CDT D0230: Intraoral Periapical Each Additional Radiographic Image

CDT code D0230 represents an additional intraoral periapical radiographic image used in dental care when more than one periapical film is required for diagnosis or treatment planning. Nationally, periapical imaging is a routine diagnostic tool in general dentistry and specialty services such as endodontics; accurate coding of additional images affects claim adjudication, patient cost sharing, and encounter documentation. Key national payers covered in this review include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will find a concise explanation of the code’s clinical context, how it pairs with the first periapical image code, and common scenarios that prompt additional periapical exposures. The publication outlines payer coverage considerations, common modifiers reported with additional radiographic services, and associated diagnostic ICD-10 codes used to support medical necessity. Related dental imaging codes and service alternatives are identified for coding clarity. If specific service-line metadata or payer-specific fee schedules are needed, note that detailed reimbursement data is not present in the input. This summary is intended to orient clinicians, billing staff, and policy analysts to the clinical purpose and billing context of CDT code D0230 at a national level.
