Diagnosis codes don't tell the whole story of a person, yet we need them to help patients get support through their insurance. Headway recognizes that for some people, putting a name to their struggle can be useful — and to others it can feel limiting or dismissive. That can and should be a part of conversations with your client.
That said, it’s still important to educate yourself about diagnosis and billing codes so that clients experiencing things like gender dysphoria can receive care. Coding exists primarily for insurance reimbursement, medical documentation, and access to gender-affirming care, not to label someone as "disordered.”
ICD codes for gender dysphoria fall under F code 64, or gender identity disorders. When using a code in an insurance claim, choose the one that most closely aligns with your diagnosis. It’s important to note that the most recent ICD-10 codes vernacular was published in 1990, which means the language around them is considered outdated and stigmatizing in most clinical and social contexts. Keep this in mind when reviewing and documenting, and in discussions with your clients. Specific ICD codes for gender dysphoria include:
- Transsexualism (F64.0): A strong and persistent desire to live as the opposite sex, often accompanied by a wish for medical transition such as hormones or surgery.
- Dual role transvestism (F64.1): The act of dressing in clothes of the opposite sex to experience temporary identification, without a desire for permanent gender transition.
- Gender identity disorder of childhood (F64.2): A marked incongruence between a child’s assigned sex and experienced gender, typically involving strong cross-gender identification and discomfort with their own sex.
- Other gender identity disorders (F64.8): A category for gender identity presentations that don't meet the criteria for the more specific F64 codes.
- Gender identity disorder, unspecified (F64.9): Used when gender identity concerns are present but don’t fit into any defined category, or when there’s insufficient information for a more specific diagnosis.
In the case of gender identity disorders in the ICD-10, providers prefer the term “gender dysphoria” as it speaks to the distress associated with the incongruence between one's sex assigned at birth and their experienced gender — not the identity itself.
Relatedly, not all transgender or non-binary people seeking therapy experience dysphoria, nor do they always need medical or psychological interventions. The codes listed above are specifically for clients who are pursuing treatment to address the distress associated with their gender identity. For those clients, it can be very important to document and diagnose the distress they are experiencing if they plan to pursue gender-affirming surgery at any point.
