    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult with symptomatic knee instability or post-operative protection following ligament repair who presents to an orthotics clinic after referral from an orthopedic surgeon or physical therapist. The patient may have diagnoses such as a medial collateral ligament sprain, posterolateral corner injury, or proximal tibial fracture requiring a stabilized knee joint. The clinical workflow begins with an initial evaluation by an orthotist or orthopedic clinician to assess joint range of motion, laxity, swelling, and skin integrity. Measurements are taken for an off-the-shelf double upright knee orthosis with adjustable flexion/extension joints (K0902). The orthosis is sized and fitted in clinic; gait and functional checks are performed, and joint stops are set to prescribed flexion/extension limits. Patient education on donning/doffing, skin checks, and activity restrictions is provided. Follow-up visits occur to confirm fit, adjust joint settings (for example to gradually increase allowed flexion), and document functional progress. If the device cannot be fitted or requires customization, the orthotist documents reasons and communicates with the referring provider for next steps.
