Final answer:
The 10-digit number assigned to providers for identification purposes when submitting services to payers is the National Provider Identifier (NPI). ICD codes would be found on a patient's medical record and on billing statements, documenting diagnoses and treatments.
Step-by-step explanation:
The 10-digit number assigned to providers for identification purposes when submitting services to payers is the NPI, or National Provider Identifier. This format was adopted to improve the efficiency of the healthcare system regarding electronic transmissions and to provide a standardized identifier for health care providers. The NPI is used in administrative and financial transactions as mandated by HIPAA (Health Insurance Portability and Accountability Act).
ICD codes, on the other hand, are used to document diagnoses and are found in medical records and billing documents. They are employed by clinicians to order laboratory tests and prescribe treatments, by medical laboratories to identify required tests, by health-care management systems to verify treatments, by medical coders to assign the proper code for procedures performed, and by medical billers to process insurance claims. Furthermore, ICD codes are used by vital-records keepers in death certificates and by epidemiologists to collect morbidity and mortality statistics.
Two places where you would likely find an ICD code are on a patient's medical record within a clinic or hospital and on a billing statement from healthcare providers or insurance companies.
