Localized swelling, mass and lump of skin and subcutaneous tissue (R22)
R22 codes cover localized swelling, masses, and lumps found in the skin and subcutaneous tissue. These codes specify the affected body region such as the head (R22.0), neck (R22.1), trunk (R22.2), upper limbs (R22.3 subcodes), and lower limbs (R22.4 subcodes), or can remain unspecified (R22.9).
The ICD-10 code for localized swelling or lump helps identify exactly where a swelling or mass is located, whether it's a nodule on the skin or a subcutaneous lump. For example, R22.0 includes swellings in the head area, also known by terms such as nasal dermoid, facial swelling, or mass of lip. Similarly, R22.1 covers nodules and masses of the neck region, encompassing parotid gland masses or tonsillar swelling. Upper limb codes like R22.31 and R22.32 designate right or left localized swellings, with synonyms including cysts, nodules, or lumps on the fingers, forearm, or shoulder. Lower limb codes such as R22.41 and R22.42 refer to nodules or masses on feet, calves, or toes. The unspecified code R22.9 is used when swelling or lump location is not detailed. These codes guide proper documentation of skin and soft tissue swelling in medical records.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
