Other disorders of ear, not elsewhere classified (H93)

The ICD-10 code H93 covers a range of ear disorders that do not fit into other specific categories, including various types of hearing and auditory perception issues. These codes help healthcare providers diagnose and document less common or unspecified ear conditions.

This section includes codes for degenerative and vascular disorders of the ear such as transient ischemic deafness (H93.01), which refers to temporary hearing loss caused by reduced blood flow. The codes also cover tinnitus (H93.1 and H93.A), including pulsatile forms, characterized by ringing, buzzing, or other noises in one or both ears. Other conditions coded here range from auditory recruitment and hyperacusis (heightened sensitivity to sound) to diplacusis (perception of different pitches between ears). Importantly, several codes specify laterality (right, left, bilateral, or unspecified). Additionally, disorders of the acoustic nerve (H93.3) and other specified or unspecified ear disorders are included, aiding in precise coding when common diagnoses are unclear or rare. Using these ICD-10 codes for other disorders of ear, not elsewhere classified ensures accurate classification of diverse ear-related conditions.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Hyperacusis

An abnormally disproportionate increase in the sensation of loudness in response to auditory stimuli of normal volume. COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; FACIAL NERVE DISEASES; STAPES SURGERY; and other disorders may be associated with this condition.

Tinnitus

A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
