Effusion, right foot

This code represents the accumulation of excess fluid within the joint capsule or surrounding soft tissues of the right foot. This fluid buildup, known as an effusion, can be a symptom of various underlying conditions such as inflammation, infection, or trauma.

Use this code when documentation explicitly states "effusion of the right foot" or "fluid in the right foot joint." This code is appropriate for non-specific effusions where the underlying cause is either unknown or coded separately.

• Ensure laterality is clearly documented as "right foot" to support this specific code.
• If the underlying cause of the effusion is known (e.g., osteoarthritis, gout, trauma), code the primary condition first, followed by the effusion.
• Do not use this code for edema (swelling of soft tissues) unless specifically documented as an effusion.
