M84.573D — Pathological fracture in neoplastic disease, unspecified ankle, subsequent encounter for fracture with routine healing

BillableUnspecified

Is M84.573D billable?

Yes, but M84.573D is an unspecified code. M84.573D is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, M84.573D is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting M84.573D — the more specific alternatives are listed below.

The conditions below are not part of M84.573D, but a patient may have both at the same time. When documentation supports it, M84.573D 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-)

  • 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 M84.573D, but a patient may have both at the same time. When documentation supports it, M84.573D 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 M84.573D is sequenced first depends on the reason for the encounter.

  • underlying neoplasm

How long has M84.573D existed?

M84.573D 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.
