C49.2

C49.2 — Malignant neoplasm of connective and soft tissue of lower limb, including hip

Non-billable headerICD-10-CM

C49.2 is a non-billable header ICD-10-CM code for malignant neoplasm of connective and soft tissue of lower limb, including hip. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above C49.2

These are not written on C49.2, but they bind it: a note on a category applies to every code beneath it. Billing C49.2 with anything listed here is a denial.

malignant neoplasm of cartilage (of):
articular (C40-C41)
larynx (C32.3)
nose (C30.0)
malignant neoplasm of connective tissue of breast (C50.-)

Excludes2 inherited from the categories above C49.2

Also inherited, and the opposite of Excludes1: these conditions are not part of C49.2, but a patient can have both, so you may code both.

Written on C49 — Malignant neoplasm of other connective and soft tissue

Kaposi's sarcoma of soft tissue (C46.1)
malignant neoplasm of heart (C38.0)
malignant neoplasm of peripheral nerves and autonomic nervous system (C47.-)

malignant neoplasm of uterine ligament (C57.3)
mesothelioma (C45.-)

Risk adjustment

C49.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

C49.2 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
