About coding nose collapse
The ICD-10-CM code for nose collapse is M95.0 (Acquired deformity of nose). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M95.0.
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.
