2026 ICD-10-CM Diagnosis Code T62.2X1SToxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela
T62.2X1S is a billable ICD-10-CM diagnosis code for toxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 922 through 923. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Poisoning/toxic effect/adverse effects/underdosing, sequela.

Clinical InformationClinical
Chelidonium majus
a plant species of the family papaveraceae. the common name greater celandine is similar to lesser celandine (ficaria verna), and celandine poppy (stylophorum diphyllum). it has been used in folk medicine and its latex contains biologically active compounds including benzophenanthridines alkaloids (e.g., chelerythrine).Colchicum
a genus of poisonous, liliaceous plants. the roots (corms) of colchicum autumnale, the fall crocus or meadow saffron, yield colchicine, which is used as a biochemical tool and to treat gout. other members of this genus yield saffron dye, flavoring agents, and aromatics.Cytisus
a plant genus of the family fabaceae that is sometimes called broom because of the shape of the plant. members produce sparteine.Laburnum
a plant genus of the family fabaceae named after the drooping clusters of flowers.Delphinium
a plant genus of the family ranunculaceae. members contain aconitine and other diterpenoid alkaloids.Equisetum
the only living genus of the order equisetales, class equisetopsida (sphenopsida), division equisetophyta (sphenophyta); distantly related to ferns. it grows in moist places. the hollow, jointed, ridged stems contain silicates.Cicuta
a plant genus of the family apiaceae. it is a source of cicutoxin.Conium
a plant genus of the family apiaceae that is a source of coniine.Hemlock
any of several poisonous plants, commonly called poison hemlock, of the cicuta or conium genus. the hemlock tree (tsuga) is completely unrelated being a coniferous tree of the pine family.Tsuga
a plant genus in the family pinaceae, order pinales, class pinopsida, division coniferophyta. they are coniferous evergreen trees and should not be confused with hemlock plants (cicuta and conium).Jatropha
a plant genus of the family euphorbiaceae. members contain jatrophone and other diterpenes.Lobelia
a plant genus of the family campanulaceae used medicinally and is a source of lobeline.Melia azedarach
a plant species of the genus melia, family meliaceae, which is toxic to insects. the name is very similar to melia azadirachta (azadirachta).Prunus
a plant genus in the family rosaceae, order rosales, subclass rosidae. it is best known as a source of edible fruits such as apricot, plum, peach, cherry, and almond.Prunus africana
a plant species in the family rosaceae. the bark extract known as pygeum is an ingredient in folk remedies.Prunus armeniaca
a plant species in the family rosaceae. it is the source of apricot fruit.Prunus avium
a plant species in the family rosaceae. it is the source of the sweet cherry fruit.Prunus domestica
a plant species in the family rosaceae. it is a tree that produces fruits called plums.Prunus dulcis
a plant species in the family rosaceae, genus prunus which produces edible seeds called almonds.Prunus persica
a plant species in the family rosaceae. it is a tree that produces peach fruit.Pulsatilla
a plant genus of the family ranunculaceae. members contain cernuosides and other oleanane and hederagenin saponins.Ranunculus
a plant genus of the family ranunculaceae that contains protoanemonin, anemonin, and ranunculin.Ricinus communis
a species in the family euphorbiaceae that is the source of castor oil.Solanine
a mixture of alpha-chaconine and alpha-solanine, found in solanaceae plants.Veratrum
a plant genus of the family melanthiaceae with roots that contain veratrum alkaloids used as emetics, parasiticides, antihypertensives. the common name black hellebore is used for both veratrum nigrum and helleborus niger.Veratrum Alkaloids
alkaloids with powerful hypotensive effects isolated from american or european hellebore (veratrum viride ait. liliaceae and veratrum album l. liliaceae). they increase cholinergic and decrease adrenergic tone with appropriate side effects and at higher doses depress respiration and produce cardiac arrhythmias; only the ester alkaloids have been used as hypotensive agents in specific instances. they have been generally replaced by drugs with fewer adverse effects.

Code HistoryHistory
Questions About T62.2X1SOverview
Is T62.2X1S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report toxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character S in T62.2X1S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the toxic effect of other ingested (parts of) plant(s), accidental (unintentional) itself has resolved, not the original event.
What MS-DRG does T62.2X1S group to?
When toxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 922, 923, with relative weights from 1.0177 to 1.7494 depending on complications. Higher weights mean higher Medicare reimbursement.
Is T62.2X1S exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for toxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela on inpatient claims.
What is the ICD-9 equivalent of T62.2X1S?
Under the General Equivalence Mappings, toxic effect of other ingested (parts of) plant(s), accidental (unintentional), sequela converts to ICD-9-CM 909.1 (late eff nonmed substanc) and E929.2 (late eff acc poisoning). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
