clinicians involved in management of sleep-disordered breathing where oral devices are an alternative to continuous positive airway pressure (CPAP) or surgical approaches. Adoption affects durable medical equipment benefit design, coverage determinations, and behavioral health and sleep medicine care pathways.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for oral appliance therapy, payer coverage patterns and benchmarks where available, coding nuances tied to device fabrication and fitting, and considerations for authorization and claim submission. The publication summarizes policy variations among major national payers and highlights areas where coding clarity can impact reimbursement and care coordination.
This summary equips clinicians, billing teams, and policy analysts with the foundational information needed to interpret use of K1027, understand typical places of service, and anticipate documentation and billing workflows associated with custom oral appliance therapy.
Billing Code Overview
HCPCS Level II code K1027 describes an oral device/appliance used to reduce upper airway collapsibility, custom fabricated, without a fixed mechanical hinge, and includes fitting and adjustment. This device is intended to manage upper airway patency by repositioning or stabilizing oral structures during sleep or related conditions.

Typical site of service: Dental office, dental specialty clinic, or outpatient sleep medicine setting
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with symptoms of excessive daytime sleepiness, loud snoring, and witnessed apneas is diagnosed with mild-to-moderate obstructive sleep apnea (OSA) after a sleep study. The patient is not a candidate for continuous positive airway pressure (CPAP) therapy due to intolerance. An oral appliance designed to reduce upper airway collapsibility without a fixed mechanical hinge is custom-fabricated to advance or stabilize the mandible during sleep. The workflow includes an initial dental sleep medicine or otolaryngology consultation, intraoral examination, dental impressions or digital scans, fabrication of the custom device by a dental laboratory, a fitting and adjustment visit to ensure fit and comfort, and follow-up sleep symptom assessment and possible repeat titration or adjustment. Typical clinicians involved are dental sleep medicine specialists, dentists with a dental sleep medicine or prosthodontic focus, and sleep medicine physicians. Typical site of service is an outpatient dental clinic, dental specialty office, or ambulatory clinic where oral appliances are fitted and adjusted. Payors commonly encountered in authorization and billing processes include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
