Unspecified perichondritis of external ear, unspecified ear

This code signifies inflammation of the perichondrium, the connective tissue covering the cartilage of the external ear, when the specific type of perichondritis and the affected ear are not documented. It indicates an inflammatory process affecting the outer ear's cartilage without further specificity.

Use this code when the medical record clearly states "perichondritis of external ear" but lacks details regarding the cause (e.g., infectious, traumatic) or laterality (left, right, bilateral). This code is appropriate when the provider's documentation is limited to a general diagnosis of perichondritis of the outer ear.

• Avoid using this code if the documentation specifies the type of perichondritis (e.g., infectious, traumatic) or the affected ear.
• Query the provider for greater specificity regarding the etiology and laterality if possible.
• This code is a "catch-all" for unspecified cases; strive for more specific codes when documentation permits.
