Primary blast injury of right ear, sequela

This code signifies a long-term or late-effect condition resulting from a primary blast injury specifically affecting the right ear. It indicates that the initial blast trauma has led to a persistent medical issue, such as chronic hearing loss, tinnitus, or vestibular dysfunction, that is now being treated or evaluated.

Use this code when documenting a patient presenting with a current ear condition that is a direct consequence of a primary blast exposure to the right ear, occurring at some point in the past. Documentation should clearly link the current ear pathology to a previous blast injury and specify the right ear.

• Always sequence this code after the code for the specific sequela (e.g., H90.3 for sensorineural hearing loss).
• Ensure documentation explicitly states "sequela" or "late effect" of a primary blast injury to the right ear.
• Do not use for acute blast injuries; those would be coded with the acute injury codes from the S09 category.
