About coding basal metabolic rate elevated
The ICD-10-CM code for basal metabolic rate elevated is R94.8 (Abnormal results of function studies of other organs and systems).
Within R94, choose R94.8 (of other organs and systems) only when documentation doesn't support a more specific option: of central nervous system (R94.0), of peripheral nervous system and special senses (R94.1), pulmonary function studies (R94.2), cardiovascular function studies (R94.3), kidney function studies (R94.4), liver function studies (R94.5), thyroid function studies (R94.6) and other endocrine function studies (R94.7).
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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
