Summary & Overview
CPT 70130: Mastoid X‑Ray Series for Mastoiditis and Vestibular Evaluation
CPT code 70130 represents a plain-film mastoid radiographic series with at least three views per side, used to evaluate suspected mastoiditis, vestibular disorders, or palpable head and neck masses. Nationally, this imaging code is a targeted diagnostic tool in otolaryngology and emergency medicine workflows where rapid assessment of mastoid air cell disease or structural abnormalities influences subsequent management.
Key payers in coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and reimbursement policies for 70130 affect imaging utilization, site-of-care decisions, and billing practices across hospital radiology departments, freestanding imaging centers, and outpatient surgical settings.
Readers will find a concise briefing on clinical context and typical use cases for this radiographic series, followed by benchmarking and payer coverage summaries where available. The publication covers common billing modifiers and coding considerations, outlines typical sites of service, and identifies areas where policy updates or payer-specific documentation requirements commonly influence claim adjudication. Data not available in the input are clearly noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to the outpatient radiology department with persistent ear pain, fever, and worsening postauricular swelling after several days of acute otitis media. The referring otolaryngologist documents concern for mastoiditis and requests radiographic evaluation. The clinical workflow: patient registration and verification of insurance (typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, Medicare); review of clinical indication and prior imaging; screening for pregnancy status if applicable; positioning the patient in the radiology suite; acquisition of a minimum of three plain radiographic views of the mastoid cavity per side (70130) to assess opacification, air cell coalescence, or bony destruction; image interpretation by a radiologist with a signed report; communication of urgent findings to the referring otolaryngologist; image storage to PACS and billing submission using 70130 with any appropriate modifiers. Typical sites of service include hospital radiology departments, outpatient imaging centers, and emergency departments. The typical patient scenario also includes evaluation of vertiginous syndromes, vestibular complaints, or palpable head/neck masses when mastoid or temporal bone radiography is indicated.
