M84.550 — Pathological fracture in neoplastic disease, pelvis
Is M84.550 billable?
No — M84.550 is a non-billable header code. M84.550 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 6 billable codes beneath M84.550.

- Fracture, pathological › due to › neoplastic disease NEC › ischium (pathologic)
- Fracture, pathological › due to › neoplastic disease NEC › pelvis (pathologic)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M84.550, but a patient may have both at the same time. When documentation supports it, M84.550 and the excluded code may both be reported.
- 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)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- 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)
Excludes2 — not included here — inherited from M84
The conditions below are not part of M84.550, but a patient may have both at the same time. When documentation supports it, M84.550 and the excluded code may both be reported.
- traumatic fracture of bone-see fracture, by site
Code also — inherited from M84.5
Two codes may be needed to describe the condition fully. Whether M84.550 is sequenced first depends on the reason for the encounter.
- underlying neoplasm

How long has M84.550 existed?
M84.550 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
