![]() ![]() For each code under category 250 there is a use additional code note for the manifestation that is specific for that particular diabetic manifestation. The most commonly used etiology/manifestation combinations are the codes for Diabetes mellitus, category 250. The code in brackets is always to be sequenced second. In the Index both conditions are listed together with the etiology code first followed by the manifestation codes in brackets. In addition to the notes in the Tabular, these conditions also have a specific Index entry structure. ![]() For such codes, a “use additional code” note will still be present and the rules for sequencing apply. There are manifestation codes that do not have “in diseases classified elsewhere” in the title. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition. “In diseases classified elsewhere” codes are never permitted to be used as first listed or principal diagnosis codes. The code title indicates that it is a manifestation code. In most cases the manifestation codes will have in the code title, “in diseases classified elsewhere.” Codes with this title are a component of the etiology/manifestation convention. These instructional notes indicate the proper sequencing order of the codes, etiology followed by 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. For such conditions, the ICD-9-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Etiology/manifestation convention (“code first,” “use additional code,” and “in diseases classified elsewhere” notes)Ĭertain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. These index entries represent specific disease entities for which no specific code exists so the term is included within an “other” code.Ĭodes (usually a code with a 4th digit 9 or a 5th digit 0 for diagnosis codes) titled “unspecified” are used when the information in the medical record is insufficient to assign a more specific code.Ħ. Index entries with NEC in the line designate “other” codes in the tabular. ![]() Additional terms found only in the index may also be assigned a code.Ĭodes titled “other” or “other specified” (usually a code with a 4th digit 8 or a fifth-digit 9 for diagnosis codes) are for use when the information in the medical record provides detail for which a specific code does not exist. The inclusion terms are not necessarily exhaustive. The terms may be synonyms of the code title, or, in the case of “other specified” codes, the terms are a list of the various conditions assigned to that code. These terms are the conditions for which that code number is to be used. Inclusion terms: List of terms is included under certain four and five digit codes. Both codes may be used together if both types of fractures are present. An example of this is when fractures of different bones are coded to different codes. In other cases, the excluded terms may be used together with an excluded code. ![]() The congenital and acquired codes should not be used together. An example of this is a congenital condition excluded from an acquired form of the same condition. In some cases the codes for the excluded terms should not be used in conjunction with the code from which it is excluded. Includes: This note appears immediately under a three-digit code title to further define, or give an example of, the content of the category.Įxcludes: An excludes note under a code indicates that the terms excluded from the code are to be coded elsewhere. ![]()
