L01

L01 is an alphanumeric designation used across different classification and cataloging systems. Its most widely recognized use is in the ICD-10-CM medical coding system, where L01 designates impetigo, a contagious skin infection. The L01 category encompasses related subcodes, L01.0 through L01.9, which specify site and presentation. In medical records and billing, clinicians and coders assign an L01 code to document impetigo for diagnosis, treatment, and epidemiological reporting. The strict structure of ICD-10-CM codes supports standardized data collection, reimbursement, and public health tracking. Documentation typically notes lesion location, severity, and any complications to determine the appropriate subcode.

Outside medicine, L01 is commonly used as a generic code for models, parts, datasets, or catalog entries in various industries. Because these uses are organization-specific, L01 does not have a single universal definition beyond its role as an identifier within a given system. When encountered, the exact meaning of L01 should be determined from the surrounding documentation, product catalogs, or coding manuals.

In summary, L01 most reliably refers to the ICD-10-CM category for impetigo, while its appearance elsewhere serves as a flexible identifier shaped by the context.
