About coding thermography
The ICD-10-CM code for thermography is R93.89 (Abnormal findings on diagnostic imaging of other specified body structures). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R93.89.
Within R93.8, choose R93.89 (findings on diagnostic imaging of other specified body structures) only when documentation doesn't support a more specific option: radiologic findings on diagnostic imaging of testis (R93.81).
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 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
