S01.441APuncture wound with foreign body of right cheek and temporomandibular area, initial encounter

S01.441A is the ICD-10-CM diagnosis code for puncture wound with foreign body of right cheek and temporomandibular area, initial encounter. It belongs to category S01 (open wound of head), block S00-S09 (injuries to the head) 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.

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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 604 (Trauma to the Skin, Subcutaneous Tissue and Breast with MCC, relative weight 1.453), DRG 605 (Trauma to the Skin, Subcutaneous Tissue and Breast without MCC, relative weight 0.9079), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363) and 2 more, in Pre-MDC, MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 24 (Multiple Significant Trauma), 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 873.51 (open wound of cheek, complicated) and 873.54 (open wound of jaw, complicated).
