ICD-10 Code G44.83 – Primary cough headache (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G44.83 – Primary cough headache
What it is
Primary cough headache is a headache triggered by coughing or other sudden Valsalva maneuvers. It is classified as primary when no underlying structural cause is found.
Clinical signs
Head pain usually starts abruptly with coughing, straining, sneezing, or similar exertion. Clinical features vary; refer to documentation, and rule out secondary causes when the presentation is new or atypical.
When to use this code
Use G44.83 when the record clearly identifies primary cough headache and the clinician has excluded an underlying disorder. Apply it for brief, recurrent headaches specifically linked to coughing or straining. If the note suggests another cause, check documentation before coding.
Do not use for
Do not use this code for cough-related headache with an identified secondary cause, such as another neurologic or intracranial condition. Do not use it when the documentation only says “headache” without the cough trigger.
Coding tip
Confirm both the cough trigger and the “primary” diagnosis in the note before assigning G44.83.
