About T22.352A

T22.352A is the ICD-10-CM diagnosis code for burn of third degree of left shoulder, initial encounter. It belongs to category T22 (burn and corrosion of shoulder and upper limb, except 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 "A" means initial encounter: use it while the patient is receiving active treatment for the condition.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 927 (Extensive Burns or Full Thickness Burns with MV >96 Hours with Skin Graft, relative weight 27.846), DRG 933 (Extensive Burns or Full Thickness Burns with MV >96 Hours without Skin Graft, relative weight 3.5048), DRG 928 (Full Thickness Burn with Skin Graft or Inhalation Injury with CC/MCC, relative weight 7.6477), DRG 929 (Full Thickness Burn with Skin Graft or Inhalation Injury without CC/MCC, relative weight 3.0193) and DRG 934 (Full Thickness Burn without Skin Graft or Inhalation Injury, relative weight 1.9895), in MDC 22 (Burns), 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 943.35 (full-thickness skin loss [third degree, not otherwise specified] of shoulder), 943.45 (deep necrosis of underlying tissues [deep third degree] without mention of loss of a body part, of shoulder) and 943.55 (deep necrosis of underlying tissues [deep third degree] with loss of a body part, of shoulder).
