Code A4266 specifically refers to which item?

Code A4266 specifically refers to a diaphragm, which is a medical device used in various healthcare contexts, such as for contraception or as a component in certain therapeutic devices. In coding systems such as ICD-10 and CPT, specific codes are assigned to precise items or devices to ensure proper identification, billing, and medical record-keeping.

Using a distinct code like A4266 for a diaphragm helps healthcare providers and payers accurately communicate about the use and supply of medical items. Each medical device or service has a unique code that reflects its clinical use, making it essential for coding accuracy.

In contrast, the other options represent different medical items that fall under separate codes. For instance, a wheelchair has its own designated code related to mobility assistance, a walking cane is coded differently as a supportive device, and an oxygen tank is categorized under respiratory equipment. Each of these has unique characteristics and uses that necessitate their own specific coding to avoid confusion and ensure appropriate healthcare documentation and reimbursement practices.
