Is M84.663 billable?
No — M84.663 is a non-billable header code. M84.663 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 M84.663.

Excludes1 — never code together — inherited from M84.6
The conditions below can never be reported together with M84.663 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- pathological fracture in osteoporosis (M80.-)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M84.663, but a patient may have both at the same time. When documentation supports it, M84.663 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 M84.663, but a patient may have both at the same time. When documentation supports it, M84.663 and the excluded code may both be reported.
- traumatic fracture of bone-see fracture, by site
Code also — inherited from M84.6
Two codes may be needed to describe the condition fully. Whether M84.663 is sequenced first depends on the reason for the encounter.

How long has M84.663 existed?
M84.663 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.
