Communication with the Physician or Other Clinician Managing On-Going Care Post-Fracture for Men and Women Aged 50 Years and Older
High Priority: YES
Measure Type: Process
Submission Methods: Claims, Registry
Description: Percentage of patients aged 50 years and older treated for a fracture with documentation of communication, between the physician treating the fracture and the physician or other clinician managing the patient’s on-going care, that a fracture occurred and that the patient was or should be considered for osteoporosis treatment or testing. This measure is submitted by the physician who treats the fracture and who therefore is held accountable for the communication.
Osteoporosis Management in Women Who Had a Fracture
High Priority: NO
Measure Type: Process
Submission Methods: Claims, Registry
Description: The percentage of women 50-85 years of age who suffered a fracture and who had either a bone mineral density (BMD) test or prescription for a drug to treat osteoporosis in the 180 days after the fracture.
Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to M80.8B2G: its own notes plus those printed at M80.8, M80, and Chapter 13. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- osteoporosis with current fragility fracture
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
- personal history of (healed) osteoporosis fracture (Z87.310)
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)

- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Notes
General instructions on how these codes are used.
- Use an external cause code following the code for the musculoskeletal condition, if applicable, to identify the cause of the musculoskeletal condition
7th Character
Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.
- The appropriate 7th character is to be added to each code from category M80:
- Ainitial encounter for fracture
- Dsubsequent encounter for fracture with routine healing
- Gsubsequent encounter for fracture with delayed healing this code
- Ksubsequent encounter for fracture with nonunion
- Psubsequent encounter for fracture with malunion
- Ssequela

Fractures
A fracture is a break in a bone. Fractures are usually caused by injuries. Since they can sometimes be serious, it's important to get medical care right away if you think you have a fracture.

- M80.8AXG - Other osteopor with current path fracture, other site, 7thG
Questions About M80.8B2GOverview
Is M80.8B2G a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other osteoporosis with current pathological fracture, left pelvis, subsequent encounter for fracture with delayed healing on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character G in M80.8B2G mean?
The final character G reports a subsequent encounter where the other osteoporosis with current pathological fracture, left pelvis is healing more slowly than expected. In this category the CMS Tabular List defines G as "subsequent encounter for fracture with delayed healing".
What MS-DRG does M80.8B2G group to?
When other osteoporosis with current pathological fracture, left pelvis, subsequent encounter for fracture with delayed healing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 559, 521, 522, 561, 560, with relative weights from 0.8258 to 2.8516 depending on complications. Higher weights mean higher Medicare reimbursement.
Is M80.8B2G exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other osteoporosis with current pathological fracture, left pelvis, subsequent encounter for fracture with delayed healing on inpatient claims. The code appears in the Disorders of bone density and structure (M80-M85) range of the CMS exempt list.
Can M80.8B2G be reported with M48.5?
Not as a rule. The Excludes1 note at M80, which applies to M80.8B2G, lists "collapsed vertebra NOS (M48.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
