Frequently Asked Questions
Efficient internal medicine billing is crucial to providing high-quality medical care to adults. However, internists have their concerns regarding the process. Below we have answered some questions that they frequently ask. Whether you’re practicing internal medicine individually or affiliated with a hospital, these will effectively clear your confusion. Let’s have a look:
1) What types of services are billed under internal medicine?
Commonly billed services include preventive care visits, chronic care management, diagnostics and lab reviews, consultations, and treatment of adult medical conditions — mostly through evaluation and management codes, with add-on codes for services like CCM and annual wellness visits.
2) Can I provide internal medicine services via telemedicine?
Yes — telehealth is a standard part of internal medicine now. Telephone visits bill with 99441-99443 codes, while video visits use the office E/M range 99202-99215 with modifier 95 for commercial payers or place of service 02 for Medicare, plus documented consent and medical necessity.
3) What is the role of medical history and risk assessment in internal medicine billing?
Medical history and risk assessment drive E/M code level selection — the complexity of problems, data reviewed, and risk of complications determine the service level billed. Documenting these elements fully is what makes the chosen code level defensible during audits and downcoding reviews.
