Q25.0 ICD-10-CM Code: Patent ductus arteriosus

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Coding at a Glance

Tabular directives
2 inclusion terms
Risk adjustment
RxHCC V08 category 191

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43, Appendix B.

  • MS-DRG 306 — CARDIAC CONGENITAL AND VALVULAR DISORDERS WITH MCC (MDC 05)
  • MS-DRG 307 — CARDIAC CONGENITAL AND VALVULAR DISORDERS WITHOUT MCC (MDC 05)

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.

Code Overview

Patent ductus arteriosus is a billable ICD-10-CM diagnosis code (Q25.0).

MedCoder summary Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.

Indexed Clinical Terms (14)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Verify Before Coding

  • CC 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 in Claim Check.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name Q25.0 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 1 Excludes2 note: P29 — Cardiovascular disorders originating in the perinatal period (via Q25.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Referenced by 3 Code Also instructions across 2 chapters: I27.21 — Secondary pulmonary arterial hypertension (via Q25.-), I27.83 — Eisenmenger's syndrome, Z71.87 — Encounter for pediatric-to-adult transition counseling (via Q25.-).

These codes suggest coding this condition alongside when both are present.

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: CC — 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 6 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 2 MS-DRGs: DRG 306 (MDC 05), DRG 307 (MDC 05).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Related Codes

Same clinical process (MS-DRG)

Acts as CC — 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.

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main terms “Malformation”, “Persistence, persistent”, “Anomaly, anomalous”, …; these codes share that main term but sit in a different category of the Tabular List.

Q23.3 — Congenital mitral insufficiency (mitral, insufficiency), Q23.81 — Bicuspid aortic valve (heart, valve NEC, aortic, bicuspid valve), Q23.82 — Congenital mitral valve cleft leaflet (mitral, cleft), Q23.88 — Other congenital malformations of aortic and mitral valves (aortic, cusp or valve), Q23.9 — Congenital malformation of aortic and mitral valves, unspecified (mitral), Q24.3 — Pulmonary infundibular stenosis (pulmonary, valve, stenosis, subvalvular), Q24.4 — Congenital subaortic stenosis (heart, valve NEC, aortic, stenosis, subaortic), Q24.5 — Malformation of coronary vessels (coronary vessels), Q24.8 — Other specified congenital malformations of heart (pericardium), Q24.9 — Congenital malformation of heart, unspecified (heart), Q26.0 — Congenital stenosis of vena cava (great, vein, vena cava stenosis, congenital), Q26.1 — Persistent left superior vena cava (left, superior vena cava), Q26.2 — Total anomalous pulmonary venous connection (pulmonary, venous connection, total), Q26.3 — Partial anomalous pulmonary venous connection (pulmonary, venous connection, partial), Q26.4 — Anomalous pulmonary venous connection, unspecified (opening, pulmonary veins), Q26.5 — Anomalous portal venous connection (portal vein), Q26.6 — Portal vein-hepatic artery fistula (great, vein, portal vein-hepatic artery fistula), Q26.8 — Other congenital malformations of great veins (venous return), Q26.9 — Congenital malformation of great vein, unspecified (vein, great), Q27.0 — Congenital absence and hypoplasia of umbilical artery (artery NOS, umbilical), +504 more
