M95.0Acquired deformity of nose

M95.0 is the ICD-10-CM diagnosis code for acquired deformity of nose. 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), M95.0 is specifically for acquired deformity of nose. Related codes cover Cauliflower ear (M95.1), other acquired deformity of head (M95.2), acquired deformity of neck (M95.3), 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).

The conditions in its Excludes2 note aren't part of M95.0, but may be coded alongside it if the patient has both: deviated nasal septum (J34.2).

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 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), 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 738.0 (acquired deformity of nose).
