Range Overview
high priority
The ICD-10 category M80-M85 pertains to disorders of bone density and structure. These codes are used to document conditions such as osteoporosis, osteomalacia, and other disorders of bone density and structure. The codes in this range are further subdivided based on the type of disorder, the location of the disorder, and whether the condition is postmenopausal, age-related, or due to other causes.
Key Usage Points:
- •Always code to the highest level of specificity, including the type of disorder and its location.
- •Use additional codes to identify any associated conditions or complications.
- •Use combination codes when a single code can describe both the disorder and its manifestation.
- •Remember to code for the cause of the disorder when applicable.
- •Use a code from this range only when the disorder of bone density or structure is confirmed by the provider.
Coding Guidelines
When to Use:
- ✓When a patient has a confirmed diagnosis of osteoporosis.
- ✓When a patient has a confirmed diagnosis of osteomalacia.
- ✓When a patient has a confirmed diagnosis of other specified disorders of bone density and structure.
- ✓When a patient has a confirmed diagnosis of unspecified disorder of bone density and structure.
- ✓When a patient has a confirmed diagnosis of other osteoporosis.
When NOT to Use:
- ✗When the patient's condition is not confirmed by the provider.
- ✗When the patient's condition is due to a disease not covered in this range.
- ✗When the patient's condition is due to a neoplasm.
- ✗When the patient's condition is due to a congenital anomaly.
Code Exclusions
Always verify the patient's condition with the provider before coding.
Documentation Requirements
Documentation for disorders of bone density and structure should include the type of disorder, its location, and its cause if applicable. The provider should also document any associated conditions or complications.
Clinical Information:
- •Type of disorder
- •Location of disorder
- •Cause of disorder
- •Associated conditions or complications
Supporting Evidence:
- •Medical history
- •Physical examination findings
- •Laboratory test results
- •Imaging study results
Good Documentation Example:
Patient has a confirmed diagnosis of osteoporosis of the lumbar spine due to long-term corticosteroid use.
Poor Documentation Example:
Patient has back pain.
Common Documentation Errors:
- âš Not coding to the highest level of specificity
- âš Not coding for the cause of the disorder
- âš Not coding for associated conditions or complications
- âš Not verifying the patient's condition with the provider

Complexity Rating
Coding for disorders of bone density and structure can be complex due to the need to determine the type of disorder, its location, and its cause. Additionally, coding for associated conditions or complications can add to the complexity.
Key Factors:
- â–¸Determining the type of disorder
- â–¸Determining the location of the disorder
- â–¸Determining the cause of the disorder
- â–¸Coding for associated conditions or complications
Specialty Focus
These codes are primarily used by orthopedic surgeons, rheumatologists, and endocrinologists. They are also used by primary care providers and geriatricians.

Clinical Scenarios:
- • A 65-year-old woman with a confirmed diagnosis of postmenopausal osteoporosis of the lumbar spine.
- • A 70-year-old man with a confirmed diagnosis of age-related osteoporosis of the hip.
- • A 55-year-old woman with a confirmed diagnosis of osteomalacia due to vitamin D deficiency.
- • A 60-year-old man with a confirmed diagnosis of osteoporosis of the wrist due to long-term corticosteroid use.
