Codes and Classifications

- HCPCS - Healthcare Common Procedure Coding System
- HCUP - Healthcare Costs and Utilization Project
- ICD - International Classification of Disease
- ICF - International Classification of Functioning, Disability, and Health
- Reimbursement Toolkit
CPT -- Current Procedural Terminology
- The American Medical Association produces this annual list to classify and report medical services and procedures.
- Public and private health insurance programs depend on CPT codes to describe medical, surgical, and diagnostic services, to manage reimbursements, and to facilitate reliable nationwide communication among physicians, other healthcare providers, patients, and third parties
How to find them: The AMA no longer has a free site, but you can look on Google (please check more than one source, just to raise the chance that you have the correct code)
HCPCS -- Healthcare Common Procedure Coding System
The HCPCS has two levels:
- the CPT (whose information is on the previous tab)
- the system that identifies "products, supplies, and services not included in the CPT codes, such as ambulance services and durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) when used outside a physician's office."
- --- This system was created to identify services, supplies, and equipment that are not included in the CPT but which *are* covered by Medicare and other insurers.
- Unlike the CPT and ICD, you *cannot* search this with keywords, but only with the DMEPOS code itself
- The easiest way to find those is by searching the open web, but look at more than one source to make sure you've found the correct code
HCUP -- Healthcare Costs and Utilization Project
Agency for Healthcare Research and Quality (AHRQ) -- This agency works to improve the quality, safety, and cost-effectiveness of health care throughout the U.S. It has data on healthcare expenditures; reports about specific populations such as children, women, and minorities; and much more. Here is the Research Tools and Data page.
- The Healthcare Cost and Utilization Project (HCUP) collects the data from "State data organizations, hospital associations, private data organizations, and the Federal government," and "includes the largest collection of longitudinal hospital care data in the United States," beginning in 1988
- The databases within HCUPnet (middle column) help research on health policy issues such as "cost and quality of health services, medical practice patterns, access to health care programs, and outcomes of treatments at the national, State, and local market levels"
- The national statistics are updated annually, and state statistics are updated as new state data are processed
- There is at least an 18-month lag between the end of the calendar year and the availability of the National (Nationwide) Inpatient Sample (NIS)
1. --> Before you go to HCUPnet, get an ICD-9 code
2. Go to the HCUPnet page. Under HCUP Products, choose HCUPnet.
2. You can choose among various databases. Start with "National Statistics on All Stays"
3. Choose "researcher; medical professional"
4. Start with "statistics on specific diagnoses or procedures"
5. Select the latest year (2013) or whatever year you want
6. At the bottom, choose "use ICD code"
ICD - International Classification of Disease
- The ICD is used to code signs, symptoms, injuries, diseases, and conditions
- It standardizes reporting of illness, death, and medical procedures; and the classification of diseases and other health problems recorded on many types of health and vital records, such as death certificates
- This allows the compilation of national mortality and morbidity statistics by WHO Member States, which is also essential for compiling of statistical info about diseases in a format that allows international comparison of those data
- The ICD was originally created by the World Health Organization (WHO), and is now maintained by the Centers for Medicare & Medicaid Services (CMS) and the National Center for Health Statistics (NCHS).
ICF -- International Classification of Functioning, Disability, and Health
This classification was created by the World Health Organization (WHO) and approved in 2001.
Its purpose is to provide a "framework for measuring health and disability at both individual and population levels."
The WHO page about the ICF includes:
(Remember that this framework is only one piece of a complicated landscape!)
