Answer: Allodynia is a condition characterized by the patient feeling pain caused by a stimulus that is not usually painful (such as light). Allodynia is covered by the more general term hyperesthesia, or an increased sensitivity.

Note: Hyperalgesia is a condition sometimes tied to allodynia. Hyperalgesia is an increased response to a stimulus that normally is somewhat painful to begin with (such as a pin prick). You currently report hyperalgesia with 782.0 and will shift to R20.8 under ICD-10.
