What Psychoanalyst covers
Psychoanalysis is a comprehensive, theoretical framework which, when applied to a treatment process, consists of an intensive verbal, therapeutic relationship between an analyst and an analysand which aims for symptom relief, emotional growth, and personal integration. The psychoanalytic treatment process includes, but is not limited to, the recognition of unconscious processes and conflicts; the significance of developmental influences; and the impact of resistances, defenses, transference and countertransference phenomena. Treatment is enhanced by an understanding developed in the analyst's training and personal analysis of unconscious manifestations, such as dreams, slips of the tongue, fantasies and day dreams. Psychoanalytic technique varies in relation to theoretical orientation. NUCC Health Care Provider Taxonomy, code 102L00000X

Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

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 | 2 | 8 | 5 | 7 | 5 | 5 | 3 | 1 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 7 | 5 | 5 | 5 | 1 | 3 | 2 |
Sum = 56 · next multiple of 10 = 60 · check digit = 4 · actual last digit = 4
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.
