About T23.652S
T23.652S is the ICD-10-CM diagnosis code for corrosion of second degree of left palm, sequela. It belongs to category T23 (burn and corrosion of wrist and hand), block T20-T25 (burns and corrosions of external body surface, specified by site) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "S" means sequela: use it for complications or conditions that arise as a direct result of the original condition.
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 604 (Trauma to the Skin, Subcutaneous Tissue and Breast with MCC, relative weight 1.453) and DRG 605 (Trauma to the Skin, Subcutaneous Tissue and Breast without MCC, relative weight 0.9079), 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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
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 906.6 (late effect of burn of wrist and hand).
