About the H90–H94 Code Range
ICD-10 codes H90-H94 cover various disorders affecting the ear, focusing mainly on different types of hearing loss, ear pain, discharge, and other specific ear conditions. These codes are essential for identifying and categorizing conductive, sensorineural, mixed, and unspecified hearing losses, as well as ear-related symptoms like otalgia, otorrhea, and tinnitus.
This chapter includes conductive and sensorineural hearing loss codes (H90) with subdivisions for bilateral, unilateral, and unspecified cases, facilitating accurate documentation of conditions like middle ear conductive hearing loss or sensorineural hearing loss, as in presbycusis or sudden idiopathic hearing loss. The codes also cover ototoxic hearing loss (H91.0), which results from drug or toxin exposure. Additionally, it captures other hearing impairments such as auditory recruitment, hyperacusis, diplacusis, and tinnitus (H93), including pulsatile tinnitus (H93.A). For ear symptoms, codes exist for earache (otalgia, H92.0) and ear discharge (otorrhea, H92.1), specifying laterality when needed. The range concludes with disorders of the acoustic nerve (H93.3) and other ear disorders associated with systemic diseases (H94). This detailed coding allows medical coders and healthcare providers to specify ear conditions accurately by type, location, and cause, improving clinical clarity and patient care documentation.
