Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
- Section I.C.13.d Osteoporosis (page 61), covers M81
Use M81 when there is no current pathologic fracture, adding Z87.310 for a history of osteoporosis fracture. Use M80, not a traumatic fracture code, for a current fracture from trauma that would not break a healthy bone.
Other Chapter 13 topics:
- Site and laterality (page 60)
- Acute traumatic versus chronic or recurrent musculoskeletal conditions (page 61)
- Coding of Pathologic Fractures (page 61)
- Multisystem Inflammatory Syndrome (page 62)
All codes under M81
M81 can't be used on a claim. Pick a billable code below; grey headings group them.
M81 MS-DRGs
As the principal diagnosis, all 3 billable codes under M81 group to MS-DRG 553 or 554 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
Other codes that refer to M81
Notes on these codes point to M81.
About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Osteoporosis
Osteoporosis is a disease in which your bones become weak and are likely to fracture (break). The disease can develop when your bone mineral density and bone mass decrease. It can also happen if the structure and strength of your bones change.
