About coding coccyx pain
The ICD-10-CM code for coccyx pain is M53.3 (Sacrococcygeal disorders, not elsewhere classified).
Within M53 (other and unspecified dorsopathies, not elsewhere classified), M53.3 is specifically for sacrococcygeal disorders, not elsewhere classified. Related codes cover Cervicocranial syndrome (M53.0), Cervicobrachial syndrome (M53.1), spinal instabilities (M53.2), other specified dorsopathies (M53.8) and dorsopathy, unspecified (M53.9).
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 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), 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.
