Coders should be assessing their knowledge of anatomy and physiology and preparing for ICD-10-CM/PCSâs more detailed documentation requirements for code capture. The upcoming series of articles will review and discuss the various anatomy and physiology body systems as well as how ICD-10-CM/PCS is impacted by them.
The incubation period, the time from exposure to HPIV to onset of symptoms, is generally 2 to 7 days. 1  HPIV-1 and HPIV-2 are most often associated with croup. 2  HPIV-1 often causes croup in children, whereas HPIV-2 is less frequently detected.he incubation period, the time from exposure to HPIV to onset of symptoms, is generally 2 to 7 days. 1  HPIV-1 and HPIV-2 are most often associated with croup. 2  HPIV-1 often causes croup in children, whereas HPIV-2 is less frequently detected.
Adult croup patients usually sense the starting of a respiratory infection of the upper airways during the croup incubation period of two to four days. In this period, a low-grade fever, rhinorrhea and a mild cough are the only symptoms that appear. Later on, inflammation, erythema and exudate are caused because of release of inflammatory factors resulting in cough. The cough of croup resembles the sound made by seals and makes a harsh barking noise.
