A new code was added for pseudobulbar affect (310.81), which

disturbance or postencephalitic syndrome.
Nervous System Disorders
New codes were added for corticobasal degeneration (331.6)

An additional code was added to describe vitreomacular adhesion (379.27).
A new code was added to describe coronary atherosclerosis
due to calcified coronary lesion (414.4). This code would be assigned in addition to the code for the specific type of coronary

and parietoalveolar pneumopathy, to describe interstitial pneumonia (516.30–516.37), lymphangioleiomyomatosis (516.4),

insufficiency, NEC, following trauma and surgery (518.52), and
acute and chronic respiratory failure following trauma and surgery (518.53).
A new category was added for complications of bariatric procedures (539). The subcategories include 539.0, Complications
of gastric band procedure, and 539.8, Complications of other
bariatric procedure. These two subcategories are further subdivided to the fifth-digit level to describe the type of complication
(i.e., infection or other complications). These codes require additional codes to specify the type of infection (e.g., cellulitis or
septicemia), causative organism, or specific complication.
