About M95.3

M95.3 is the ICD-10-CM diagnosis code for acquired deformity of neck. It belongs to category M95 (other acquired deformities of musculoskeletal system and connective tissue), block M95 (other disorders of the musculoskeletal system and connective tissue) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M95 (other acquired deformities of musculoskeletal system and connective tissue), M95.3 is specifically for acquired deformity of neck. Related codes cover acquired deformity of nose (M95.0), Cauliflower ear (M95.1), other acquired deformity of head (M95.2), acquired deformity of chest and rib (M95.4), acquired deformity of pelvis (M95.5), other specified acquired deformities of musculoskeletal system (M95.8) and acquired deformity of musculoskeletal system, unspecified (M95.9).

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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 738.2 (acquired deformity of neck).
