More Clarifications for ICD-10 Change

The National Association for Home Care & Hospice (NAHC) has recently learned that the organizations responsible for the official ICD-10 coding guidance has issued clarification that would require home health agencies to indicate an “A” (initial encounter) in the 7th character for some ICD-10 codes. An “A” in the 7th character should be used for any encounter where the patient is still receiving active treatment for the clinical condition, including home health.

Experts have writing a term paper understood that an “A” would never be appropriate as the 7th character for a home health diagnosis. The reason being is the patient would have been seen initially in another setting. But, the initial encounter definition in the ICD-10 coding guidelines is broader than experts realized.

In the ICD-10-CM Official Guidelines for Coding and Reporting, the following language is used to help coders determine when an “A” should be used in the 7th character:

“While the patient may be seen by a new or different provider over the course of treatment for an injury, assignment of the 7th character is based on whether the patient is undergoing active treatment and not whether the provider is seeing the patient for the first time.”

“For complication codes, active treatment refers to treatment for the condition described by the code, even though it may be related to an earlier precipitating problem. For example, code T84.50XA, Infection and inflammatory reaction due to unspecified internal joint prosthesis, initial encounter, is used when active treatment is provided for the infection, even though the condition relates to the prosthetic device, implant or graft that was placed at a previous encounter.”

The 2015 Home Health Grouper does not allow for case mix and non-routine supply points for any ICD-10 code with an “A” as the 7th character.

NAHC is currently waiting for confirmation from CMS on how this issue will be addressed. Since it is unlikely that the Home Health Grouper can be updated this close to the ICD-10 implementation date, claims may need to be adjusted.
