About coding senile osteomalacia
The ICD-10-CM code for senile osteomalacia is M83.1 (Senile osteomalacia).
Within M83 (adult osteomalacia), M83.1 is specifically for senile osteomalacia. Related codes cover puerperal osteomalacia (M83.0), due to malabsorption (M83.2), due to malnutrition (M83.3), Aluminum bone disease (M83.4), other drug-induced osteomalacia in adults (M83.5), other adult osteomalacia (M83.8) 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.
