Q55.22 ICD-10-CM Code: Retractile testis
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Coding at a Glance
- Tabular directives
- 4 Excludes1
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)
- MS-DRG 795 — NORMAL NEWBORN (MDC 15)
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.
Coding instructions
Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for Q55.22 in the official ICD-10-CM tabular list, quoted as published.
Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025
Notes without a marker are published on Q55.22 itself; “inherited from” names the category or block whose note applies here.
Excludes1 — Not Coded Here
Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
- congenital hydrocele (P83.5) inherited from Q55Compare Q55.22 vs P83.5 →
- hypospadias (Q54.-) inherited from Q55Compare Q55.22 vs Q54 →
- androgen insensitivity syndrome (E34.5-) inherited from Q50-Q56Compare Q55.22 vs E34.5 →
- syndromes associated with anomalies in the number and form of chromosomes (Q90-Q99) inherited from Q50-Q56Compare Q55.22 vs Q90 →
Coder workflow for Q55.22
MedCoder structured workflow — derived from this code’s own official record
Before you code Q55.22
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with Q55.22. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).
Choose the right path
- Does the documentation support a condition named in Q55.22’s Excludes1 note?
Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
No → Continue.
Consider Q55.22. Then confirm the code is valid for the date of service in the Verify section.
Documentation check
- The provider’s diagnostic statement
- Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).
Official instructions as workflow
Excludes1 — check before selecting Q55.22(4 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with Q55.22: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.
See the official tabular notes · Guidelines I.A.12.a
Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition Q55.22 describes and a condition named in its Excludes1 note are documented for the same encounter.
Coding question: Can both codes be reported?
Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.
Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).
Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

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 3 MS-DRGs: DRG 729 (MDC 12), DRG 730 (MDC 12), DRG 795 (MDC 15).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
