T20 vs T83.590D

T20 (Burn and corrosion of head, face, and neck) compared with T83.590D (Infection and inflammatory reaction due to implanted urinary neurostimulation device, subsequent encounter), from the official CMS tabular data.

Summary

These codes can be reported together when both conditions are documented, because T83.590D lists T20 under Excludes2, which marks them as distinct conditions.

Official rule
What is different?

The conditions named and billing status.T20 is “Burn and corrosion of head, face, and neck”; T83.590D is “Infection and inflammatory reaction due to implanted urinary neurostimulation device, subsequent encounter”. T20 is a non-billable header; T83.590D is billable.

Registry fact

Can these codes be reported together?

Yes, when both are documented.T83.590D lists T20 under Excludes2: “burns and corrosions from local applications and irradiation (T20-T32)”. Excludes2 marks distinct conditions that may both be reported when both are documented.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes1 relationship?

None.Neither entry carries an Excludes1 note that names the other code.

Official rule

Is there an Excludes2 relationship?

Yes.T83.590D’s tabular entry: “burns and corrosions from local applications and irradiation (T20-T32)”. The note covers T20.

Official ruleGuide: Excludes1 vs Excludes2

Is one more specific?

Not comparable.The codes sit in different categories; specificity is only comparable within one category.

Is one a parent or header code?

One is a header.T20 is a non-billable header, but T83.590D is not one of its subdivisions.

Registry fact

Are there sequencing instructions?

None.Neither entry carries a Code First or Use Additional Code note that names the other.

Official rule

Are there other coding relationships?

None found.No laterality, encounter-phase, Table of Neoplasms, Table of Drugs and Chemicals, or history-versus-active-disease relationship links these codes.

MedCoder-derived

Official rule: a tabular instructional note or a section of the ICD-10-CM Official Guidelines, quoted as published. Registry fact: the codes’ own published attributes (titles, billable status, position in the hierarchy, code set). MedCoder-derived: a reading MedCoder computes from those facts; it is not itself a rule. How to read the labels

What we found

Yes, when both are documented.T83.590D carries an Excludes2 note covering T20: “burns and corrosions from local applications and irradiation (T20-T32)”

Excludes2 marks distinct conditions — both may be reported when both are documented.

What to review

Report both only when the documentation supports both conditions; otherwise report the one documented.

Why it matters

An Excludes2 note means the excluded condition is not part of the code above it, but a patient can have both. Report both when both are documented.

CMS ICD-10-CM tabular instructional notes

Official guidance behind these answers

  • Section I.A.12.b — Excludes2 · applies to: Excludes2

    A type 2 Excludes note represents “Not included here.” An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
