Medical Coding
The Current Procedural Terminology (CPT) Manual is a listing of descriptive terms and identifying codes for reporting medical, surgical, and diagnostic services. This five digit numeric coding methodology is not only utilized for billing purposes, but provides a uniform language applicable to patient care education, research, and utilization comparisons.
The "International Classification of Diseases, 9th Revision" (ICD-9-CM), is a numeric coding system describing diseases, symptoms, conditions, complications, external causes, as well as drugs and chemicals.
Utilizing the above coding systems, UCLA Health Systems is committed to submitting only compliant billings for professional fees; and further, strives to provide reasonable assurance concerning compliance with conditions of payment and encounter data reporting under managed care plans.
To ensure that all UCLA physicians and health care providers are in compliance with current diagnosis guidelines for coding and reporting, in addition to other important rules and regulations pertaining to coding inquiries, please see the information provided on this site.
