Patient presents with symptoms suggestive of mastoiditis, including ear pain (otalgia), mastoid tenderness, erythema, and edema.  Symptoms onset reported as [duration].  Associated symptoms may include fever, headache, hearing loss (conductive hearing loss), tinnitus, and otorrhea.  Otoscopic examination reveals [describe findings, e.g., bulging tympanic membrane, perforated tympanic membrane with purulent discharge].  Differential diagnosis includes otitis media, cholesteatoma, and other infections of the ear.  Based on clinical presentation and examination findings, a diagnosis of mastoid disease, specifically [acute mastoiditis, chronic mastoiditis, coalescent mastoiditis], is suspected.  Laboratory studies ordered include [CBC with differential, blood cultures if fever present].  Imaging studies, such as a CT scan of the temporal bones, may be indicated to confirm the diagnosis and evaluate the extent of disease involvement, including possible complications such as subperiosteal abscess, sigmoid sinus thrombosis, or intracranial extension.  Treatment plan includes [oral antibiotics, intravenous antibiotics, myringotomy, mastoidectomy] depending on the severity and progression of the mastoid infection.  Patient education provided regarding medication administration, potential complications, and follow-up care.  Referral to an otolaryngologist (ENT specialist) is [recommended, made].  Return to clinic scheduled in [timeframe] for reevaluation and monitoring of treatment response.  Medical coding considerations include ICD-10 code [specify appropriate code, e.g., H70.0 for acute mastoiditis, H70.1 for chronic mastoiditis] and CPT codes for procedures performed (e.g., myringotomy, tympanocentesis, mastoidectomy).
