N35.814 ICD-10-CM Code: Other anterior urethral stricture, male

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for N35.814 in the official ICD-10-CM tabular list, quoted as published.

Coder workflow for N35.814

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

Before you code N35.814

1. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on N35.814; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

   See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

2. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with N35.814. 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. Does the documentation support a condition named in N35.814’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.

   ReviewN99.1, Q64.3

Consider N35.814. 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).

Anatomical site

At the most specific level the record states; a site the classification separates cannot be assumed from a procedure or a measurement.

Any detail beyond this code’s title

What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

• Excludes1 — check before selecting N35.814(2 notes)

  Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with N35.814: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

  CompareN99.1, Q64.3

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

• Excludes2 — not part of N35.814(3 notes)

  Coding workflow: The conditions named in this note are not included in N35.814. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

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

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.

• Stricture, urethra (organic) (spasmodic), specified cause NEC, male, anterior urethra

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of N35.814 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

• N99.1— Excludes1 conflict (Excludes1 — generally not reported together)

  Not coded here — the tabular list excludes this pair for the same encounter.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of postprocedural urethral stricture moves the case to N99.1; the two are not reported together unless documented as unrelated.

  Full comparison: N35.814 vs N99.1 →

• Q64.3— Excludes1 conflict (Excludes1 — generally not reported together)

  Not coded here — the tabular list excludes this pair for the same encounter.

  Not reported together with this code, except where the two conditions are documented as unrelated.

  What moves you there: Documentation of congenital urethral stricture moves the case to Q64.3; the two are not reported together unless documented as unrelated.

  Full comparison: N35.814 vs Q64.3 →

• N35.819— Specificity relationship (Review)

  Overlapping diagnoses in the same category.

  Overlapping codes in the same category — the documentation decides which is the more specific fit.

  What moves you there: A record that documents no more than “Other urethral stricture, male, unspecified site” takes N35.819; specificity in the record moves it back here.

• O00— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of abortion or ectopic or molar pregnancy adds O00; it is not part of this code and both may be reported when both are documented.

• O07— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

Relationships are read from this code's own official notes, its laterality siblings and its encounter family; the wording of each distinction is MedCoder editorial, and the documentation named in each “what moves you there” line is the official note phrase or sibling title itself.
