To add to what Linda said:
If the patient's insurance company told you this, then you are maybe dealing with a formal definition of "biologically based". By way of introduction to the subject, look at the top of Page 2 and the bottom of Page 5 at the following link. In your state, and at your patient's insurance website, you should be able to find something similar - if it
was the patient's insurance company that said they would pay for something that was "biologically based".
https://www.oxhp.com/secure/policy/behavioral_health_services.pdfBiologically based mental illness: a mental or nervous condition that is caused by a biological disorder of the brain and results in a clinically significant or psychological syndrome or pattern that substantially limits the functioning of the person with the illness. This term is often specifically defined by individual state legislation and, in such cases, the state-defined definition applies.On Page 5 there is a list of conditions, with related codes. Then this statement:
The State of New Jersey considers all conditions not listed above to be non-biologically based, and as such, may be subject to coverage and cost share structures individually defined by the Member's certificate of coverage. The Massachusetts Code specifically recognizes
biologically-based as a category for mental illness, including anxiety disorders:
http://www.malegislature.gov/Laws/GeneralLaws/PartI/TitleIV/Chapter32a/Section22Section 22. (a) The commission shall provide to any active or retired employee of the commonwealth who is insured under the group insurance commission coverage on a nondiscriminatory basis for the diagnosis and treatment of the following biologically-based mental disorders, as described in the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders published by the American Psychiatric Association, referred to in this section as the DSM: (1) schizophrenia; (2) schizoaffective disorder; (3) major depressive disorder; (4) bipolar disorder; (5) paranoia and other psychotic disorders; (6) obsessive-compulsive disorder; (7) panic disorder; ( delirium and dementia; (9) affective disorders; (10) eating disorders; (11) post traumatic stress disorders; (12) substance abuse disorders; and (13) autism.If you are not in the State of New Jersey, I strongly urge you to find out what your own state rules and codes are, rather than simply using the data at the link I provided.
