**ICD Code Conversion for Benign Paroxysmal Positional Vertigo (BPPV):**  The patient presents with complaints of episodic vertigo, triggered by specific head movements, consistent with benign paroxysmal positional vertigo.  Symptoms include brief episodes of spinning sensation, dizziness, nausea, and imbalance.  The patient denies any associated tinnitus, hearing loss, or other neurological deficits.  On physical examination, the Dix-Hallpike maneuver elicited a characteristic nystagmus, confirming the diagnosis of BPPV.  The patient's medical history is unremarkable for any central nervous system disorders or significant trauma.  ICD-10 code H81.1 (Benign paroxysmal positional vertigo) accurately reflects the clinical presentation and diagnostic findings.  This replaces the previously used ICD-9 code 386.11 (Vertigo, benign paroxysmal, specified as recurrent).  The treatment plan includes canalith repositioning maneuvers (Epley maneuver) to address the displaced otoconia within the semicircular canals.  Patient education regarding triggers and self-management strategies was also provided.  Follow-up appointment scheduled to assess symptom resolution and efficacy of treatment intervention.  Medical coding and billing documentation updated to reflect the ICD-10 code conversion.


**ICD Code Conversion for Acute Otitis Media (AOM):**  Patient presents with acute onset of ear pain, otalgia, and fever consistent with acute otitis media.  Examination reveals a bulging tympanic membrane with erythema and reduced mobility.  The patient reports recent upper respiratory infection symptoms.  No evidence of otorrhea or mastoid tenderness was observed.  Based on the clinical findings, the diagnosis of acute otitis media is confirmed.  ICD-10 code H66.90 (Acute otitis media, unspecified) is assigned, replacing the previously used ICD-9 code 382.9 (Otitis media, acute, unspecified). This code accurately reflects the diagnosis and facilitates accurate medical billing and coding.  Treatment plan includes a course of antibiotics to address the bacterial infection.  Patient education on pain management and potential complications was provided.  Follow-up appointment scheduled to assess treatment response and resolution of symptoms.  Electronic health record documentation updated with the appropriate ICD-10 diagnosis code.


**ICD Code Conversion for Essential Hypertension:** The patient presents for routine follow-up of essential hypertension. Blood pressure readings consistently elevated above 14090 mmHg on multiple occasions.  Patient reports adherence to prescribed antihypertensive medication.  No reported symptoms of headache, dizziness, or chest pain.  Physical examination unremarkable except for elevated blood pressure.  Lab results within normal limits.  Diagnosis of essential hypertension confirmed.  ICD-10 code I10 (Essential primary hypertension) is assigned, replacing the previously used ICD-9 code 401.9 (Essential hypertension, unspecified). This code accurately reflects the chronic nature of the condition and facilitates accurate healthcare documentation for medical billing and coding.  The treatment plan includes continuing the current antihypertensive medication regimen and emphasizing lifestyle modifications, including diet and exercise, for blood pressure management.  Patient education regarding the importance of medication adherence and regular monitoring was reinforced.  Follow-up appointment scheduled to monitor blood pressure control and assess treatment efficacy.  EHR documentation updated to reflect the ICD-10 code conversion for essential hypertension.
