About coding temporomandibular joint dysfunction
The ICD-10-CM code for temporomandibular joint dysfunction is M26.69 (Other specified disorders of temporomandibular joint). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on M26.69.
Within M26.6, choose M26.69 (Other specified disorders of temporomandibular joint) only when documentation doesn't support a more specific option: temporomandibular joint disorder, unspecified (M26.60), adhesions and ankylosis of temporomandibular joint (M26.61), arthralgia of temporomandibular joint (M26.62), articular disc disorder of temporomandibular joint (M26.63), arthritis of temporomandibular joint (M26.64) and arthropathy of temporomandibular joint (M26.65).
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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 157 (Dental and Oral Diseases with MCC, relative weight 1.809), DRG 158 (Dental and Oral Diseases with CC, relative weight 0.9366) and DRG 159 (Dental and Oral Diseases without CC/MCC, relative weight 0.6893), in Pre-MDC and 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.
