In an effort to attempt to get some of my therapy paid for by out of network insurance coverage, I asked my therapist to write me up invoices for January and February. We briefly discussed what diagnosis codes she should use. I was overwhelmed by the conversation at the time and ultimately indifferent to the code choices. I just told her to write whatever seemed most appropriate. 

Today she gave me those invoices. Here’s a screenshot showing the codes she chose:

90834 is a CPT code just indicating that she sees me for individual psychotherapy. 

F44.81 is an International Classification of Diseases, 10th edition (ICD-10) code. I honestly wasn’t sure what my therapist would put for this. I figured it would be genereric, like “anxiety disorder” or “mood disorder – unspecified”, which is what Zooey always listed on her invoices, and what my psychiatrists frequently use. 

But I looked up the code and here is what it says online:

F44.81 – Dissociative Identity Disorder 

This is a specific ICD-10-CM code that can be used to specify a diagnosis. This is the American ICD-10-CM version of F44.81. Other international ICD-10 versions may differ.

Clinical Information:

  • A disorder characterized by the presence of two or more identities with distinct patterns of perception and personality which recurrently take control of the person’s behavior; this is accompanied by a retrospective gap in memory of important personal information that far exceeds ordinary forgetfulness. The changes in identity are not due to substance use or to a general medical condition.
  • A dissociative disorder in which the individual adopts two or more distinct personalities. Each personality is a fully integrated and complex unit with memories, behavior patterns and social friendships. Transition from one personality to another is sudden.

Applicable To: Multiple personality disorder. 

ICD-10-CM F44.81 is grouped within Diagnostic Related Group (MS-DRG v32.0): 883 Disorders of personality and impulse control. 

I know this is not news to you (or me), but this is the first time I have ever actually seen this on paper for myself. 
This is real

I really have this. I have officially (on paper I can see with my own eyes) been diagnosed with Dissociative Identity Disorder. My therapist believes me. And she believes me with enough conviction to bill my insurance using that specific code. 

Holy shit. I have a lot of feels right now.
