Impairment Diagnoses in Outpatient Physical and Occupational Therapy

How would you like to reduce medical necessity denials in your outpatient therapy services? One way to do that is to ensure your therapists are capturing the impairment diagnoses in the plan of care.

What is Impairment Diagnoses?

Chapter 15 of the Medicare Benefit Policy Manual states:

“a diagnosis (where allowed by state and local law) and description of the specific problem(s) to be evaluated and/or treated. The diagnosis should be specific and as relevant to the problem to be treated as possible. In many cases, both a medical diagnosis (obtained from a physician/NPP) and an impairment-based treatment diagnosis related to treatment are relevant. The treatment diagnosis may or may not be identified by the therapist, depending on their scope of practice. Where a diagnosis is not allowed, use a condition description similar to the appropriate ICD code.

For example, the medical diagnosis made by the physician is stroke; however, the treatment diagnosis or condition description for PT may be abnormality of gait, for OT, it may be hemiparesis (weakness or inability to move on one side of the body), and for Speech, it may be dysphagia (difficulty swallowing).”

Are your therapists consistently denoting an impairment-based treatment diagnosis in the plan of care? If they are, are your coders coding them? Some coders may initially resist the concept of coding the impairment diagnoses. Once they understand that the physician (provider) signs the plan of care thus endorsing the plan and the denoted impairment diagnoses, they understand the appropriateness. It does introduce, however, a need for a process flow redesign.

The coders need to be able to access the plan of care as well as the referral information early in the process. Why does it matter? It matters because the medical diagnosis might not meet the entry criteria that is acceptable to the insurance company and the claim could result in a denial. The therapist should assign an impairment diagnosis in the plan of care which is signed by the physician. Thus, the medical diagnosis and impairment diagnoses can be placed on the claim.
