T53.6X1 — Toxic effect of other halogen derivatives of aliphatic hydrocarbons, accidental (unintentional)
Is T53.6X1 billable?
No — T53.6X1 is a non-billable header code. T53.6X1 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 3 billable codes beneath T53.6X1.

Inclusion terms
Alternative wording in documentation that is classified to T53.6X1.
- Toxic effects of other halogen derivatives of aliphatic hydrocarbons NOS
Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T53.6X1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- contact with and (suspected) exposure to toxic substances (Z77.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T53.6X1 to fully describe the condition. T53.6X1 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T51-T65
Report an additional code alongside T53.6X1 to fully describe the condition. T53.6X1 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T53.6X1, but a patient may have both at the same time. When documentation supports it, T53.6X1 and the excluded code may both be reported.

How long has T53.6X1 existed?
T53.6X1 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
