M81.0Age-related osteoporosis without current pathological fracture

M81.0 is the ICD-10-CM diagnosis code for age-related osteoporosis without current pathological fracture. It belongs to category M81 (osteoporosis without 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.

Within M81, choose M81.0 (Age-related osteoporosis without current pathological fracture) only when documentation doesn't support a more specific option: localized osteoporosis [Lequesne] (M81.6) and other osteoporosis without current pathological fracture (M81.8).

Use an additional code to identify: major osseous defect, if applicable (M89.7-) and personal history of (healed) osteoporosis fracture, if applicable (Z87.310).

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.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 733.00 (osteoporosis, unspecified) and 733.01 (senile osteoporosis).
