Toxic effect of venom of brown recluse spider, intentional self-harm, subsequent encounter
This code does not map to a risk-adjusting HCC in the loaded models.
Coding notes
Excludes 1 never coded together · Excludes 2 may co-exist
bite or touch of venomous animal pricked or stuck by thorn or leaf
The appropriate 7th character is to be added to each code from category T63
| Character | Meaning |

| A | initial encounter |
| D | subsequent encounter |
| S | sequela |
contact with and (suspected) exposure to toxic substances (Z77.-)
code(s): for all associated manifestations of toxic effect, such as: respiratory conditions due to external agents (J60-J70) personal history of foreign body fully removed (Z87.821) to identify any retained foreign body, if applicable (Z18.-)
When no intent is indicated code to accidental. Undetermined intent is only for use when there is specific documentation in the record that the intent of the toxic effect cannot be determined.
code to identify any retained foreign body, if applicable (Z18.-)
Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes. (T07-T88) Injury, poisoning and certain other consequences of external causes (T07-T88) (T20-T32) Burns and corrosions (T20-T32) Includes: burns (thermal) from electrical heating appliances burns (thermal) from electricity burns (thermal) from flame burns (thermal) from friction burns (thermal) from hot air and hot gases burns (thermal) from hot objects burns (thermal) from lightning burns (thermal) from radiation chemical burn [corrosion] (external) (internal) scalds Excludes2: erythema [dermatitis] ab igne (L59.0) radiation-related disorders of the skin and subcutaneous tissue (L55-L59) sunburn (L55.-)

The column is chosen by the documentation, not by the coder. Intent follows the documented circumstance; adverse effect requires that the drug was correctly prescribed and properly administered (Guideline I.C.19.e). Coefficients are Community, Non-Dual, Aged under CMS-HCC V28 PY2027. How these figures were derived.
