About S37.899A

S37.899A is the ICD-10-CM diagnosis code for unspecified injury of other urinary and pelvic organ, initial encounter. It belongs to category S37 (injury of urinary and pelvic organs), block S30-S39 (injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals) 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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544), DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129), DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041) and 3 more, in MDC 12 (Diseases and Disorders of the Male Reproductive System), MDC 13 (Diseases and Disorders of the Female Reproductive System) 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 867.6 (injury to other specified pelvic organs, without mention of open wound into cavity).
