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.
The main symptom of croup is a cough that sounds like a seal barking. Most children will have mild cold symptoms for several days before the barking cough becomes evident. As the cough gets more frequent, the child may have trouble breathing or stridor (a harsh, crowing noise made when breathing in). Croup is typically much worse at night. It often lasts 5 or 6 nights. The first night or two are most often the worst. Rarely, croup can last for weeks.
