Summary & Overview
CPT 70310: Limited Dental Radiographic Examination
CPT code 70310 represents limited dental radiography—X‑rays of some, but not all, teeth—used to evaluate localized dental issues. Nationally, this code captures a common, focused imaging service frequently ordered for localized pain, suspected localized infection, or to assess specific teeth prior to targeted procedures. Its use affects billing consistency across dental and outpatient sites and contributes to utilization and quality monitoring for imaging practices.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for limited dental radiographs, common billing and coding considerations, and typical sites of service. The publication outlines payer coverage patterns and benchmarks where available, highlights relevant policy or documentation expectations affecting reimbursement, and places the code in clinical workflow context for dental and outpatient clinicians and billing teams.
This summary is intended for national audiences seeking clarity on what CPT code 70310 denotes, which services it covers, and the practical billing and clinical contexts in which limited dental radiographs are used. Data not available in the input where applicable.

Clinical & Coding Specifications
Clinical Context
A patient presents to a dental clinic or oral and maxillofacial radiology suite with localized dental symptoms such as tooth pain, suspected caries, periapical pathology, or periodontal disease affecting a subset of the dentition. The provider performs intraoral radiographic imaging limited to selected teeth (bitewing or periapical images) rather than a full-mouth series. Typical workflow: patient intake and history focused on the symptomatic area; infection control and positioning; acquisition of targeted intraoral images using a dental x-ray unit; immediate image review by the dentist or oral surgeon to evaluate for decay, periapical radiolucency, root morphology, or foreign bodies; documentation of indications, number and type of images, findings, and clinical decision (restorative treatment, endodontic referral, extraction, or monitoring). Typical sites of service include dental offices, oral surgery practices, community dental clinics, and ambulatory oral radiology centers.
