can you tell me why some insurance companies are not acknowledging the 93 audio only telehealth modifier
The coding is incorrect for an audio only telehealth visit. Modifier -93 should not be used for these services. Based on the amount of time spent with the patient, one of the following E&M codes should be billed to WellCare:
99441: Telephone evaluation and management service by a physician or other qualified health care professional who may report evaluation and management services provided to an established patient, parent, or guardian not originating from a related E/M service provided within the previous 7 days nor leading to an E/M service or procedure within the next 24 hours or soonest available appointment.
99442: 11-20 minutes of medical discussion
99443: 21-30 minutes of medical discussion
Established patient E&M codes should only be used with commercial insurance payers, depending on their reimbursement guidelines for telemedicine services.
