M12.321
ICD-10-CMThis code signifies a recurrent, episodic inflammatory arthritis affecting the right elbow, characterized by acute attacks of joint pain, swelling, and stiffness that resolve completely between episodes. Unlike chronic rheumatoid arthritis, palindromic rheumatism does not typically cause permanent joint damage.
Apply this code when documentation clearly indicates a diagnosis of palindromic rheumatism specifically affecting the right elbow joint. Supporting clinical notes should describe the characteristic migratory, self-limiting inflammatory episodes in the specified anatomical location.
