J37: Chronic laryngitis and laryngotracheitis

J37 refers to Chronic laryngitis and laryngotracheitis, which includes chronic or recurring conditions of the upper respiratory tract involving the nasal passages, sinuses, tonsils, adenoids, vocal cords, and larynx. These are often caused by allergies, infections, or prolonged inflammation.

Symptoms

• Nasal congestion and sneezing – Seen in allergic and vasomotor rhinitis (J30)
• Postnasal drip and throat irritation – Common in chronic pharyngitis or rhinitis (J31)
• Facial pressure and recurrent sinus infections – Hallmarks of chronic sinusitis (J32)
• Nasal obstruction – May indicate nasal polyps (J33) or other sinus disorders (J34)
• Enlarged tonsils or recurrent sore throat – Typical of chronic tonsillitis/adenoiditis (J35)
• Severe throat pain and swelling – Seen in peritonsillar abscess (J36)
• Persistent hoarseness – Related to vocal cord and laryngeal disorders (J37–J38)
• Difficulty breathing or speaking – May occur in J39 disorders or laryngeal issues

Diagnosis

Diagnosis of Chronic laryngitis and laryngotracheitis involves physical exam, nasal endoscopy, laryngoscopy, CT scans for sinus issues, allergy testing, and throat swabs. Long-standing symptoms usually indicate the need for imaging or specialist referral (e.g., ENT).

ICD10 Code Usage

ICD10 code J37 is used by ENT specialists, allergists, pediatricians, family physicians, and pulmonologists. It supports ongoing care, allergy treatment plans, surgery decisions (e.g., polypectomy or tonsillectomy), and long-term medication regimens.

Related Codes

• J30 – Vasomotor and allergic rhinitis
• J31 – Chronic rhinitis, nasopharyngitis and pharyngitis
• J32 – Chronic sinusitis
• J33 – Nasal polyp
• J34 – Other and unspecified disorders of nose and nasal sinuses
• J35 – Chronic diseases of tonsils and adenoids
• J36 – Peritonsillar abscess
• J38 – Diseases of vocal cords and larynx, not elsewhere classified
• J39 – Other diseases of upper respiratory tract

FAQs

Q1: What is ICD10 code J37?
A: It refers to Chronic laryngitis and laryngotracheitis, a group of chronic or structural upper respiratory disorders involving the nose, throat, or voice box.

Q2: What causes these conditions?
A: Often caused by repeated infections, allergies, immune reactions, or anatomical abnormalities like deviated septum or polyps.

Q3: Can nasal polyps (J33) come back after removal?
A: Yes—recurrence is common, especially without managing the underlying inflammation or allergy.

Q4: When is tonsillectomy or adenoidectomy needed?
A: When chronic infections interfere with breathing, sleep, or swallowing, especially in children (J35).

Q5: Who manages these conditions?
A: ENTs, allergists, speech pathologists (for vocal issues), and primary care providers depending on the condition.

Conclusion

ICD10 code J37 helps classify and manage Chronic laryngitis and laryngotracheitis efficiently, supporting clinical decisions for chronic respiratory symptoms, surgical planning, and long-term follow-up.
