About M80.8AXS
M80.8AXS is the ICD-10-CM diagnosis code for other osteoporosis with current pathological fracture, other site, sequela. It belongs to category M80 (osteoporosis with current pathological fracture), block M80-M85 (disorders of bone density and structure) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.
Use an additional code to identify major osseous defect, if applicable (M89.7-).
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 559 (Aftercare, Musculoskeletal System and Connective Tissue with MCC, relative weight 1.8088), DRG 560 (Aftercare, Musculoskeletal System and Connective Tissue with CC, relative weight 1.1238) and DRG 561 (Aftercare, Musculoskeletal System and Connective Tissue without CC/MCC, relative weight 0.8258), 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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It was added in FY2021, effective October 1, 2020.
