Localized swelling, mass and lump, upper limb, bilateral

This code signifies the presence of a localized swelling, mass, or lump affecting both upper limbs. It indicates a palpable abnormality in the arm, forearm, wrist, or hand on both sides of the body, without further specification of its nature or etiology.

Apply this code when documentation clearly identifies a localized swelling, mass, or lump present in both the right and left upper extremities. This is appropriate when the provider has not yet determined the definitive diagnosis for the mass, or when the mass is benign and requires no further specific coding.

• Do not use this code if a more specific diagnosis for the mass (e.g., lipoma, cyst, abscess) is known and documented.
• Ensure documentation specifies "bilateral" involvement of the upper limbs; otherwise, use a unilateral code.
• This code is for symptoms; sequence it after any definitive diagnosis if one is established during the same encounter.
