T62.94XS ICD-10-CM Code: Toxic effect of unspecified noxious substance eaten as food, undetermined, sequela

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 922 — OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITH MCC (MDC 21)
  • MS-DRG 923 — OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITHOUT MCC (MDC 21)

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.

Code Overview

Toxic effect of unspecified noxious substance eaten as food, undetermined, sequela is a billable ICD-10-CM diagnosis code (T62.94S).

Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for T62.94XS in the official ICD-10-CM tabular list.

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).

Use Additional Code

Supplementary codes the tabular list directs you to add.

  • Use additional code(s): inherited from T51-T65
  • for all associated manifestations of toxic effect, such as: respiratory conditions due to external agents (J60-J70) inherited from T51-T65
  • personal history of foreign body fully removed (Z87.821) inherited from T51-T65
  • to identify any retained foreign body, if applicable (Z18.-) inherited from T51-T65

Frequently Compared Codes

The official Excludes notes on T62.94XS name these codes. Each comparison page covers when the two can — or must not — be reported together.

MS-DRG Grouper Relationships (FY2026)

Not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity.

Named in the grouper logic of 2 MS-DRGs: DRG 922 (MDC 21), DRG 923 (MDC 21).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
