(IRS announces acquiescence in O'Donnabhain v. Comr., 134 T.C. 34 (2010) in which the court held that petitioner's medical expenses associated with psychological discomfort deductible medical expenses under I.R.C. Sec. 213; hormone therapy and sex reassignment surgery were expenses associated with curing petitioner's psychological disorder and were not non-deductible cosmetic surgery; but breast augmentation surgery was directed at improving petitioner's appearance and not associated with petitioner's psychological disorder; no mention of whether such expenses, if incurred by parents of newborn baby on behalf of baby, would be deductible medical expenses).
