What J31 covers · when clinicians use it
ICD-10 code J31 identifies Chronic rhinitis, nasopharyngitis and pharyngitis in the U.S. ICD-10-CM clinical and billing record set. It sits within the Respiratory System chapter (J00–J99), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply J31 when an encounter's findings match the Chronic rhinitis, nasopharyngitis and pharyngitis description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify J31 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for J31 and is a coding reference, not clinical, diagnostic, or billing advice.
J31 refers to Chronic rhinitis, nasopharyngitis and pharyngitis, 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 rhinitis, nasopharyngitis and pharyngitis 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 J31 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.

FAQs
Q1: What is ICD10 code J31?
A: It refers to Chronic rhinitis, nasopharyngitis and pharyngitis, 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 J31 helps classify and manage Chronic rhinitis, nasopharyngitis and pharyngitis efficiently, supporting clinical decisions for chronic respiratory symptoms, surgical planning, and long-term follow-up.
