The Difference Between Outpatient Therapy Recertifications and Re-evaluations
These concepts are often confused or used interchangeably, yet they serve very different regulatory and clinical purposes. Understanding the distinction is critical to medical review compliance, CERT risk reduction, and accurate billing.
Certification is the physician’s/nonphysician practitioner’s (NPP) approval of the plan of care. Certification requires a dated signature on the plan of care or some other document that indicates approval of the plan of care.
Outpatient therapy recertification is a regulatory requirement tied to Medicare for payment and coverage, not a clinical service. Medicare requires that the patient’s plan of care be periodically reviewed, dated, and signed by a physician or qualified nonphysician practitioner at least every 90 days, including services provided in comprehensive outpatient rehabilitation facilities, unless delayed certification provisions apply. Recertification confirms the practitioner’s approval of the plan of care and the medical necessity for continued services. It does not require a patient encounter and is not separately billable.
In contrast, re-evaluation provides additional objective information not included in other documentation. Re-evaluation is separately payable and is periodically indicated during an episode of care when the professional assessment of a clinician indicates a significant improvement, or decline, or change in the patient's condition or functional status that was not anticipated in the plan of care. Although some state regulations and state practice acts require re-evaluation at specific times, for Medicare payment, reevaluations must also meet Medicare coverage guidelines. The decision to provide a reevaluation shall be made by a clinician.
In summary, recertification is a time-based administrative requirement necessary to maintain coverage, while re‑evaluation is a patient specific, clinical decision driven by changes in functional status or progress. Clearly distinguishing and appropriately documenting each process is essential to support medical necessity, ensure accurate billing, and reduce audit and review risk.
