About coding breast thermography
The ICD-10-CM code for breast thermography is R92.8 (Other abnormal and inconclusive findings on diagnostic imaging of breast).
Within R92, choose R92.8 (Other abnormal and inconclusive findings on diagnostic imaging of breast) only when documentation doesn't support a more specific option: Mammographic microcalcification found on diagnostic imaging of breast (R92.0), Mammographic calcification found on diagnostic imaging of breast (R92.1), inconclusive mammogram (R92.2) and Mammographic density found on imaging of breast (R92.3).
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 600 (Non-Malignant Breast Disorders with CC/MCC, relative weight 0.9975) and DRG 601 (Non-Malignant Breast Disorders without CC/MCC, relative weight 0.6017), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
