Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| A42243 | CA | Exclusive Provider Organization primary |
This provider holds licence A42243 issued in CA. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.
This NPI does not appear in the PECOS Medicare enrolment file. Providers who do not bill Medicare — or who bill only through a group's enrolment — will not appear here. It is not a sign of any problem with the registration.
What Exclusive Provider Organization covers
(1) An EPO is a form of PPO, in which patients must visit a caregiver that is specified on its panel of providers (is a participating provider). If a visit to an outside(not participating) provider is made the EPO offers very limited or no coverage for the medical service; (2) While similar to a PPO in that an EPO allows patients to go outside the network for care, if they do so in an EPO, they are required to pay the entire cost of care. An EPO differs from an HMO in that EPO physicians do not receive capitation but instead are reimbursed only for actual services provided; (3) An organization identical to a preferred provider organization except that persons enrolled in the plan are eligible to receive benefits only when they use the services of the contracting providers. No benefits are available when non-contracting providers are used, except in certain emergency situations. NUCC Health Care Provider Taxonomy, code 302F00000X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 0 | 0 | 3 | 0 | 0 | 4 | 2 | 6 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 0 | 0 | 8 | 2 | 3 |
Sum = 42 · next multiple of 10 = 50 · check digit = 8 · actual last digit = 8
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
