About coding Ecchondrosis
The ICD-10-CM code for Ecchondrosis is D48.0 (Neoplasm of uncertain behavior of bone and articular cartilage).
Within D48 (neoplasm of uncertain behavior of other and unspecified sites), D48.0 is specifically for neoplasm of uncertain behavior of bone and articular cartilage. Related codes cover behavior of connective and other soft tissue (D48.1), behavior of peripheral nerves and autonomic nervous system (D48.2), behavior of retroperitoneum (D48.3), behavior of peritoneum (D48.4), behavior of skin (D48.5), behavior of breast (D48.6), behavior of other specified sites (D48.7) and behavior, unspecified (D48.9).
Don't report D48.0 together with the conditions in its Excludes1 note: neoplasm of uncertain behavior of cartilage of ear (D48.1-), neoplasm of uncertain behavior of cartilage of larynx (D38.0), neoplasm of uncertain behavior of cartilage of nose (D38.5), neoplasm of uncertain behavior of connective tissue of eyelid (D48.1-) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
