ICD-10-CM Diagnosis code J14

Pneumonia due to Hemophilus influenzae

Coding Guidelines for J14

J14 is a valid ICD-10-CM diagnosis code meaning 'Pneumonia due to Hemophilus influenzae'.

It is also suitable for:

  • Bronchopneumonia due to H. influenzae

Purely Excluded Conditions

These diag codes should never be used at the same time as J14 because these conditions cannot occur together:

  • congenital pneumonia due to H. influenzae (P23.6)

Must Code Etiology Before Coding J14

Some conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation.

J14 is a manifestation code. For it to be valid, one of the following etiology codes must also be coded first:

  • associated influenza, if applicable (J09.X1, J10.0-, J11.0-)

Two Codes Required to Describe Condition

Two codes may be required to fully describe the patient's condition, but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the patient encounter.

  • associated abscess, if applicable (J85.1)

Complications & Comorbid Conditions (CC/MCC) Rules for J14

When J14 is used as a secondary diagnostic code, the patient's visit may be considered to have Complications & Comorbid Conditions (CC) or Major Complications & Comorbid Conditions (MCC).

Exclusions apply. When the primary diagnostic code is is in the exclusion list, the patient visit CC/MCC does not qualify for a CC or MCC.

CC/MCC grouping rules are adjusted each year, so check the rules for the fiscal year of the patient's discharge date.

DRG Mapping Rules for J14

Diagnostic codes are the first step in the DRG mapping process.

The patient's primary diagnostic code is the most important. Assuming the patient's primary diagnostic code is J14, look in the list below to see which MDC's "Assignment of Diagnosis Codes" is first. That is the MDC that the patient will be grouped into.

From there, check the subsections of the MDC listed. The patient will be mapped into the first subsection for which the treatment performed on the patient meet the listed requirements of that subsection.

DRG grouping rules are adjusted each year, so make sure to check the rules for the fiscal year of the patient's discharge date.
