2084P0015X Psychosomatic Medicine Physician

Definition

Psychosomatic Medicine is subspecialty in the diagnosis and treatment of psychiatric disorders and symptoms in complex medically ill patients. This subspecialty includes treatment of patients with acute or chronic medical, neurological, obstetrical or surgical illness in which psychiatric illness is affecting their medical care and/or quality of life such as HIV infection, organ transplantation, heart disease, renal failure, cancer, stroke, traumatic brain injury, high-risk pregnancy and COPD, among others. Patients also may be those who have a psychiatric disorder that is the direct consequence of a primary medical condition, or a somatoform disorder or psychological factors affecting a general medical condition. Psychiatrists specializing in Psychosomatic Medicine provide consultation-liaison services in general medical hospitals, attend on medical psychiatry inpatient units, and provide collaborative care in primary care and other outpatient settings.

Where 2084P0015X sits

• Group: Allopathic & Osteopathic Physicians — code 208 of 238 in the group
• Classification: Psychiatry & Neurology
• Specialization: Psychosomatic Medicine 2084P0015X

Choose 2084P0015X over the general Psychiatry & Neurology code when the provider's training or certification is specifically in psychosomatic medicine; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

CMS's taxonomy crosswalk links 2084P0015X to Medicare specialty 86 (Physician/Neuropsychiatry). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 436 practitioners are enrolled under it nationally, and 19 other taxonomy codes map to the same specialty.

Other codes under the same Medicare specialty: 2084A0401X Addiction Medicine (Psychiatry & Neurology) Physician; 2084B0002X Obesity Medicine (Psychiatry & Neurology) Physician; 2084B0040X Behavioral Neurology & Neuropsychiatry Physician; 2084D0003X Diagnostic Neuroimaging (Psychiatry & Neurology) Physician; 2084F0202X Forensic Psychiatry Physician; 2084H0002X Hospice and Palliative Medicine (Psychiatry & Neurology) Physician; 2084N0008X Neuromuscular Medicine (Psychiatry & Neurology) Physician; 2084N0400X Neurology Physician; and 11 more.

If 2084P0015X is not quite right, these codes in other groups share a word with it — often the same field practised by a different kind of provider:

• 173000000X Legal Medicine (Other Service Providers)

Using 2084P0015X

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
