Q75.2 ICD-10-CM Code: Hypertelorism
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Coding at a Glance
- Tabular directives
- 9 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 564 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITH MCC (MDC 08)
- MS-DRG 565 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITH CC (MDC 08)
- MS-DRG 566 — OTHER MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE DIAGNOSES WITHOUT CC/MCC (MDC 08)
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 Q75.2 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 Q75.2 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 malformation of face NOS (Q18.-) inherited from Q75Compare Q75.2 vs Q18 →
- congenital malformation syndromes classified to Q87.- inherited from Q75
- dentofacial anomalies including malocclusion
- musculoskeletal deformities of head and face (Q67.0-Q67.4) inherited from Q75Compare Q75.2 vs Q67.0 →
- skull defects associated with congenital anomalies of brain such as:
- anencephaly (Q00.0) inherited from Q75Compare Q75.2 vs Q00.0 →
- encephalocele (Q01.-) inherited from Q75Compare Q75.2 vs Q01 →

- microcephaly (Q02) inherited from Q75Compare Q75.2 vs Q02 →
Coder workflow for Q75.2
MedCoder structured workflow — derived from this code’s own official record
Before you code Q75.2
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with Q75.2. 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 Q75.2’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 Q75.2. 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 Q75.2(9 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with Q75.2: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition Q75.2 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.

Indexed Clinical Terms (1)
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.

Relationships & Classification
MedCoder structured relationships — computed from published CMS and AHRQ datasets
Other codes that name Q75.2 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 3 Excludes1 notes across 3 chapters: H05.3 — Deformity of orbit, M24.3 — Pathological dislocation of joint, not elsewhere classified (via Q75.-), Q18 — Other congenital malformations of face and neck (via Q75.-).
These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.
Referenced by 1 Excludes2 note: M95 — Other acquired deformities of musculoskeletal system and connective tissue (via Q75.-).
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 3 MS-DRGs: DRG 564 (MDC 08), DRG 565 (MDC 08), DRG 566 (MDC 08).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
