Understanding Medical Necessity: Elevating the Role of Clinical Documentation

Medical necessity is a term frequently encountered in O&P—particularly in the context of insurance coverage, audits, and appeals. Yet despite its ubiquity, it remains widely misunderstood. A common misconception persists, that reimbursement decisions are based solely on the treating practitioner’s (e.g., MD, DO, NP, PA, CNS) medical records, rendering the prosthetist or orthotist’s documentation secondary or even irrelevant. This belief is not only inaccurate—it’s costly. According to the Social Security Act (Section 1834 (42 U.S.C. 1395m)), “Documentation created by an orthotist or prosthetist shall be considered part of the individual’s medical record to support documentation created by eligible professionals described in section 1848(k)(3)(B).”

In practice, the quality of orthotic and prosthetic professionals’ clinical documentation plays a critical role in determining claim outcomes. Increasingly, denials and recoupments are being traced back to insufficient or incomplete clinician notes. This is a challenge we have the power to address.
