O60.13X0 ICD-10-CM Code: Preterm labor second trimester with preterm delivery third trimester, not applicable or unspecified
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.
- MS-DRG 998 — PRINCIPAL DIAGNOSIS INVALID AS DISCHARGE DIAGNOSIS (MDC 14)
A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Verify Before Coding
- Age-restricted: the Medicare Code Editor lists this as a maternity (age 9-64) diagnosis; other ages are presumed incorrect.
- MCC as a secondary diagnosis (FY2026). Can raise the stay's MS-DRG severity tier.
From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim.

Potential MS-DRG Relationships (FY2026)
MCC — Major Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 277 clinically related codes on its CMS exclusion list.
Named in the grouper logic of 1 MS-DRG: DRG 998 (MDC 14).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Acts as MCC — raises the severity of other admissions. CMS groups these diagnoses into one MS-DRG principal-diagnosis exclusion process — a CC/MCC on this list never raises severity when the principal diagnosis is also on it.

Frequently Asked Questions (FAQ) & Clinical Guidance
Does O60.13X0 require a 7th character?
Yes. One of the following 7th characters is to be assigned to each code under subcategory O60.1. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from subcategory O60.1 that has a 7th character of 1 through 9..
