Inpatient Coding Guidelines with Complete Solutions

SELECTION OF PRINCIPAL DIAGNOSIS -

ANSWER -The principal diagnosis is

defined in the Uniform Hospital Discharge Data

Set (UHDDS) as "that condition established after

study to be chiefly responsible for occasioning

the admission of the patient to the hospital for

care."

CODES FOR SYMPTOMS,SIGNS, AND ILL-

DEFINED CONDITIONS - ANSWER -

Codes for symptoms,signs and ill-defined

conditions from Chapter 16 are not to be used as

a principal diagnosis when a related definitive

diagnosis has been established.

TWO -OR- MORE INTERRELATED

CONDITIONS, EACH POTENTIALLY MEETING

THE DEFINITION FOR PRINCIPAL DIAGNOSIS

- ANSWER -When there are two or more

interrelated conditions (such as a disease in the

same ICD-9chapter manifestations

characteristically associated with a certain

disease) potentially meeting the definition of

principal diagnosis, either condition may be

sequenced first, unless the circumstances of the

admission, the therapy provided, the Tabular

List, or the Alphabetic Index indicate otherwise.

TWO OR MORE DIAGNOSIS THAT EQUALLY

MEET THE DEFINITION FOR PRINCIPAL

DIAGNOSIS. - ANSWER -In the unusual

instance when two or more diagnoses equally

meet the criteria for principal diagnosis as

determined by the circumstances of admission,

diagnostic workup and/or therapy provided, and

the Alphabetic Index, Tabular List, or another

coding guideline does not provide sequencing

direction, any one of the diagnoses may be

sequenced first.

COMPARATIVE -OR- CONTRASTING

CONDITIONS. - ANSWER -In those rare

instances when two or more contrasting or

comparative diagnoses are documented as

"either/or" (or similar terminology), they are coded

as if the diagnoses were confirmed and the

diagnoses are sequenced according to the

circumstances of the admission. If no further

determination can be made as to which diagnosis

should be principal, either diagnosis may be

sequenced first.

SYMPTOMS(s) FOLLOWED BY

CONTRASTING/COMPARATIVE DIAGNOSIS. -

ANSWER -When a symptom(s) is followed

by contrasting/comparative diagnoses, the

symptom code is sequenced first. All the

contrasting/comparative diagnoses should be

coded as additional diagnoses.

ORIGINAL TREATMENT PLAN "NOT" CARRIED

OUT. - ANSWER -Sequence as the

principal diagnosis the condition, which after

study occasioned the admission to the hospital,

even though treatment may not have been

carried out due to unforeseen circumstances.

COMPLICATIONS OF SURGERY AND OTHER

MEDICAL CARE. - ANSWER -When the

admission is for treatment of a complication

resulting from surgery or other medical care, the

complication code is sequenced as the principal

diagnosis. If the complication is classified to the

996-999 series and the code lacks the necessary

specificity in describing the complication, an

additional code for the specific complication

should be assigned.

UNCERTAIN DIAGNOSIS - ANSWER -If

the diagnosis documented at the time of

discharge is qualified as "probable", "suspected",

"likely", "questionable", "possible", or "still to be

ruled our", or other similar terms indicating

uncertainty, code the condition as if it existed or

was established. NOTE: This guideline is applicable only to inpatient admissions to short term, acute, long- term care and psychiatric hospitals. ADMISSION FROM OBSERVATION UNIT - ANSWER - 1. Admission Following Medical Observation When a patient is admitted to an observation unit for a medical condition, which either worsens or does not improve, and is subsequently admitted as an inpatient of the same hospital for this same medical condition, the principal diagnosis would be the medical condition which led to the hospital admission.

Admission Following Post-Operative Observation When a patient is admitted to an observation unit to "monitor" a condition (or complication) that develops following outpatient surgery, and then is subsequently admitted as an inpatient of the same hospital, hospitals should apply the Uniform Hospital Discharge Data Set (UHDDS) definition of principal diagnosis as :that condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care." ADMISSION FROM OUTPATIENT SURGERY - ANSWER - When a patient receives surgery in the hospital's outpatient surgery department and is subsequently admitted for continuing inpatient care at the same hospital, the following guidelines should be followed in selecting the principal diagnosis for the impatient admission.

If the reason for the inpatient admission is a complication, assign the complication as the principal diagnosis.
If no complication, or other condition, is documented as the reason for the inpatient admission, assign the reason for the outpatient surgery as the principal diagnosis.
- If the reason for the inpatient admission is another condition unrelated to the surgery, assign the unrelated condition a s the principal diagnosis. REPORTING ADDITIONAL DIAGNOSIS - ANSWER - For reporting purposes the definition for :other diagnoses: is interpreted as additional conditions that affect patient care in terms of requiring: clinical evaluation; or therapeutic treatment; or diagnostic procedures; or extended length of hospital stay. or increased nursing care and/or monitoring. The UHDDS defines "other diagnosis" as "all conditions that coexist at the time of admission, that develop subsequently, or that affect the treatment received an/or the length of stay. Diagnosis that relate to an earlier episode which have no bearing on the current hospital stay are to be excluded." UHDDS definitions apply to inpatients in acute care, short-term, long term care and psychiatric hospital setting. The UHDDS definitions are used by acute care short-term hospitals to report impatient data elements in a standard manner. REPORTING ADDITIONAL DIAGNOSES (PAR.4) - ANSWER - The following guidelines are to be applied in designating :there diagnoses when neither the Alphabetic Index nor the Tabular List in the ICD- 9 - CM provide direction. The listing of the diagnosis in the patient record is the responsibility of the attending provider. A. Previous condition If the provider has included a diagnosis in the
