Insights

Prior authorization (PA) for total hip arthroplasty (THA) does not reduce costs. Patients requiring PA for THA experienced longer wait times for their procedures, indicating it is not a cost-saving measure.

Area of Science:

  • Orthopedic Surgery
  • Health Services Research
  • Health Economics

Background:

  • Prior authorization (PA) is used by payers to curb healthcare spending.
  • PA may increase administrative burdens and delay patient care.
  • The financial impact and cost-effectiveness of PA for total hip arthroplasty (THA) remain unclear.

Purpose of the Study:

  • To quantify the financial costs associated with obtaining prior authorization (PA) in patients undergoing primary total hip arthroplasty (THA).

Main Methods:

  • A prospective study analyzed 1,788 primary THA patients with commercial insurance (2020-2022).
  • Data collected included PA status, service utilization, and claims costs pre-THA and from surgery request to surgery date.
  • Matched cohorts compared costs and wait times between patients requiring PA and those who did not.

Main Results:

  • No significant difference in mean claims costs was found between patients requiring PA and those who did not, either in the year before THA or from surgery request to surgery.
  • Patients requiring PA experienced a statistically significant longer duration from initial surgery request to THA surgery (43 vs. 39 days).

Conclusions:

  • Prior authorization (PA) is an ineffective cost-saving strategy for primary total hip arthroplasty (THA).
  • PA requirements lead to significantly longer wait times for THA patients, impacting timely access to care.
