ICD-10 code for site unspecified desmoid

The ICD-10-CM code for site unspecified desmoid is D48.119 (Desmoid tumor of unspecified site).

Within D48.11, choose D48.119 (of unspecified site) only when documentation doesn't support a more specific option: of head and neck (D48.110), of chest wall (D48.111), intrathoracic (D48.112), of abdominal wall (D48.113), intraabdominal (D48.114), of upper extremity and shoulder girdle (D48.115), of lower extremity and pelvic girdle (D48.116), of back (D48.117) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
