About coding chest mass
The ICD-10-CM code for chest mass is R22.2 (Localized swelling, mass and lump, trunk).
Within R22 (localized swelling, mass and lump of skin and subcutaneous tissue), R22.2 is specifically for localized swelling, mass and lump, trunk. Related codes cover head (R22.0), neck (R22.1), upper limb (R22.3), lower limb (R22.4) and unspecified (R22.9).
Don't report R22.2 together with the conditions in its Excludes1 note: intra-abdominal or pelvic mass and lump (R19.0-) and intra-abdominal or pelvic swelling (R19.0-).
The conditions in its Excludes2 note aren't part of R22.2, but may be coded alongside it if the patient has both: breast mass and lump (N63).
Don't confuse with (Excludes1 for R22.2)
