Clinical & Coding Specifications
Clinical Context
A 58-year-old woman presents to a prosthetics and orthotics clinic three months after unilateral mastectomy for stage IIB invasive ductal carcinoma. She has completed adjuvant chemotherapy and radiation and requests a comfortable external breast prosthesis to wear inside a bra. The prosthetist evaluates skin condition, residual limb contour, and adhesive compatibility. An adhesive skin support attachment (A4280) is selected to provide secure fixation of the external breast prosthesis to the chest wall when adhesive suspension is preferred over pocketed prostheses. The clinical workflow includes: a focused history and inspection of the surgical site, measurement and fitting of the external prosthesis, selection and application of the adhesive skin support attachment, patient education on application, removal, skin care, replacement frequency, and documentation of device model, size, and any trial use. Follow-up is scheduled to assess fit, skin tolerance, and replacement needs.
