Headline: CPT code 70300: Single Dental Radiograph Used to Evaluate a Tooth and Surrounding Tissue
Lead: CPT code 70300 denotes a single dental radiograph (X-ray) performed to detect abnormalities in a tooth and its surrounding tissues. The code captures a common, focused diagnostic imaging service used in dental and oral healthcare settings.
CPT code 70300 represents a brief, single-image diagnostic X-ray centered on one tooth or a localized area. Nationally, dental radiographs are an essential diagnostic tool that influence treatment planning, including restorative, endodontic, and surgical interventions. Given their high frequency in outpatient dental practices, accurate coding of this service affects clinical documentation, billing accuracy, and utilization monitoring.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of benchmarks and coverage considerations across major commercial and public payers, a summary of typical sites of service and clinical context for use, and notes on common billing modifiers where applicable. The publication also outlines what to expect in billing workflows for a single dental radiograph and highlights areas where policy or coding guidance commonly affects reimbursement and claim adjudication.

Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient dental clinic with localized tooth pain and suspected periapical pathology after recent trauma. The dentist obtains a focused single intraoral radiograph to evaluate a specific tooth and surrounding alveolar bone. The workflow: check-in and medical history review; targeted oral examination identifying the symptomatic tooth; positioning of the patient and intraoral sensor/film; acquisition of a single periapical or bitewing radiograph under the supervision of the dental provider; image review by the dentist for caries, root fracture, periapical radiolucency, or foreign body; documentation of indication, images obtained, findings, and interpretation in the dental record; decision for treatment such as restoration, root canal therapy, extraction, or additional imaging if needed. Typical site of service is an outpatient dental office or oral surgery clinic. Service type is a single diagnostic dental radiograph (intraoral X-ray). Typical patient scenario: adult with focal toothache after biting hard food, suspected cracked tooth or deep caries requiring a periapical radiograph to assess root integrity and periapical status.
