Health Share of Oregon, the Medicaid coordinated care organization covering the Portland metro area, violated federal or state rules in 21 of 100 prior-authorization denials a federal audit sampled — a one-in-five failure rate on the exact paperwork that decides whether a Medicaid enrollee’s surgery, medication or dental procedure gets covered. For a family relying on Oregon’s Medicaid program, known as the Oregon Health Plan, the finding lands on the single most consequential piece of mail a member can receive: the letter saying a requested treatment was denied, and whether that denial followed the rules meant to protect them.
The Number Behind the Headline
The Department of Health and Human Services’ Office of Inspector General selected Health Share of Oregon for review because it “had the highest number of denied and appealed service requests of any” coordinated care organization in the state, part of a broader series of OIG audits examining Medicaid managed care denials nationwide. Out of 100 denied service requests OIG sampled, 21 “did not comply with all Federal and State requirements for denying medical services and items, prescription drugs, and dental procedures that required a prior authorization.” Six of those 21 broke more than one rule at once, meaning the raw count of individual violations is higher than 21 even though the headline share — 21 percent, or roughly one denial in five — describes the number of denials with at least one problem.

What Specifically Went Wrong
OIG broke the 21 non-compliant denials down by the exact rule each one broke. The largest category, 13 denials, involved decisions “not made by individuals with appropriate expertise in addressing the enrollees’ medical or oral health needs” — meaning the person who denied a medically necessary request may not have had the clinical background to judge whether it actually was necessary. Seven denial notices either left out contact information the enrollee needed to appeal, or were not translated into the enrollee’s own language when required. Six denial notices went out later than federal and state timelines allow. A smaller number, four, involved Health Share failing to consult with a treating provider before denying a request, and one denial was never communicated to the provider who submitted it at all.
From a Sample of 100 to an Estimate for the Whole Plan
OIG did not stop at describing its 100-case sample. Using standard statistical extrapolation, the audit projected that 5,677 denied service requests requiring prior authorization — 21 percent of all such denials Health Share issued — failed to comply with federal or state requirements during calendar year 2023 alone. That figure turns a sample-level finding into a plan-wide one: it is OIG’s estimate of how many Oregon Health Plan members, in a single year, received a denial that did not follow the rules governing whether their care could be turned down in the first place, regardless of whether the underlying medical decision would have been upheld on a properly conducted review.
What a Wrongly Denied Prior Authorization Costs a Family
A prior-authorization denial is not just paperwork — it is the decision point where a family either pays for care out of pocket, delays it, or goes without it while pursuing an appeal. When the denial itself was decided by someone without the right clinical expertise, arrived without the contact information needed to challenge it, or showed up late, the enrollee loses time, and sometimes money, fighting a process failure rather than the medical merits of their case. For a family already managing a Medicaid enrollee’s care, an improperly handled denial can mean weeks of delay for a procedure, a prescription filled at full retail price while an appeal is pending, or a bill from a provider who was never told the service had been denied and therefore never told the patient either. Oregon Health Plan members and providers submit and track these prior-authorization requests through the Oregon Health Authority, the same process OIG found Health Share was mishandling in one denial out of five.
How Health Share Responded
OIG made four recommendations to Health Share, aimed at tightening its own quarterly reviews of denial notices, requiring subcontractors to update how they notify providers, clarifying when subcontractors must consult providers before denying a request, and improving what data subcontractors report on denial decisions. Health Share “concurred with three of our recommendations, partially concurred with the remaining recommendation, and provided information on actions that it has taken and planned to take to address our recommendations,” according to OIG. All four recommendations remain listed as “Open Unimplemented” in OIG’s recommendation tracker, with Health Share’s own target date for updates set at February 12, 2027.
Why This One Plan, and What It Signals
Health Share of Oregon was not selected at random — OIG chose it specifically because its denial and appeal volume was the highest of any coordinated care organization in the state, which means the 21 percent failure rate describes the plan most likely to generate disputes in Oregon’s Medicaid managed care system, not necessarily the state average. OIG has been running this same audit format against Medicaid managed care organizations elsewhere in the country, meaning Oregon’s result is one data point in a larger pattern of federal scrutiny on whether state Medicaid plans are following the specific procedural rules — not just the medical judgment calls — behind the denials they issue.
What a Federal Audit Does Not Hand an Enrollee: The Paperwork Trail
An audit like this one identifies a plan’s pattern of mistakes after the fact, but it does not produce the specific renewal calendar, document checklist or reporting deadline an individual Oregon Health Plan household needs to keep coverage active in the meantime.
