ICDICD--1010--CM CM DraftDraft Official Official Guidelines for Coding and Guidelines for Coding and

Reporting Reporting Reporting Reporting

ICD-10-CM Guidelines• Used as a companion document to the

official version of ICD-10-CM

• Approved by the Cooperating Parties

– CMS, NCHS, AHIMA, AHA

• Developed to accompany and complement the official conventions and instructions provided within ICD-10-CM itself

• Instructions and conventions of the classification take precedence over guidelines

ICD-10-CM Guidelines

• No changes to many areas of the guidelines

• I.A.4 – Placeholder character

– Placeholder “x”– Placeholder “x”

• I.A.5 – 7th Characters

– Applicable 7th characters

• I.A.12.a – Excludes1 – NOT coded here

• I.A.12.b – Excludes2 – Not included here

ICD-10-CM Guidelines• I.B.16 – Documentation of Complications

of Care

– Must be a cause-and-effect relationship

• I.C.1.d.2.a – Septic Shock (additional wording)wording)

– . . . the code for septic shock cannot be

assigned as a principal diagnosis

• I.C.1.d.5 – Sepsis due to a postprocedural infection

– Documentation of a causal relationship

ICD-10-CM Guidelines

• I.C.2.c.1 - Anemia associated with malignancy

– Malignancy sequenced as principal/first-listed

• I.C.2.c.2 – Anemia associated with • I.C.2.c.2 – Anemia associated with chemotherapy, Immunotherapy and radiation therapy

– Anemia sequenced first

– Followed by codes for neoplasm and the

adverse effect

ICD-10-CM Guidelines• I.C.7.a – Glaucoma

– New guidelines associated with the new

Glaucoma codes

• I.C.9.e.4 – Subsequent acute myocardial infarctioninfarction

– I22, Subsequent ST elevation (STEMI) and

non ST elevation (NSTEMI) myocardial

infarction, is to be used when a patient who

has suffered an AMI has a new AMI within the

4 week time frame of the initial AMI

– Sequencing depends of circumstances of

admission

ICD-10-CM Guidelines• I.C.15.a.3 – Final character for trimester

– Final character indicating the trimester of

pregnancy

• I.C.15.a.6 – 7th character for fetus identificationidentification

– 7th character to be assigned for certain

categories to identify the fetus for which the

complication code applies

– O31, O32, O33.3-O33.6, O35, O36, O40, O41,

O60.1, O60.2, O64, and O69

ICD-10-CM Guidelines

• I.C.18.e – Coma scale

– Assign code R40.24, Glasgow coma scale,

total score, when only the total score is

documented in the medical record and not the documented in the medical record and not the

individual score(s).

• I.C.19.e.5.a – Adverse effect

– Nature of the adverse effect followed by the

appropriate code for the adverse effect of the

drug

ICD-10-CM GuidelinesA patient has liver metastasis due to

adenocarcinoma of the rectum which was

resected two years ago. The patient has been

receiving radiotherapy to the liver with some

relief of pain. The patient is being admitted at

this time for management of severe anemia due this time for management of severe anemia due

to the malignancy. The principal diagnosis listed

on this admission is:

a. Liver metastasis

b. Adenocarcinoma of the rectum

c. Anemia

d. Admission for radiotherapy

ICD-10-CM GuidelinesAnswer: A liver metastasis

Rationale: When an admission or encounter is

for the management of an anemia associated

with the malignancy, and the treatment is only

for anemia, the appropriate code for the for anemia, the appropriate code for the

malignancy is sequenced as the principal or first

listed diagnosis followed by the appropriate code

for the anemia, (such as D63.0, Anemia in

neoplastic disease) (ICD-10-CM coding

guideline I.C.2.c.1). In addition, in the Tabular,

the note under D63.0 states to code first

neoplasm (C00-D49).

ICD-10-CM GuidelinesTrue or False? A fracture not described as

“displaced” or “not displaced” by default

should be coded as “not displaced.”

Answer: B False

Rationale: A fracture not indicated whether Rationale: A fracture not indicated whether

displaced or not displaced should be coded

to displaced (ICD-10-CM coding guideline

I.C.19.c). This information is also available in

notes in the Tabular (see category S52). A

fracture not described as open or closed is

coded to the default of closed.

ICD-10-CM Guidelines

In ICD-10-CM diabetes mellitus codes include:

a. The type of diabetes mellitus

b. The body system affectedb. The body system affected

c. The complication affecting that body system

d. All of the above

ICD-10-CM Guidelines

Answer: D all of the above

Rationale: The diabetes mellitus codes are combination codes that include the are combination codes that include the type of diabetes mellitus, the body system affected and the complications affecting that body system (ICD-10-CM coding guideline I.C.4.a).

ICD-10-CM GuidelinesTrue or False? A noncompliance code or

complication of care code is to be used with an

underdosing code to indicate intent.

Answer: A True

Rationale: Underdosing refers to taking less of a Rationale: Underdosing refers to taking less of a

medication than is prescribed by a provider or a

manufacturer’s instruction. Noncompliance (Z91.12-, Z91.13-) or complication of care (Y63.8-Y63.9) codes are to be used with an underdosing code to indicate intent, if known (ICD-10-CM coding guideline I.C.19.e.5.c). Codes for underdosing should never be assigned as principal or first-listed codes.

ICD-10-CM GuidelinesTrue or False? When coding severe sepsis a

minimum of three codes is required.

Answer: B False

Rationale: The coding of severe sepsis requires a

minimum of two codes: first a code for the underlying minimum of two codes: first a code for the underlying

systemic infection, followed by a code from subcategory

R65.2, Severe sepsis. If the causal organism is not

documented, assign code A41.9, Sepsis, unspecified

organism, for the infection (ICD-10-CM coding guideline

I.C.1.d.1.b). Additional codes for the other acute organ

dysfunctions should also be assigned. This condition

usually will result in a total of three codes, except in the

case of combination codes, such as severe sepsis with

septic shock.
