261 is a legacy ICD-9-CM diagnosis code for nutritional marasmus. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, it maps to 2 ICD-10-CM candidates: E41 and E43.

Information for Patients

Malnutrition

Food provides the energy and nutrients you need to be healthy. If you don't get enough nutrients -- including proteins, carbohydrates, fats, vitamins, and minerals - you may suffer from malnutrition.

Questions About 261

Is 261 (nutritional marasmus) still a valid code?

No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as E41 and E43.

What is the ICD-10 replacement for 261?

The General Equivalence Mappings list 2 ICD-10-CM candidates for this code: E41 (Nutritional marasmus) and E43 (Unspecified severe protein-calorie malnutrition). Each match is approximate, so the right choice depends on what the documentation supports.

What did 261 mean?

In the final ICD-9-CM release, this code described nutritional marasmus. It sat in block 261 Nutritional marasmus under Endocrine, nutritional and metabolic diseases, and immunity disorders (240–279).

Why does 261 map to more than one ICD-10 code?

ICD-10-CM is more specific than ICD-9-CM. The detail packed into this single legacy code was split across E41 and E43, so the General Equivalence Mappings list every candidate rather than forcing one. The correct target is the one the documentation supports.
