CPT 98013: Audio-Only E/M Visit for Established Patients, Low MDM

CPT code 98013 represents an established patient evaluation and management visit provided using synchronous audio-only technology. The code captures encounters with more than 10 minutes of medical discussion, low medical decision making, or at least 20 minutes of total clinician time on a single date. As audio-only telehealth remains an important access modality, this code reflects national attention to remote care options for patients without video capability.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code denotes, how major payers treat audio-only visits, and the practical clinical context for using the code. The publication covers benchmarks where available, recent policy updates affecting audio-only telehealth billing, and considerations for documentation and coding consistency.

This summary provides clinicians, billing staff, and policy analysts with a clear, national-level reference for CPT code 98013, clarifying the service definition, typical settings of care, and the topics addressed in the full publication.

Clinical & Coding Specifications

Clinical Context

A patient with a previously established primary care relationship calls their clinician’s office complaining of worsening cough and low-grade fever. The clinician triages the request and schedules a synchronous audio-only telephone visit because the patient lacks reliable video access. The clinician conducts a focused evaluation lasting more than 10 minutes of medical discussion, documents subjective history, reviews recent medications and allergies, assesses symptoms, and provides management advice including symptomatic treatment and return precautions. The encounter involves low medical decision making (e.g., assessment and adjustment of current therapy, reinforcement of self-care) and the clinician documents a total encounter time of 20 minutes spent on the date of service, including telephone assessment, review of records, and coordination of care. Typical workflow steps: intake and verification of identity and consent, focused history and symptom review, clinical assessment and counseling, documentation of time and medical decision making, and billing under 98013 with any required payer-specific modifier (for example 95 or telehealth-specific payor modifiers) and appropriate diagnosis code(s) representing the acute respiratory condition.

Coding Specifications

Modifier	Description	When to Use
`95`	Synchronous telemedicine service rendered via real-time interactive audio and video	Use if payer requires the `95` modifier for telehealth visits when audio-only is accepted by the payer
`93`	Synchronous telemedicine, audio-only	Use when the service was delivered via audio-only synchronous telecommunication
`GT`	Via interactive audio and video telecommunication systems	Use when payer recognizes `GT` for telehealth encounters
`25`	Significant, separately identifiable E/M service by the same physician on the same day	Use when an in-person service is performed the same day in addition to the audio-only visit and is distinct
`24`	Unrelated E/M service by the same physician during a postoperative period	Use when the audio-only visit addresses issues unrelated to a recent surgery during global period
`52`	Reduced services	Use when the service was partially reduced or not performed as fully described
`22`	Increased procedural services	Use when the audio-only encounter required substantially greater effort than typical and documentation supports increased work
`59`	Distinct procedural service (Note: not in provided list)	Data not available in the input.
`93`	(duplicate avoided)	Data not available in the input.
`00`	No modifier indicated / Placeholder	Rarely reported; used by some internal billing systems when no modifier applies
