Localized swelling, mass and lump, lower limb, bilateral

This code signifies the presence of palpable, localized swelling, a mass, or a lump affecting both lower limbs. It describes a physical finding rather than a specific diagnosis, indicating an abnormal accumulation of tissue or fluid in the lower extremities bilaterally.

Use this code when documentation clearly indicates bilateral localized swelling, a mass, or a lump in the lower limbs without a more specific definitive diagnosis. This is appropriate for initial encounters where the etiology is unknown or when the finding itself is the primary reason for the visit. Documentation should specify "bilateral" and "lower limb."

• Do not use this code if a more specific diagnosis for the swelling, mass, or lump is known (e.g., cellulitis, lipoma, edema due to heart failure).
• Ensure the medical record explicitly states the finding is "bilateral" to support this code; otherwise, consider R22.41 or R22.42 for unilateral involvement.
• This code is often a temporary diagnosis and should be replaced with a definitive diagnosis once established.
