ABN stands for Advanced Beneficiary Notification. An ABN must be signed prior to providing a Medicare service or test to document that the patient is willing to assume responsibility for payment of services that Medicare may not cover when subject to either National or Local Coverage Determinations (NCD) or (LCD).
Chinchillas are crepuscular (most active around dawn and dusk) rodents, slightly larger and more robust than ground squirrels. They are native to the Andes mountains in South America and live in colonies called  herds  at high elevations up to 4,270 m (14,000 ft).
Chinchilla babies are known as 'kits'. A healthy chinchilla kit is born fully able with its eyes open, body covered in fur and all 20 teeth present. A newborn healthy chinchilla baby/kit weighs between 35-60 grams and reaches its full size within 18 - 24 months (although some kits will continue to develop until they are 3 - 4 years old).
