This is a shortened version of the first chapter of the ICD-9: Infectious and Parasitic Diseases. It covers ICD codes 001 to 139.
ICD-9-CM diagnosis codes are composed of codes with 3, 4, or 5 digits. Codes with three digits are included in ICD-9-CM as the heading of a category of codes that may be further subdivided by the use of fourth and/or fifth digits, which provide greater detail.
This is a shortened version of the first chapter of the ICD-9: Infectious and Parasitic Diseases. It covers ICD codes 001 to 139. The full chapter can be found on pages 49 to 99 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The conventions for the ICD-9-CM are the general rules for use of the classification independent of the guidelines. These conventions are incorporated within the index and tabular of the ICD-9-CM as instructional notes. The conventions are as follows: 1.

ICD-10-CM Code for Other disorders of lung J98. 4.
According to Coding Clinic, chronic restrictive lung disease is assigned to code 518.89, Other diseases of lung, not elsewhere classified. It also says that chronic restrictive lung disease “is an ill-defined term, however, and should be used only when the condition cannot be described more specifically.”

Restrictive lung disease, a decrease in the total volume of air that the lungs are able to hold, is often due to a decrease in the elasticity of the lungs themselves or caused by a problem related to the expansion of the chest wall during inhalation.
ICD-10-CM J41. 8 is grouped within Diagnostic Related Group(s) (MS-DRG v39.0): 190 Chronic obstructive pulmonary disease with mcc.

Chapter 16 of ICD-9-CM, Symptoms, Signs, and Ill-defined conditions (codes 780.0 - 799.9) contain many, but not all codes for symptoms.
The conventions for the ICD-9-CM are the general rules for use of the classification independent of the guidelines. These conventions are incorporated within the index and tabular of the ICD -9-CM as instructional notes. The conventions are as follows:
Codes under category 250, Diabetes mellitus, identify complications/manifestations associated with diabetes mellitus. A fifth-digit is required for all category 250 codes to identify the type of diabetes mellitus and whether the diabetes is controlled or uncontrolled.
If a patient is documented as having both MRSA colonization and infection during a hospital admission, code V02.54, Carrier or suspected carrier, Methicillin resistant Staphylococcus aureus, and a code for the MRSA infection may both be assigned.
Codes from categories 760-763, Maternal causes of perinatal morbidity and mortality, are assigned only when the maternal condition has actually affected the fetus or newborn. The fact that the mother has an associated medical condition or experiences some complication of pregnancy, labor or delivery does not justify the routine assignment of codes from these categories to the newborn record.
When coding the birth of an infant, assign a code from categories V30-V39, according to the type of birth. A code from this series is assigned as a principal diagnosis, and assigned only once to a newborn at the time of birth.
Subcategory 733.1 may be used while the patient is receiving active treatment for the fracture. Examples of active treatment are: surgical treatment, emergency department encounter, evaluation and treatment by
Dr. Jeffrey Linzer, AAP, recommended retaining the code for underdosing of morphine and fentanyl (currently indexed at code T40.2x6, Underdosing of other opioids). Nelly Leon-Chisen, AHA, recommended retaining the codes in subcategory Z91.12, Patient’s intentional underdosing of medication regimen and code -Z91.14, Patient’s other noncompliance with medication regimen. She and others felt it was important to have the ability to track this especially as it may relate to caregiver noncompliance and underdosing.
Nelly Leon-Chisen, American Hospital Association, (AHA) suggested that the title of proposed code 793.12 indicate that it is referring to “more than one nodule” and not “more than one finding” on radiological and other examination of lung field.
Comments included general support for the proposal. In addition, since the minimum score for the Glasgow Coma Scale is 3, it was suggested that the title for proposed new code R40.243 be “Glasgow coma scale score 4-8” (instead of 3-8) and the title for proposed new code R40.244 should be Glasgow Coma Scale score 3. Alternatively, the proposed code R40.244, Glasgow Coma Scale score less than 3, could be eliminated. Concern was also raised that the proposed code R40.245, Other coma, without documented Glasgow Coma Scale score, or with partial score reported, would overlap with code R40.20, Unspecified coma.
Comments included general support for the proposal. The AHA representative, Nelly Leon-Chisen, stated that the proposal would change the meaning of 999.31, and suggested creating new separate codes for the bloodstream infection, and the local infection, and keeping the existing code as an unspecified infection due to central venous catheter. Dr. Linzer suggested adding the term cellulitis for local infections; he also questioned whether someone presenting with fever but not septic, in whom the catheter was removed and cultured positive, would be coded to the local infection code. A question was raised about coding septicemia with the proposed code, and it was noted that the existing note at 999.3 to use additional code for the infection would indicate this should be done. It was suggested to add the term pocket for local infection.
The ICD-9-CM Coordination and Maintenance Committee will implement a partial freeze of the ICD-9-CM and ICD-10 (ICD-10-CM and ICD-10-PCS) codes prior to the implementation of ICD-10 on October 1, 2013. There was considerable support for this partial freeze. The partial freeze will be implemented as follows:
Aggressive periodontitis currently is categorized as either localized, generalized, or unspecified depending upon the extent of the disease process. The 1999 International Workshop for a Classification of Periodontal Diseases and Conditions1 further characterized the diseases on the basis of their severity. As a general rule, extent is the number of teeth involved; if <30% are involved, it is considered to be localized, while if >30% are involved it is considered to be generalized. Further granularity is provided when disease severity is described on the basis of clinical attachment loss (CAL), either for the entire dentition or for individual teeth. Generally, Slight = 1-2 mm CAL, Moderate = 2-4 mm CAL, and Severe = >5mm CAL.
