Final answer:
The ICD-9-CM contains diagnosis codes, procedure codes, and V-codes and E-codes.
Step-by-step explanation:
The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) is a system used to classify and code diagnoses and procedures in healthcare. It is primarily used in the United States. In the ICD-9-CM, there are three types of codes:
- Diagnosis codes: These codes describe the patient's condition or disease. They are alphanumeric codes that provide specific information about the diagnosis, such as the location, severity, and cause.
- Procedure codes: These codes describe the medical procedures or interventions performed on the patient. They provide information about the type of procedure, the approach, and any devices or instruments used.
- V-codes and E-codes: V-codes are used to indicate circumstances that may affect patient care, such as a history of a specific disease or the need for an immunization. E-codes are used to classify external causes of injury or poisoning.
These codes are used by healthcare professionals for various purposes, including documentation, reimbursement, research, and statistical analysis.
