How is M84.46 listed in the Alphabetic Index?

- Fracture, pathological › fibula (pathologic)
- Fracture, pathological › tibia (pathologic)
Excludes1 — never code together — inherited from M84.4
The conditions below can never be reported together with M84.46 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M84.46, but a patient may have both at the same time. When documentation supports it, M84.46 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 M84.46, but a patient may have both at the same time. When documentation supports it, M84.46 and the excluded code may both be reported.
- traumatic fracture of bone-see fracture, by site
Excludes2 — not included here — inherited from M84.4
The conditions below are not part of M84.46, but a patient may have both at the same time. When documentation supports it, M84.46 and the excluded code may both be reported.
- personal history of (healed) pathological fracture (Z87.311)
