Abstract Background Macromastia is associated with increased opioid consumption, which could potentially be the initial exposure for patients with an opioid use disorder amid an escalating opioid crisis in the United States. Objectives The purpose of this study was to evaluate outpatient cost of care and opioid consumption in patients with macromastia and compare those who underwent reduction mammaplasty vs those who did not have surgery. Methods PearlDiver, a database encompassing a national cohort of private payers with 153 million unique patients, was queried. The study cohort included patients diagnosed with macromastia who did or did not undergo reduction mammaplasty utilizing both ICD-9 and ICD-10 and CPT codes. Outpatient cost of care and morphine milligram equivalents (MME) were calculated up to 5 years postoperatively for both cohorts. Results At 1 to 3 years postoperatively, there was no statistically significant difference in outpatient cost of care between cohorts. At every follow-up thereafter, outpatient cost of care was higher among macromastia patients who did not undergo reduction mammaplasty, with cohort differences of US$240.68 and US$349.90 at 4 years and 5 years, respectively (P < .05). MME consumption was greater in patients who underwent reduction mammaplasty up to 30 days postoperatively (P < .01). Beyond that, there was no significant difference in MME consumption between cohorts. However, patients who did not undergo surgery had opioid consumption levels above 50 MME/day until 3 years after diagnosis of macromastia. Conclusions Patients with macromastia who undergo reduction mammaplasty have lower outpatient care costs than patients who do not undergo reduction mammaplasty, with safer long-term opioid consumption in alignment with current Centers for Disease Control and Prevention guidelines.
