N70.11 ICD-10-CM Code: Chronic salpingitis
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 757 — INFECTIONS, FEMALE REPRODUCTIVE SYSTEM WITH MCC (MDC 13)
- MS-DRG 758 — INFECTIONS, FEMALE REPRODUCTIVE SYSTEM WITH CC (MDC 13)
- MS-DRG 759 — INFECTIONS, FEMALE REPRODUCTIVE SYSTEM 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 N70.11 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 N70.11 itself; “inherited from” names the category or block whose note applies here.
This page already reflects the FY2027 tabular note taking effect October 1, 2026.
Includes
Conditions the official ICD-10-CM tabular list includes under this code.
- abscess (of) fallopian tube
- abscess (of) ovary
- pyosalpinx
- salpingo-oophoritis
- tubo-ovarian abscess
- tubo-ovarian inflammatory disease
Source: inherited from N70
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).

Coder workflow for N70.11
MedCoder structured workflow — derived from this code’s own official record
Before you code N70.11
- Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with N70.11. 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 N70.11’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 N70.11. Then work the Use Additional Code note and review the Code Also 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).
- Acuity
- Acute or chronic as documented; when both are documented and separate codes exist, both are reported with the acute code first (Guidelines I.B.8).
- 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 N70.11(5 notes)
Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with N70.11: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.
CompareA54.24, A18.17, O08.0, O23, O75.3, O85
See the official tabular notes · Guidelines I.A.12.a
Use Additional Code — after identifying N70.11(1 note)
Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with N70.11 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.
See the official tabular notes · Guidelines I.A.13
Code Also — related condition(1 note)
Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.
ReviewK6A.0

Coding decision scenarios
Pattern scenarios for this code’s structure — decision rules, not clinical cases
Documentation: Both the condition N70.11 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).
Documentation: A condition the Use Additional Code note names is documented.
Coding question: Is a second code reported with N70.11?
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).
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 (5)
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.

- Salpingitis (catarrhal) (fallopian tube) (nodular) (pseudofollicular) (purulent) (septic), chronic
- Salpingitis (catarrhal) (fallopian tube) (nodular) (pseudofollicular) (purulent) (septic), follicularis
- Salpingitis (catarrhal) (fallopian tube) (nodular) (pseudofollicular) (purulent) (septic), interstitial, chronic

Decision Points
The directives on this code's own record, as a pre-claim checklist.
- 1 Use Additional Code instruction — report the named additional code(s) when the documentation supports them. See the Use Additional Code notes
- 1 Code Also note — a second code may apply; the guidelines leave its sequencing to the circumstances of the encounter. See the Code Also notes
- 5 Excludes1 entries — codes named there are generally not reported together with this code (Guidelines I.A.12.a). See the Excludes1 notes
Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Referenced by 1 Excludes2 note: N83 — Noninflammatory disorders of ovary, fallopian tube and broad ligament (via N70.1.-).
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 5 MS-DRGs: DRG 742 (MDC 13), DRG 743 (MDC 13), DRG 757 (MDC 13), DRG 758 (MDC 13), DRG 759 (MDC 13).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
