Provider Responsibilities and Authorization

Prior Authorization

Prior Authorization and Medical Necessity Evaluation (Ohio)

Prior authorization and medical necessity evaluation (Ohio): Requests for services that are stated as unproven or that are subject to coverage or quantity limits will be evaluated for medical necessity using Ohio Administrative Code 5160-101. UnitedHealthcare uses InterQual for primary medical/surgical criteria and may use approved UnitedHealthcare Medical Policies, Coverage Determination Guidelines, and Utilization Review Guidelines when InterQual does not have applicable criteria. In the event of a conflict, federal, state (OAC) or contractual requirements govern.

Applies to Ohio only
Evaluation per OAC 5160-101
InterQual® is primary criteria source

Documentation Required

Provider Actions — Documentation and Authorization

Providers must submit the clinical information supporting the requested level of care and any prior authorization requests in accordance with UnitedHealthcare procedures. Documentation should clearly justify the level of care requested (observation vs inpatient) and include relevant history, exam findings, diagnostic results, treatments, response to treatment, and anticipated next clinical steps.

Submit supporting clinical documentation with any prior authorization request
Include history, exam, diagnostics, treatments, and response to treatments
Clearly justify requested level of care

Prior Authorization

Provider Actions — Escalation When No Improvement in 48 Hours

If an individual's condition does not improve within 48 hours while receiving observation services, the provider should submit additional clinical information to support transition to an inpatient level of care. The documentation should explain why continued observation is insufficient and provide objective findings and treatments to justify inpatient admission.

If no improvement within 48 hours, submit additional clinical information to justify inpatient admission
Provide objective findings and treatment response

Denial Risk

Observation Services — Denial Risk for Convenience Use

Observation services are not medically necessary when provided for convenience of the hospital, providers, the individual, or the individual's family, or solely while awaiting placement to another health care facility. Providers should avoid using observation as a substitute for inpatient admission when clinical criteria for inpatient care are met.

Observation not medically necessary for convenience or placement delays
Do not use observation in lieu of inpatient care when inpatient criteria are met
