Not sure where this titillating bit of info should go (if it should go anywhere), so the mods can feel free to remove or relocate as they deem appropriate. Anyway....
The Tax Court recently held that "an individual could deduct as a medical care expense under Code Sec. 213 amounts paid for hormone therapy and sex reassignment surgery that were incurred in connection with a condition known as gender identity disorder, which the Tax Court found to be a disease. However, it found that breast augmentation surgery that the individual also had in connection with the disorder was cosmetic surgery and amounts paid for it were not deductible under Code Sec. 213(d)(9)."
Which, to me, also raises the question of whether a provider can deduct the cost of breast augmentation as a "reasonable and necessary" business expense, or whether such expense is just a non-deductible cosmetic surgery expense.
