Other respiratory conditions originating in the perinatal period (P28)

Browse all the diagnosis codes used for other respiratory conditions originating in the perinatal period (p28). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Cyanosis - A bluish or purplish discoloration of the skin and mucous membranes due to an increase in the amount of deoxygenated hemoglobin in the blood or a structural defect in the hemoglobin molecule.

Hydrothorax - A collection of watery fluid in the pleural cavity. (Dorland, 27th ed)

Hypercapnia - A clinical manifestation of abnormal increase in the amount of carbon dioxide in arterial blood.

Middle Lobe Syndrome - Atelectasis of the right middle pulmonary lobe, with chronic pneumonitis. (Dorland, 27th ed)

Mouth Breathing - Abnormal breathing through the mouth, usually associated with obstructive disorders of the nasal passages.

Pleural Cavity - Paired but separate cavity within the THORACIC CAVITY. It consists of the space between the parietal and visceral PLEURA and normally contains a capillary layer of serous fluid that lubricates the pleural surfaces.

Pleural Effusion - Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself.

Pleural Effusion, Malignant - Presence of fluid in the PLEURAL CAVITY as a complication of malignant disease. Malignant pleural effusions often contain actual malignant cells.
