Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Code First
Code FirstCertain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
Index to Diseases and Injuries References
The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

- - neonatal - P91.819
- - in diseases classified elsewhere - P91.811
- - neonatal - P91.819
Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:
- Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.
Present on Admission (POA)
P91.811 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
POA Indicator | Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |
Replacement Code
P91811 replaces the following previously assigned ICD-10-CM code(s):
- P91.8 - Other specified disturbances of cerebral status of newborn
Convert P91.811 to ICD-9-CM
- ICD-9-CM Code: 779.1 - NB cereb irrit NEC/NOS
Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
