V60.5XXD vs V66

V60.5XXD (Driver of heavy transport vehicle injured in collision with pedestrian or animal in traffic accident, subsequent encounter) compared with V66 (Occupant of heavy transport vehicle injured in collision with other nonmotor vehicle), from the official CMS tabular data.

Summary

These codes should not be reported together because V60.5XXD’s tabular entry lists V66 under Excludes1.

Official rule

What is different?

The conditions named and billing status.V60.5XXD is “Driver of heavy transport vehicle injured in collision with pedestrian or animal in traffic accident, subsequent encounter”; V66 is “Occupant of heavy transport vehicle injured in collision with other nonmotor vehicle”. V66 is a non-billable header; V60.5XXD is billable.

Registry fact

Can these codes be reported together?

No.V60.5XXD’s entry carries an Excludes1 note covering V66: “heavy transport vehicle collision with animal-drawn vehicle or animal being ridden (V66.-)”. Both may be reported only when the documentation shows the two conditions are unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes1 relationship?

Yes.V60.5XXD’s tabular entry: “heavy transport vehicle collision with animal-drawn vehicle or animal being ridden (V66.-)”. The note covers V66.

Official ruleGuide: Excludes1 vs Excludes2

Is there an Excludes2 relationship?

None.Neither entry carries an Excludes2 note that names the other code.

Official rule

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.V66 is a non-billable header, but V60.5XXD 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.

What we found

No — do not report together.V60.5XXD carries an Excludes1 note covering V66: “heavy transport vehicle collision with animal-drawn vehicle or animal being ridden (V66.-)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

What to review

Report one of the two. Both may be reported only when the documentation shows the two conditions are unrelated to each other.

Why it matters

An Excludes1 note means the two conditions cannot occur together, so the pair should not be reported for the same encounter. The sole exception is when the conditions are documented as unrelated to each other.

Official guidance behind these answers

Section I.A.12.a — Excludes1 · applies to: Excludes1
A type 1 Excludes note is a pure excludes note. It means “NOT CODED HERE!” An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition. An exception to the Excludes1 definition is the circumstance when the two conditions are unrelated to each other. If it is not clear whether the two conditions involving an Excludes1 note are related or not, query the provider. For example, code F45.8, Other somatoform disorders, has an Excludes1 note for "sleep related teeth grinding (G47.63)," because "teeth grinding" is an inclusion term under F45.8. Only one of these two codes should be assigned for teeth grinding. However psychogenic dysmenorrhea is also an inclusion term under F45.8, and a patient could have both this condition and sleep related teeth grinding. In this case, the two conditions are clearly unrelated to each other, and so it would be appropriate to report F45.8 and G47.63 together.
