Onychia is an inflammation of the nail folds (surrounding tissue of the nail plate) of the nail with formation of pus and shedding of the nail. Onychia results from the introduction of microscopic pathogens through small wounds.
A Remittance Advice (RA) is a notice of payments and adjustments sent to providers, billers, and suppliers. After a claim has been received and processed, a Medicare contractor produces the RA, which may serve as a companion to a claim payment(s) or as an explanation when there is no payment.
The amount remitted is the amount sent to a bill collector as a payment. For instance if a credit card company charges you 50 dollars and the minimum payment is 25 dollars you would send them a payment for 25 dollars that month so 25 dollars is the amount remitted. Remitted is related to the word remission.
