About coding pelvis osteomalacia
The ICD-10-CM code for pelvis osteomalacia is M83.8 (Other adult osteomalacia).
Within M83, choose M83.8 (Other adult osteomalacia) only when documentation doesn't support a more specific option: puerperal osteomalacia (M83.0), senile osteomalacia (M83.1), due to malabsorption (M83.2), due to malnutrition (M83.3), Aluminum bone disease (M83.4), other drug-induced osteomalacia in adults (M83.5) and unspecified (M83.9).
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 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), 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.
