Chatbot Demonstrates Moderate Interrater Reliability in Billing for Hand Surgery Clinic Encounters
View abstract on PubMed
Summary
This summary is machine-generated.Artificial intelligence (AI) chatbots show moderate reliability in medical billing, achieving 68% agreement with a surgeon. This suggests AI could streamline administrative tasks in healthcare, improving efficiency and reducing costs.
Area Of Science
- Medical Informatics
- Artificial Intelligence in Healthcare
- Healthcare Administration
Background
- Artificial intelligence (AI) presents opportunities to alleviate administrative burdens in healthcare.
- Machine learning applications in medical coding and billing may offer significant time and cost savings with minimal risk to patient outcomes.
Purpose Of The Study
- To evaluate the performance of a publicly available AI chatbot, Gemini, in generating Current Procedural Terminology (CPT) codes for surgical encounters.
- To assess the interrater reliability between the AI chatbot and a hand surgeon for medical billing accuracy.
Main Methods
- A large language model chatbot (Gemini) was queried with 139 de-identified patient encounters.
- The AI was asked to assign CPT codes based on encounter type criteria.
- Percent agreement and Cohen's kappa coefficient were calculated to measure reliability.
Main Results
- Gemini achieved 68% overall agreement with the surgeon, with a kappa coefficient of 0.586 (moderate reliability).
- Highest agreement was observed for postoperative encounters (98%), while new encounters showed the lowest agreement (48%).
- The AI suggested higher billing levels 31 times and lower levels 10 times, with 4 incorrect encounter type codes.
Conclusions
- A general-purpose AI chatbot demonstrated moderate interrater reliability in medical billing tasks when compared to a hand surgeon.
- Integrating AI tools into physician workflows could enhance billing accuracy and speed, potentially lowering administrative expenses.

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
Standardized methods of communication have been developed to ensure that information is...
