About coding rheumatoid torticollis
The ICD-10-CM code for rheumatoid torticollis is M06.88 (Other specified rheumatoid arthritis, vertebrae).
Within M06.8 (other specified rheumatoid arthritis), M06.88 is specifically for other specified rheumatoid arthritis, vertebrae. Related codes cover unspecified site (M06.80), shoulder (M06.81), elbow (M06.82), wrist (M06.83), hand (M06.84), hip (M06.85), knee (M06.86), ankle and foot (M06.87) and 2 more.
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 545 (Connective Tissue Disorders with MCC, relative weight 2.3892), DRG 546 (Connective Tissue Disorders with CC, relative weight 1.1745) and DRG 547 (Connective Tissue Disorders without CC/MCC, relative weight 0.7526), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
