The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

agents that suppress cough. they act centrally on the medullary cough center. expectorants, also used in the treatment of cough, act locally.

cough lasting for greater than 8 weeks in adults potentially impacting health-related quality of life. chronic cough generally is associated with eosinophilic airway inflammation (e.g., asthma (cough-variant asthma) and non-asthmatic bronchitis, upper airway disorders, gerd and cough hypersensitivity syndrome).

a sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation. it is a protective response that serves to clear the trachea, bronchi, and/or lungs of irritants and secretions, or to prevent aspiration of foreign materials into the lungs.

asthma which is characterized by chronic cough that is nonproductive without other asthmatic symptoms, e.g., wheezing, and paroxysmal dyspnea. cough-variant asthma is accompanied by airway hypersensitivity and may progress to classical asthma without treatment.

conditions in which the primary symptom is headache and the headache cannot be attributed to any known causes.

a respiratory infection caused by bordetella pertussis and characterized by paroxysmal coughing ending in a prolonged crowing intake of breath.

agents that increase mucous excretion. mucolytic agents, that is drugs that liquefy mucous secretions, are also included here.

the symptom of pain in the cranial region. it may be an isolated benign occurrence or manifestation of a wide variety of headache disorders.

a species of gram-negative, aerobic bacteria that is the causative agent of whooping cough. its cells are minute coccobacilli that are surrounded by a slime sheath.

Cough

Coughing is a reflex that keeps your throat and airways clear. Although it can be annoying, coughing helps your body heal or protect itself. Coughs can be either acute or chronic. Acute coughs begin suddenly and usually last no more than 2 to 3 weeks. Acute coughs are the kind you most often get with a cold, flu, or acute bronchitis. Chronic coughs last longer than 2 to 3 weeks. Causes of chronic cough include:

Water can help ease your cough - whether you drink it or add it to the air with a steamy shower or vaporizer. If you have a cold or the flu, antihistamines may work better than non-prescription cough medicines. Children under four should not have cough medicine. For children over four, use caution and read labels carefully.
