R94.7Abnormal results of other endocrine function studies

R94.7 is the ICD-10-CM diagnosis code for abnormal results of other endocrine function studies. It belongs to category R94 (abnormal results of function studies), block R90-R94 (abnormal findings on diagnostic imaging and in function studies, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R94, choose R94.7 (other endocrine function studies) 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 of other organs and systems (R94.8).

The conditions in its Excludes2 note aren't part of R94.7, but may be coded alongside it if the patient has both: abnormal glucose (R73.0-).

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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), 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 794.6 (nonspecific abnormal results of other endocrine function study).
