About T81.41XD

T81.41XD is the ICD-10-CM diagnosis code for infection following a procedure, superficial incisional surgical site, subsequent encounter. It belongs to category T81 (complications of procedures, not elsewhere classified), block T80-T88 (complications of surgical and medical care, not elsewhere classified) 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 "D" means subsequent encounter: use it for encounters after active treatment, while the patient is healing or recovering.

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

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 949 (Aftercare with CC/MCC, relative weight 1.123) and DRG 950 (Aftercare without CC/MCC, relative weight 0.7664), 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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2019, effective October 1, 2018.
