ICD-10-CM A54.41
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

A54.41 is a billable ICD-10-CM diagnosis code for gonococcal spondylopathy. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 456 through 458, 539 through 541. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 1,070 closely related codes. Coders also document this condition as gonococcal spondylitis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Sexually transmitted infections (excluding HIV and hepatitis) and Spondylopathies/spondyloarthropathy (including infective).

For Medicare Advantage risk adjustment, A54.41 maps to CMS-HCC Category 92 (Bone/Joint/Muscle/Severe Soft Tissue Infections/Necrosis) under the V28 model, adding a risk factor of about 0.479 for a community, non-dual, aged beneficiary in payment year 2027.

Patient EducationClinical

Gonorrhea

Gonorrhea is a sexually transmitted infection (STI). It is most common in young adults. The bacteria that cause gonorrhea can infect the genital tract, mouth, or anus. You can get gonorrhea during vaginal, oral, or anal sex with an infected partner. A pregnant woman can pass it to her baby during childbirth.

Questions About A54.41Overview

What is the ICD-10 code for gonococcal spondylopathy?

The ICD-10-CM code for gonococcal spondylopathy is A54.41 (sometimes written as A5441). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is A54.41 (Gonococcal infection of musculoskeletal system) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report gonococcal spondylopathy on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does A54.41 group to?

When gonococcal spondylopathy is the principal diagnosis on an inpatient stay, it groups to MS-DRG 541, 456, 457, 539, 540, 458, with relative weights from 0.8293 to 7.6211 depending on complications. Higher weights mean higher Medicare reimbursement.

Is A54.41 a CC or MCC?

CMS lists A54.41 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 1,070 closely related codes in its exclusion list.

Can A54.41 be reported with N34.1?

Not as a rule. The Excludes1 note at block A50-A64, which applies to A54.41, lists "nonspecific and nongonococcal urethritis (N34.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What HCC is A54.41?

A54.41 (gonococcal spondylopathy) maps to CMS-HCC Category 92 (Bone/Joint/Muscle/Severe Soft Tissue Infections/Necrosis), commonly written as HCC 92, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 39 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does A54.41 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, A54.41 adds a risk adjustment factor of about 0.479 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.471 to 0.632 depending on the payment segment). HCC 92 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 92 category page.
