Case Brief Summary & Legal Analysis

General Brief
3 min read

tl;dr: A taxpayer sought to deduct costs for sex reassignment surgery as medical care. The Tax Court held that treatments for Gender Identity Disorder (GID), a recognized mental disorder, are deductible because they treat a “disease” and are not merely cosmetic under the Internal Revenue Code.

Legal Significance: This case established that Gender Identity Disorder is a “disease” for purposes of the I.R.C. § 213 medical expense deduction, clarifying that prescribed treatments like sex reassignment surgery are not per se non-deductible “cosmetic surgery.”

Case Facts & Court Holding

Key Facts & Case Background

The petitioner, Rhiannon O’Donnabhain, was born a genetic male but experienced a lifelong, persistent discomfort with her gender. A licensed psychotherapist diagnosed her with severe Gender Identity Disorder (GID), a mental disorder listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Following the widely accepted Benjamin Standards of Care for GID, her prescribed treatment regimen included psychotherapy, feminizing hormone therapy, and a period of living full-time as a woman. In 2001, upon the recommendation of two mental health professionals, she underwent sex reassignment surgery (SRS), which surgically reconfigured her male genitalia into female genitalia, and breast augmentation surgery. The petitioner incurred and paid $21,741 for these procedures and related costs, which were not reimbursed by insurance. She claimed these expenses as a medical care deduction on her federal income tax return. The Commissioner of Internal Revenue disallowed the deduction, contending that GID was not a “disease” and that the procedures were non-deductible cosmetic surgery under I.R.C. § 213(d)(9).

Court Holding & Legal Precedent

Issue: Do expenses for hormone therapy and sex reassignment surgery, undertaken to treat a diagnosed case of Gender Identity Disorder, qualify as deductible “medical care” under I.R.C. § 213, or are they non-deductible “cosmetic surgery” under § 213(d)(9)?

The court held that expenses for hormone therapy and sex reassignment surgery Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
