The following is a list of "Z" codes for Medical Subject Headings (MeSH), as defined by the United States National Library of Medicine (NLM). This list continues the information at List of MeSH codes (V04). For other MeSH codes, see List of MeSH codes. The source for this content is the set of 2006 MeSH Trees from the NLM.

It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. [2]
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
[13] [15] Pneumonia is also the leading cause of death in children less than five years of age in low income countries. [15] The most common cause of pneumonia is pneumococcal bacteria, Streptococcus pneumoniae accounts for 2/3 of bacteremic pneumonias. [16] Invasive pneumococcal pneumonia has a mortality rate of around 20%. [14]
While pneumonia is a localized infection, pneumonitis is widespread. [3] A spirometer may also be used to measure pulmonary function. During external examination, clubbing (swelling of fingertip tissue and increase in angle at the nail bed), [14] and basal crackles may be observed.
The latter is a block. In the ICD-11 MMS, blocks never have codes, and not every entity necessarily has a code, although each entity does have a unique id. [31] In the ICD-10, the next level of the hierarchy is indicated in the code by a dot and a single number (e.g. P35.2).
