2009

The year this clinician's National Provider Identifier (NPI) was issued. An NPI is a unique 10-digit ID that US health care providers use for billing.

Medicare assignment not listed

CMS data do not show whether this clinician accepts Medicare assignment. This does not mean they do not accept Medicare. Ask the office.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

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.
