R87.622 ICD-10-CM Code: Low grade squamous intraepithelial lesion on cytologic smear of vagina (LGSIL)

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

Coding at a Glance

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 742 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITH CC/MCC (MDC 13)
  • MS-DRG 743 — UTERINE AND ADNEXA PROCEDURES FOR NON-MALIGNANCY WITHOUT CC/MCC (MDC 13)
  • MS-DRG 760 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITH CC/MCC (MDC 13)
  • MS-DRG 761 — MENSTRUAL AND OTHER FEMALE REPRODUCTIVE SYSTEM DISORDERS WITHOUT CC/MCC (MDC 13)

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 R87.622 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 R87.622 itself; “inherited from” names the category or block whose note applies here.

Includes

Conditions the official ICD-10-CM tabular list includes under this code.

  • abnormal findings in secretion and smears from cervix uteri
  • abnormal findings in secretion and smears from vagina
  • abnormal findings in secretion and smears from vulva

Source: inherited from R87

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).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Use Additional Code

Supplementary codes the tabular list directs you to add.

  • Use additional code to identify acquired absence of uterus and cervix, if applicable (Z90.71-)

Coder workflow for R87.622

MedCoder structured workflow — derived from this code’s own official record

Before you code R87.622

  1. Check whether an established diagnosis that explains this sign or symptom is documented. If one is, review whether the documented diagnosis changes the coding pathway: a symptom that is integral to a confirmed diagnosis is not reported separately, while one not routinely associated with it may be. Signs and symptoms are reported when no definitive diagnosis is established (Guidelines I.B.4, I.B.5, I.B.6, I.C.18.b).

    Guide: Symptom code vs confirmed diagnosis →

  2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with R87.622. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Is an established diagnosis that explains this sign or symptom documented?
    Yes → Review whether the documented diagnosis changes the coding pathway: a symptom integral to it is not reported separately.
    No → Continue — the sign or symptom code stands when no definitive diagnosis is established.
  2. Does the documentation support a condition named in R87.622’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.

    ReviewR87.61, R87.69, D07.2, N89, O28

Consider R87.622. Then work the Use Additional Code note, and 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).
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.

Official instructions as workflow

  • Excludes1 — check before selecting R87.622(10 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with R87.622: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareR87.61, R87.69, D07.2, N89, O28

    See the official tabular notes · Guidelines I.A.12.a

  • Excludes2 — not part of R87.622(5 notes)

    Coding workflow: The conditions named in this note are not included in R87.622. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareR87.811, R87.821, R97

    See the official tabular notes · Guidelines I.A.12.b

  • Use Additional Code — after identifying R87.622(1 note)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with R87.622 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: The sign or symptom is documented, and the same record establishes a diagnosis that routinely includes it.

Coding question: Is R87.622 reported in addition to the diagnosis?

Path: Review the documented diagnosis and whether the classification treats this finding as integral to it.

Reason: Signs and symptoms integral to a confirmed diagnosis are not coded separately; those not routinely associated with it may be reported when present (Guidelines I.B.5, I.B.6, I.C.18.b).

Documentation: Both the condition R87.622 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).

ReviewR87.61, R87.69, D07.2, N89, O28

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with R87.622?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

  2. 10 Excludes1 entries — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
  3. 5 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name R87.622 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 2 Excludes1 notes across 2 chapters: N89 — Other noninflammatory disorders of vagina (via R87.62.-), R87.61 — Abnormal cytological findings in specimens from cervix uteri (via R87.62.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

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 4 MS-DRGs: DRG 742 (MDC 13), DRG 743 (MDC 13), DRG 760 (MDC 13), DRG 761 (MDC 13).

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