J06: Acute upper respiratory infections of multiple and unspecified sites

J06 refers to Acute upper respiratory infections of multiple and unspecified sites, which includes short-term infections affecting the upper respiratory tract such as the nose, throat, sinuses, tonsils, and larynx. These conditions are common, often viral, and usually self-limiting but may occasionally lead to complications.

Symptoms

• Runny nose and nasal congestion – Typical of J00 (common cold)
• Facial pain or pressure – Associated with J01 (sinusitis)
• Sore throat and painful swallowing – Seen in J02 (pharyngitis) and J03 (tonsillitis)
• Hoarseness or loss of voice – Present in J04 (laryngitis)
• Barking cough and stridor – Characteristic of J05 (croup)
• Fever and malaise – Common across all acute upper respiratory infections
• Cough and postnasal drip – Seen in mixed or nonspecific presentations (J06)

Diagnosis

Diagnosis of Acute upper respiratory infections of multiple and unspecified sites is usually clinical, based on physical examination and history. Throat cultures or rapid antigen tests may confirm streptococcal tonsillitis. Imaging is rarely needed unless complications (e.g., sinusitis or epiglottitis) are suspected. Pulse oximetry may be used in cases involving airway compromise.

ICD10 Code Usage

ICD10 code J06 is used by pediatricians, family physicians, general practitioners, and ENT specialists. It supports documentation, symptomatic treatment, antibiotic stewardship, and insurance coding for visits related to acute respiratory symptoms.

Related Codes

• J00 – Acute nasopharyngitis [common cold]
• J01 – Acute sinusitis
• J02 – Acute pharyngitis
• J03 – Acute tonsillitis
• J04 – Acute laryngitis and tracheitis
• J05 – Acute obstructive laryngitis [croup] and epiglottitis

FAQs

Q1: What is ICD10 code J06?
A: It refers to Acute upper respiratory infections of multiple and unspecified sites, an acute infection of the upper respiratory tract involving the sinuses, throat, larynx, or nasal passages.

Q2: Is antibiotic treatment always necessary?
A: No—most cases are viral and resolve without antibiotics. Antibiotics are only used when bacterial infection is confirmed or highly suspected.

Q3: What age group is most affected by J05 (croup)?
A: Croup primarily affects infants and young children between 6 months and 3 years old.

Q4: Can these infections be prevented?
A: Yes—frequent handwashing, vaccination (e.g., flu), and avoiding exposure to sick individuals can reduce risk.

Q5: Who manages these conditions?
A: Primary care physicians, pediatricians, urgent care providers, and ENT specialists depending on severity.

Conclusion

ICD10 code J06 helps accurately identify and manage Acute upper respiratory infections of multiple and unspecified sites, guiding clinical care, patient education, and treatment decisions while supporting epidemiologic tracking and insurance documentation.
