NOTE: This patient previously suffered burns to the right palm and is now treated for painful scarring due to the burns. The painful scarring is a late effect of
the previous burns, and according to ICD-10-CM coding guidelines the coding of late effects generally requires two codes sequenced in the following order: The
condition or nature of the late effect is sequenced first. The late effect code is sequenced second. Thus, the code for painful scarring is sequenced first followed
by codes for second-degree burn of right palm (with seventh-character “S” that indicates treatment for a sequela of the original condition) and extent of burn.

Poisonings, Adverse Effects, and Underdosing
NOTE: Use the Table of Drugs and Chemicals to begin the process of locating each code.

Accidental lead poisoning (child discovered eating paint chips) (initial encounter)
Anaphylactic shock due to allergic reaction to penicillin (initial encounter)
T56.0x1A
T36.0x5A,
T88.6xxA
NOTE: The note below ICD-10-CM code T88.6 states Code First: to identify drug T36-T50 with fifth or sixth character 5. Thus, code T88.6xxA is reported
as a secondary code.
203.

205.
Theophylline toxicity (initial encounter)
Carbon monoxide poisoning from car exhaust (suicide attempt) (initial encounter)
Hypertension due to underdosing of Aldomet occurred (initial encounter)
T48.6x5A
T58.02xA
I10, T46.5x6A
NOTE: According to ICD-10-CM coding guidelines, underdosing refers to taking less of a medication than is prescribed by a provider or a manufacturer’s
instruction. For underdosing, assign the code from categories T36-T50 (fifth or sixth character “6”). Codes for underdosing should never be assigned as
­principal or first-listed codes. If a patient has a relapse or exacerbation of the medical condition for which the drug is prescribed because of the reduction in
dose, then the medical condition itself should be coded. Noncompliance (Z91.12-Z91.13) or complications of care (Y63.61, Y63.8-Y63.9) codes are to be used
with an underdosing code to indicate intent, if known. Thus, the code for hypertension is sequenced first, followed by the underdosing of Aldomet code
(with seventh-character “A” to indicate initial encounter).
External Causes of Morbidity
NOTE: Use the ICD-10-CM Index to Diseases and Injuries to begin the process of locating the condition (e.g., abrasion). Then, use the ICD-10-CM Index to
External Causes to begin the process of locating each code.

Encounter for removal of cast from healed pathologic fracture of right ankle
Z20.1
Z80.0
Z09, Z52.4
M84.471D
NOTE: Do not report code Z47.89 (in addition to or instead of the fracture code) because ICD-10-CM coding guidelines state that the aftercare Z codes
should not be used for aftercare for injuries. For aftercare of an injury, assign the acute injury code with the appropriate 7th character (for subsequent encounter). Thus, code M84.471 is reported with seventh-character “D” to indicate an subsequent encounter (that involved removal of the cast).

Admitted as bone marrow donor
Encounter for chemotherapy for patient with Hodgkin lymphoma

Encounter for renal dialysis in patient with end-stage renal failure
Z52.3
Z51.11, C81.90
Z45.018
Z43.0
N18.6, Z99.2
NOTE: Do not report code Z49.31, which is an encounter for adequacy testing for hemodialysis. The encounter for renal dialysis is reported with code N18.6,
which also states use additional code to identify dialysis status Z99.2 when classifying end-stage renal disease. Because this patient’s encounter was for renal
dialysis, code N18.6 is reported first (to classify the reason for encounter) and code Z99.2 is reported second (to classify the patient’s dialysis status).
