2024 ICD-10-CM Diagnosis Code J32.0

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Chronic bilateral maxillary sinusitis
• Chronic left maxillary sinusitis
• Chronic maxillary sinusitis
• Chronic right maxillary sinusitis
• Fistula of nasal sinus
• Maxillary sinusitis
• Oral fistula
• Oroantral communication
• Oroantral fistula

Clinical Information

• Oroantral Fistula-. a fistula between the maxillary sinus and the oral cavity.
• Oral Fistula-. an abnormal passage within the mouth communicating between two or more anatomical structures.
• Maxillary Sinusitis-. inflammation of the nasal mucosa in the maxillary sinus. in many cases, it is caused by an infection of the bacteria haemophilus influenzae; streptococcus pneumoniae; or staphylococcus aureus.
• Chronic Maxillary Sinusitis-. inflammation of the maxillary sinus that typically lasts beyond eight weeks. it is caused by infections, allergies, and the presence of sinus polyps or a deviated septum. signs and symptoms include headache, nasal discharge, swelling in the face, dizziness, and breathing difficulties.
• Maxillary Sinusitis-. an acute or chronic inflammatory process affecting the mucous membrane of the maxillary sinus.

Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
152	OTITIS MEDIA AND URI WITH MCC	03	1.1882
153	OTITIS MEDIA AND URI WITHOUT MCC	03	0.7348

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Patient Education

Sinusitis

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain.

There are several types of sinusitis, including:

• Acute, which lasts up to 4 weeks
• Subacute, which lasts 4 to 12 weeks
• Chronic, which lasts more than 12 weeks and can continue for months or even years
• Recurrent, with several attacks within a year

Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis.

Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.
