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

Coding at a Glance

Tabular directives
2 inclusion terms

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 729 — OTHER MALE REPRODUCTIVE SYSTEM DIAGNOSES WITH CC/MCC (MDC 12)
  • MS-DRG 730 — OTHER MALE REPRODUCTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC (MDC 12)

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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name N48.6 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 11 Excludes2 notes: R10 — Abdominal and pelvic pain (via N48.-), R10-R19 — Symptoms and signs involving the digestive system and abdomen (R10-R19) (via N48.-), R11 — Nausea and vomiting (via N48.-), R12 — Heartburn (via N48.-), R13 — Aphagia and dysphagia (via N48.-), R14 — Flatulence and related conditions (via N48.-), R15 — Fecal incontinence (via N48.-), R16 — Hepatomegaly and splenomegaly, not elsewhere classified (via N48.-), R17 — Unspecified jaundice (via N48.-), R18 — Ascites (via N48.-), R19 — Other symptoms and signs involving the digestive system and abdomen (via N48.-).

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

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 2 MS-DRGs: DRG 729 (MDC 12), DRG 730 (MDC 12).

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