What this specialty covers
A person who provides case management services and assists an individual in gaining access to needed medical, social, educational, and/or other services. The person has the ability to provide an assessment and review of completed plan of care on a periodic basis. This person is also able to take collaborative action to coordinate the services with other providers and monitor the enrollee's progress toward the cost-effective achievement of objectives specified in the plan of care. Credentials may vary from an experience in the fields of psychology, social work, rehabilitation, nursing or a closely related human service field, to a related Assoc of Arts Degree or to nursing credentials. Some states may require certification in case management.
Reading the sole-proprietor share
For this specialty, the sole-proprietor share shows how many active records have the sole-proprietor field marked in NPPES; it does not measure all Case Managers/Care Coordinators working independently. The field is self-reported and is an imperfect proxy for private practice, because professionals in this role may work across agencies, health systems, or other organizations regardless of that designation. The NPI total is a count of records, not a direct count of unique people, jobs, patient panels, or service volume.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- Active NPI records may not represent unique people or currently practicing professionals.
- The primary taxonomy may not capture every professional performing case management or care coordination.
- Providers are counted once, by their primary taxonomy code only.
