About coding skull acquired deformity
The ICD-10-CM code for skull acquired deformity is M95.2 (Other acquired deformity of head). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M95.2.
Within M95, choose M95.2 (Other acquired deformity of head) only when documentation doesn't support a more specific option: acquired deformity of nose (M95.0), Cauliflower ear (M95.1), 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).
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.
