About coding rheumatoid arthritis screening
The ICD-10-CM code for rheumatoid arthritis screening is Z13.828 (Encounter for screening for other musculoskeletal disorder).
Within Z13.82, choose Z13.828 (other musculoskeletal disorder) only when documentation doesn't support a more specific option: osteoporosis (Z13.820).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
