M80.0B9P Age-related osteoporosis with current pathological fracture, unspecified pelvis, subsequent encounter for fracture with malunion

Billable ICD-10-CM code, FY2026.

Built from M80.0B9 with 7th character P (subsequent encounter for fracture with malunion).

Applies from M80 Osteoporosis with current pathological fracture

Includes

• osteoporosis with current fragility fracture

Excludes1 (never code together)

• collapsed vertebra NOS (M48.5)
• pathological fracture NOS (M84.4)
• wedging of vertebra NOS (M48.5)

Excludes2 (not included here)

• personal history of (healed) osteoporosis fracture (Z87.310)

Use additional code

• code to identify major osseous defect, if applicable (M89.7-)

7th character note

• The appropriate 7th character is to be added to each code from category M80:

7th character required

• A — initial encounter for fracture
• D — subsequent encounter for fracture with routine healing
• G — subsequent encounter for fracture with delayed healing
• K — subsequent encounter for fracture with nonunion
• P — subsequent encounter for fracture with malunion
• S — sequela

Applies from M80.0 Age-related osteoporosis with current pathological fracture

Applicable to

• Involutional osteoporosis with current pathological fracture
• Osteoporosis NOS with current pathological fracture
• Postmenopausal osteoporosis with current pathological fracture
• Senile osteoporosis with current pathological fracture

Medicare Code Edits (MCE v43.1 (April 2026))

• Adult diagnoses (age 15 through 124): Age conflict edit. These diagnoses are clinically expected only in patients age 15 through 124.
• Unspecified code (laterality): Unspecified codes for which a more specific code identifying laterality (right, left, bilateral) exists within the same code family.
