A4479 takes effect and enters the Bowel Management Devices policy

LCD L36267 revision 12 reads "Added: A4479 to Group 1 Codes", with a revision effective date of 04/01/2026. Policy Article A54516 revision 14, effective the same day, added the coding guideline for A4479 and the billing instruction for claims with dates of service on or after April 1, 2026. Before that day the electronic transanal irrigation system had no code of its own in the policy.

The billing instruction is the operative half. A4479 and A4453 are the correct codes to bill; A4479 is not an all-inclusive code at initial issue because it does not include the disposable rectal catheter; separate billing of that catheter under A4453 is payable at initial issue; and refills of the catheter must be billed as A4453.

The announced date recorded here is the date the LCD prints beside its note that, pursuant to the 21st Century Cures Act, these revisions did not require notice and comment because they are non-discretionary updates to CMS HCPCS coding determinations. CMS's alpha-numeric HCPCS file gives the code an added date of April 1, 2026, and the Jurisdiction C supplier manual prints it stamped as effective the same day.

Coverage API weekly snapshot, data captured through 2026-08-02 and refreshed 2026-08-06; the API is not a live read. Seeded now because it governs the hub's three bowel-management codes and its `policy` document has to exist before those pages reference it. All 58 DME MAC LCDs were swept and their HCPCS lists queried: this is the only one in the set containing A4453, A4459 or A4479, and none of the three appears in L33803.

Seeded alongside L36267 for the bowel pages. It publishes no HCPCS table of its own: /v1/data/article/hcpc-code, code-table, icd10-covered and icd10-noncovered all return zero rows for it, which is a structural fact about this policy rather than a fetch failure. The codes live on the LCD.

    THE AUTHORITATIVE REGISTER OF CODE STATUS, and the one document that answers questions the coverage determinations cannot: when a code was added, whether it has been terminated, and what kind of change was last made to it. Downloaded on 2026-08-07 from https://www.cms.gov/files/zip/july-2026-alpha-numeric-hcpcs-file.zip, HTTP 200, 2,499,217 bytes, SHA-256 5591fed257e4d2307c1d2dc9c66abc8e346b1f4c076e9e48559799e2de14b70a; the data file inside is HCPC2026_JUL_ANWEB_06172026.txt and the field positions are documented in HCPC2026_recordlayout.txt in the same archive. Read here for four records. A4353: code added date 19970101, action effective date 20030101, action code N for no maintenance, and NO termination date, which is the register-level confirmation that the code is live. A4297: added 20260101. A4479: added 20260401, action code S for a change in short description, action effective date 20260701, no termination date. A4351: added 19900101 with an action effective date of 20260101, the descriptor revision. The long description field is 80 characters and the short description 28, so a long descriptor read from this file alone can be truncated; the full text belongs to the coverage documents cited beside it.

    CITE THE APPENDIX AND THE PAGE, NOT THE FILE. The relevant content is Appendix A, Level II HCPCS Codes: A4295, A4296 and A4297 on PDF page 249, A4351 to A4353 on page 250, and the transanal irrigation codes on pages 254 to 255. PDF, HTTP 200, 5,694,794 bytes, 448 pages, fetched 2026-08-07. Programmatic extraction needs a crypto backend: the file is AES-encrypted with an empty user password, so pypdf alone raises a dependency error and pypdf with cryptography reads all 448 pages with no password prompt. THE MANUAL CARRIES NO COVERAGE OR QUANTITY RULES, and says so: "The Level II HCPCS listed in Appendix A of this manual are provided as a guide for identifying items that are processed by the DME MACs. The appearance of a code in the appendix does not necessarily indicate coverage." Cited here for the descriptors as the DME MAC prints them, each stamped with its effective date.
