MDS & CODING NEWS:

Is your SNF on top of these errors in the 2009 ICD-9 Manual?

Published on Sun Feb 15, 2009 Print Friendly and PDF PDF

The American Medical Association recently identified several corrections to its 2009 ICD-9 manual that you'll need to note to ensure your diagnosis coding is on the mark.

For example, some coders have discovered a "5th digit" requirement next to code 339.3 (Drug induced headache, not elsewhere classified) in the manual. This notation was, however, an error in the manual. The AMA instructs that 339.3 "Is a valid four-digit code." The same is true for 719.7 (Difficulty in walking); this remains a four-digit code.

The same holds true for chemical exposure. You can also scrap the "5th digit" requirement for new code V87.2 (Contact with and [suspected] exposure to other potentially hazardous chemicals). Only four digits are required for this code.

Wrong 5th digit published: Another puzzler was the inclusion of the fifth digit box preceding category 535, Gastritis and Duodenitis.

The box in the ICD-9 manual notes that fifth digit indicator 0 describes "without mention of obstruction," while a fifth digit of 1 notes, "with obstruction." However, you should change these descriptors to the following:

0 - Without mention of hemorrhage

1 - With mention of hemorrhage

"Since most of the codes in the 535 series require a fifth digit, it's important for us all to make this correction in our ICD-9 manuals now to avoid problems down the road," says Heather Corcoran with CGH Billing.

5th digit required: In other cases, the ICD-9 manual failed to inform readers that a fifth digit was required on certain codes. For instance, you'll need to add a fifth digit to code 581.8 (Nephrotic syndrome, with other specified pathological lesion in kidney).

The index also includes errors: The ICD-9 errata sheet also asks you to change several code references in the manual's index. For example, if you look up "headache" (784.0),you'll find "tension" as one of the listed options. In the manual, it refers to a tension headache as code 307.81. You should change this reference to 307.10 instead.

Background: The updates seem to have been made to an index from several years ago -- so many of the newer codes from the last few years aren't in the alphabetic index but do appear in the tabular list. Unfortunately,many ICD-9 manual publishers didn't catch the error until after they had downloaded the errors into their 2009 versions of the manual.
