D49.2 — Neoplasm of unspecified behavior of bone, soft tissue, and skin

BillableUnspecified

Is D49.2 billable?

Yes, but D49.2 is an unspecified code. D49.2 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D49.2 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 D49.2 — the more specific alternatives are listed below.

Excludes1 — never code together

The conditions below can never be reported together with D49.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

neoplasm of unspecified behavior of anal canal (D49.0)
neoplasm of unspecified behavior of anus NOS (D49.0)
neoplasm of unspecified behavior of bone marrow (D49.89)
neoplasm of unspecified behavior of cartilage of larynx (D49.1)
neoplasm of unspecified behavior of cartilage of nose (D49.1)
neoplasm of unspecified behavior of connective tissue of breast (D49.3)
neoplasm of unspecified behavior of skin of genital organs (D49.59)
neoplasm of unspecified behavior of vermilion border of lip (D49.0)

Excludes2 — not included here — inherited from D49

The conditions below are not part of D49.2, but a patient may have both at the same time. When documentation supports it, D49.2 and the excluded code may both be reported.

neoplasms of uncertain behavior (D37-D44, D48)

How long has D49.2 existed?

D49.2 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.

Which codes are confused with D49.2?

ICD-10-CM declares these codes mutually exclusive with D49.2 — exactly one of each pair can be correct for a given encounter.
