About coding Postimmunization arthropathy
The ICD-10-CM code for Postimmunization arthropathy is M02.20 (Postimmunization arthropathy, unspecified site). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M02.20.
Within M02.2, choose M02.20 (unspecified site) only when documentation doesn't support a more specific option: shoulder (M02.21), elbow (M02.22), wrist (M02.23), hand (M02.24), hip (M02.25), knee (M02.26), ankle and foot (M02.27), vertebrae (M02.28) and 1 more.
Code first underlying disease, such as: congenital syphilis [Clutton's joints] (A50.5), enteritis due to Yersinia enterocolitica (A04.6), infective endocarditis (I33.0) and viral hepatitis (B15-B19).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
