At every level of the spine, a pair of nerve roots runs through the spinal column via small openings called foramina (singular: foramen).
When claims are entered into the Medicare system, they are issued a tracking number known as the internal control number (âICNâ). The ICN is a 13-digit number assigned to each claim received by Medicare. The significance of the digits is as follows: 1  Digits 1-2: Indicate how the claim was submitted (electronically or via paper). 2  Digits 3-4: Indicate the calendar year in which the claim was received.
ICANN stands for the Internet Corporation of Assigned Names and Numbers. It is the governing body over all domain extensions/TLDs with the exception of country codes (TLDs with 2 letters to the right of the dot). TLD stands for Top-Level Domain and the n stands for New, i.e. New Top-Level Domain. A TLD in general is basically the string of characters that follows your domain name. For example, in the domain myawesomedomain.com, the TLD or domain extension is .COM.
