Summary & Overview
CPT 0964T: Single-Arch Oral Prosthesis for Obstructive Sleep Apnea
CPT code 0964T covers the creation and fitting of a single-arch custom oral prosthesis intended to expand the jaw and improve airway patency for patients with obstructive sleep apnea. Nationally, this code matters because it defines coverage pathways and documentation requirements for a non-advancing, single-arch oral appliance distinct from mandibular advancement devices. It has implications for dental and sleep medicine providers, durable medical equipment workflows, and payers managing OSA treatment options.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service setting, common billing modifiers, and what typical coverage discussions center on for this type of device. The report summarizes available benchmarks where provided, notes areas where input data were not available, and outlines policy-relevant considerations for coding, medical necessity documentation, and site-of-service billing. Clinical readers will gain clarity on how 0964T differs from mandibular advancement appliances; billing professionals will find guidance on documentation focus points used by major payers; and policy readers will see the national relevance of specifying device mechanics (single-arch, non-advancing) in coding and coverage determinations.
Billing Code Overview
CPT code 0964T describes a clinical service in which the provider takes impressions of the patient’s oral structures and creates a custom prosthesis designed to expand the jaw and improve airflow to address obstructive sleep apnea. The device is fabricated to fit a single arch — placed on either the upper or lower jaw — and does not include a mechanism to advance the mandible.
Service type: Custom oral prosthesis fabrication and fitting for obstructive sleep apnea.
Typical site of service: Dental office or ambulatory surgical/dental clinic where oral prostheses are custom-fit and delivered.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult diagnosed with obstructive sleep apnea (OSA) who cannot tolerate continuous positive airway pressure (CPAP) therapy or prefers an oral appliance. The patient presents to a dental sleep medicine or maxillofacial prosthetics clinic after referral from a sleep medicine physician following polysomnography demonstrating mild to moderate OSA. The provider performs an oral examination, reviews sleep study results and dental/oral health status, obtains informed consent, and takes dental impressions or digital scans of the maxillary or mandibular arch. A custom single-arch mandibular or maxillary prosthesis is fabricated to expand the dental arch and increase airway patency; this device does not include a titratable mechanism to advance the mandible. At a follow-up visit the device is fitted, adjusted for comfort and retention, and the patient is instructed on wear schedule and follow-up sleep or symptomatic assessment. Typical sites of service include outpatient dental offices, dental sleep medicine clinics, or ambulatory surgery centers when concurrent procedures are performed.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required to produce the appliance is substantially greater than typical and documentation supports increased complexity. |
51 | Multiple procedures | Use when this procedure is billed in the same session with other unrelated procedures and payer requires a multiple-procedure modifier. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned; document reason and extent. |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances; document why discontinued. |
59 | Distinct procedural service | Use when a separate, distinct service is performed on the same day that is not normally reported together (apply per payer rules). |
76 | Repeat procedure by same physician | Use when the same procedure must be repeated by the same provider for a separate encounter on the same day. |
77 | Repeat procedure by another physician | Use when the same procedure is repeated by a different provider on the same day. |
KT | Acute care split-shared services (example) | Use per payer guidance where applicable for split/shared professional services in facility settings. |
RT | Right side (example) | Use when laterality modifiers are required by payer policy (rare for single-arch appliances). |
| Taxonomy Code | Specialty | Notes |

| 122300000X | Dentist | General dentists experienced in dental appliance fabrication for sleep apnea. |
| 1223D0002X | Orofacial Pain/Trauma | Specialists in oral appliance management for sleep-disordered breathing. |
| 1223P0106X | Prosthodontist | Fabrication and fitting of custom oral prostheses and dental appliances. |

R06.83 | Snoring | Symptom often associated with OSA; may prompt evaluation leading to appliance therapy. |
Z72.0 | Tobacco use | Risk factor that may contribute to OSA severity and influence treatment planning. |

|---|---|---|
0964T | The provider takes impressions of the patient’s oral structures and creates a custom prosthesis designed to expand the jaw and improve airflow to address obstructive sleep apnea. The prosthesis is fitted to a single arch, meaning it is placed on either the upper or lower jaw, without a mechanism to move the lower jaw forward. | Primary code for single-arch, non-titratable oral airway-expanding prosthesis fabrication and fitting. |
21010 | Reconstruction of mandibular alveolar ridge, with tissue graft; first stage. | May be performed in patients requiring ridge augmentation prior to prosthesis fit or when alveolar anatomy prevents proper device retention. |
70365 | Dental radiographic imaging, panoramic; film/sensor | Commonly obtained to evaluate dentition, arch form, and prosthesis fit prior to fabrication. |
94640 | Pressurized inhalation treatment for acute airway obstruction (example airway code) | Occasionally used in acute respiratory management but not typically part of appliance workflow; included as a related code for airway-focused clinical contexts. |
99070 | Supplies and materials (medical) | Used to report consumable materials not included in the procedure when payer policy allows separate reporting. |
