Patient presents with complaints of hearing loss, difficulty hearing in noisy environments, andor tinnitus.  Onset of hearing impairment may be gradual or sudden.  Audiological evaluation reveals hearing deficit confirmed by pure-tone audiometry, demonstrating thresholds exceeding normal limits.  Type of hearing loss may be conductive, sensorineural, or mixed.  Degree of hearing loss categorized as mild, moderate, severe, or profound.  Etiology of hearing deficit may be attributed to age-related hearing loss (presbycusis), noise-induced hearing loss, genetic factors, ototoxic medications, prior ear infections, Meniere's disease, acoustic neuroma, or other underlying medical conditions.  Patient's medical history, family history, and current medications reviewed.  Otoscopic examination findings documented.  Treatment plan may include hearing aids, assistive listening devices, cochlear implants, auditory rehabilitation, referral to otolaryngology, or further diagnostic testing such as auditory brainstem response (ABR) or magnetic resonance imaging (MRI) of the internal auditory canal.  Patient education provided regarding hearing loss management and communication strategies.  Follow-up scheduled for audiological reassessment and monitoring of hearing status.  ICD-10 codes such as H90.x and H91.x considered for diagnostic coding and medical billing purposes.  CPT codes for audiological testing and procedures documented for reimbursement.
