Clinical Classification Guidelines
Medical Intelligence & Overview
H70.899 refers to unspecified other mastoiditis and related conditions affecting the ear. Mastoiditis is an infection that affects the mastoid bone located behind the ear. When the condition is unspecified, it means that the exact type or cause has not been detailed, but the diagnosis involves inflammation or infection in that region. This condition often develops as a complication of an ear infection and can lead to various symptoms and health concerns if not properly managed.
Causes & Symptoms
Clinical Causes: Bacterial infections originating from untreated or severe middle ear infections (otitis media). Spread of infection from the middle ear into the mastoid bone. Previous ear surgeries that may disrupt normal ear anatomy. Underlying immune system deficiencies that reduce infection resistance. Chronic ear infections that are inadequately treated. Obstruction in ear drainage pathways leading to fluid buildup and infection.
Key Symptoms: Pain behind or around the ear, which may be persistent or worsening. Swelling or tenderness behind the ear where the mastoid bone is located. Fever and general signs of infection such as chills or fatigue. Redness and warmth over the affected area. Hearing loss or muffled hearing in the affected ear. Discharge from the ear, which may be foul-smelling. Feeling of fullness or pressure in the ear. Occasionally, headache and neck stiffness.
Diagnostic & Treatment

Healthcare providers often utilize imaging tests such as CT scans or MRI to assess the mastoid bone's condition and identify the extent of the infection. Ear examinations and microbiological cultures may be conducted to identify the infectious organism and guide treatment. Blood tests may also assist in evaluating the severity of infection and systemic involvement.
Treatment Protocols: Treatment options aim to eliminate infection, alleviate symptoms, and prevent complications. They typically include:
